Current Version : Alpha 16

RimWorld Alpha 16 – Wanderlust is released! This update adds a spherical world and the ability to travel across it with multiple caravans, having simultaneous encounters on the way and settling new colonies.

If you’re on Steam, your game will update automatically. Because of huge structural changes to the game, this update will break save games. If you want to continue an old save just change to the “alpha15” beta branch on Steam. To do so, go to Steam library, right-click RimWorld, click Properties, click the Betas tab, and use the drop-down to select the branch you want.

If you’re not on Steam, just download from your permanent personal download link – it’s always updated to the latest version.

Release Trailer

Changes

Spherical planet

  • World map is now modeled as a sphere covered with hexagons (and a few pentagons).
  • New map generation to make nicer mountain ranges, hill clusters, and continents.
  • Nice backdrop with stars and sun.
  • Time of day is modeled on the planet view; local time of day corresponds to how the sunlight hits the planet.
  • Time zones are now modeled, out of necessity.
  • New planet generation parameter: temperature. You can make worlds that are overall hotter or overall colder.
  • New planet generation parameter: rainfall. You can make worlds where there is overall more or less precipitation.
  • New biome: sea ice.
  • Factions can now have many bases; non-player factions generate with lots of bases.

Multiple simultaneous maps

  • There can now be multiple local maps active at once. For example, you can have your colony running as well, as a group of soldiers attacking an enemy base, at the same time.
  • The character bar at the top of the screen shows all of your colonists and allows you to change which map you’re looking at. It groups characters togehter by the map they’re on.
  • You can settle multiple colonies at once. However, for balance and performance reasons, the default limit is one colony at a time. This can be increased in the options menu if you want to experiment, but we don’t recommend it.

Caravans

  • Player can now gather up groups of colonists, prisoners, and animals, and form caravans to travel across the world surface.
  • Caravans are formed using a special “create caravan” dialog, which allows you to easily decide what people, animals, and items should be included in the caravan up to its carry weight limit. The colonists do the busywork.
  • Caravans appear as units in the world map, where they can be ordered around similarly to drafted soldiers in the local map.
  • Caravans can be ambushed by enemy factions or manhunting animals. This produces a temporary local map.
  • Caravans can incidentally meet friendly traders and trade.
  • Caravans can visit other faction bases and trade with them. Faction bases have more stock and better prices than traders who come and visit your colony.
  • Caravans can attack faction bases. The game generates a simple faction base map with defenders and loot, and you raid it. If you defeat the defenders, you can move in and take over the base (for now, generated bases are quite simple.)
  • Caravans can settle and form new colonies.
  • You can abandon your bases to shift to new ones.
  • Caravans move at different speeds depending on the biome, the time of year (cold biomes close off with the winter snows), local hilliness, the movement speeds of people in the caravan, and whether there are wounded to carry.
  • It is possible to abandon people and items from caravans. Abandoning people will, depending on the context, produce sad thoughts from their friends and relatives, especially if you abandon them in circumstances that seem impossible to survive.

Travel victory

  • New game ending: A friendly person offers a ship, but it is distant, across the world map. If you travel there, you can escape the planet and complete the game. But, traveling there will take a long time and you’ll need to stop at various points to build up supplies or solve problems.

Transport pods

  • You can build transport pod launchers and transport pods. These let you launch their contents long distances across the world map, over oceans or mountains.
  • Pods can be targeted on empty world tiles, to send a caravan of people and gear there.
  • Pods can be targeted on enemy bases, where you can perform “drop-in” raids and drop right on top of the base, or drop outside it – just like raiders do to you!
  • Pods can be targeted on existing combat maps or other bases you control. This allows you to do things like resupply an ongoing siege with artillery shells (just like raiders do when besieging you), reinforce a weak caravan that just got ambushed, or send supplies and people between two bases you control.
  • Pods are loaded by selecting several and creating a “launch group”. An interface like that for creating caravans appears, allowing you to define what and who should be included. The colonists do the detail work.
  • Transport pods require chemfuel, which can be bought, founded, drilled from the ground, or refined from wood or food using the new refinery building.

Usability improvements

  • New research screen! Research projects are laid out visually according to their dependencies in a left-to-right arrangement similar to the Civilization games. Modders need to manually place their projects, but if two overlap the game will automatically move them apart.
  • Redesigned how medical system generates text feedback. Tooltips now contain much more information with less ambiguity. Wound tendings are now of any percentage quality (not just good/poor).
  • Game now warns you when you order slaughter of a bonded animal (because of the mood impact).
  • Added visual feedback thought bubbles for when pawns gain certain good and bad thoughts, so it’s easier to see when something just bothered or pleased them.
  • Rich soil is darker in color and so easier to see.
  • Added a “hold fire” toggle on drafted pawns that makes them not automatically shoot at enemies.
  • In order to avoid annoying players by having animals always follow their masters, even into combat, players can configure when animals will follow their masters. There are two toggles: Follow while drafted, follow while hunting/taming

Drugs and health

  • Drug rebalance. Increase drug addictiveness in general. Drugs can now damage the body in various ways: Alcohol can cause brain damage or liver cirrhosis or liver cancer, smokeleaf can cause asthma or lung cancer, psychite can damage kidneys, wake-up and go-juice can damage the brain, and generalized overdoses can cause brain damage.
  • Drugs are more lucrative on the market.
  • Added a third toggle in drug policy saying whether you can use the drug to feed an addiction, separately from joy usage.
  • There is now a random chance of a overdose when taking drugs, even if just taking one dose.
  • Added a way to administer specific drugs to people, including prisoners, animals, and downed people. So you can give Luciferium to someone who needs it.
  • Malari-block reworked into Penoxycyline, which prevents a wide variety of infections (not just malaria).
  • Drug chemical effects are modulated by body size. So elephants need a lot of beer to get hammered; squirrels not so much.
  • Luciferium occasionally heals old wounds/scars. Luciferium is harder to get (less of it in old shrines, higher prices).
  • Stats now stack differently (more additive, less multiplying) to reduce some exploits.

Misc

  • Reworked surgery failure into three modes – minor, catastrophic, and ridiculous. Ridiculous hits all body parts, minor and catastrophic hit parts near the surgery site.
  • Reworked trade prices across the board. Simplified trade price calculations and added rich tooltips to feed them back.
  • The mood effects from room impressiveness have been redesigned and rebalanced. Characters now have consistently reasonable thoughts about the quality of their personal room, so there is a reason to make better rooms (though high-quality rooms aren’t absolutely necessary). Mood effects from eating in or convalescing in nice/poor rooms are also more reasonable and better-fed back.
  • Rebalanced plant growth timings.
  • UI can now be scaled to arbitrary scaling factors, for players who play in really high resolution.
  • Rescued people (especially space refugees etc) should sometimes join the colony. If the environment isn’t survivable (e.g. bad temperature, toxic fallout) they should always join the colony.
  • Animals carrying inventory now have visible packs on.
  • Added new separate bills to stonecut each type of stone.
  • Prisoners are now temporarily marked “guilty” when they do certain actions, like killing a colonist or attempting escape. Guilty prisoners can be executed without mood penalties.
  • Faction names are now much more interesting and varied, and are separate from specific community names.
  • New Peaceful difficulty mode, for players who just want to build stuff. Disables major involuntary threats like raids.
  • Rename Megatherium -> Megasloth
  • New alert: Unhappy nudity
  • Backstories can be translated now
  • New translation tool gives a readout of exactly what translation data remains to be written and what data is unused.
  • Added proper chick peeping sounds.
  • You can now only request one trader per 4 days from a faction.
  • Colonists now get mood boosts for defeating big enemies or enemy faction leaders.
  • Cleaning and harvesting jobs are now given in batches (more efficient and sensible AI).
  • Default medical care for non-colonists is now herbal meds. Switches to best meds on recruit.
  • Rebalanced most range weapons so more time is in cooldown and less is in aiming – especially for light weapons.
  • Pawns generated below age 20 now have no adulthood backstory.
  • Hundreds of other balance improvements, exploit solutions, AI improvements, and bugfixes.

Recent Version : Alpha 15C

Alpha15c is currently on Steam’s ‘unstable’ branch for public testing. This update fixes some important bugs and yield significant CPU usage optimizations. It also adjusts a few balance points for a better experience. I invite everyone willing to choose the unstable branch and test it out! I invite feedback in this forum thread and in the comments here.

Save compatibility: Savegames from the unmodded game will be compatible from earlier Alpha 15 versions.

Mods compatibility: Data and XML mods will be 100% compatible from earlier Alpha 15 version. The API for code mods is also unchanged, and so should remain compatible. However, since the core game has been recompiled, some mods may need to be recompiled as well before they work again. Mod authors may want to look at Alpha15c to check and prepare compatibility. (This shouldn’t require any actual code or data changes, but may require recompiling your code).

Once Alpha15c is confirmed stable, I will release it to all users. Hopefully within a day or two.

Changes

  • Fix: Luciferium is not addictive; it gives the positive effect forever with no downside.
  • Fix: Malari-block high never goes away.
  • Optimized a bunch of pawn ticking code to be much, much faster.
  • Rebalanced drugs to be a bit more profitable and a bit more more dangerous.
  • Food selection algorithm prefers meals by 16 cells instead of 7.
  • Fix: Game doesn’t assign short hashes if you subclass any Def class. This makes many mods impossible.
  • Fix: Standing lamps and sun lamps are available without research.
  • Fix 2618: On Linux, system language can break the game.
  • Fix: Raiders can steal during tutorial.
  • Fix 2620: Learning Helper: Items remain after save-scum.
  • Fix 2611: Scenario ‘Can’t Hunt’ etc doesn’t work.
  • Translations update.
  • Some other misc minor fixes, rebalancings and text changes.

Recent Version : Alpha 15B

A tiny update to Alpha15b has been released that fixes a small bug with Cassandra Classic and Phoebe Chillax.

DRM-free players can update by simply re-downloading from their existing download link. It always carries the latest version. (Don’t worry about running out of downloads, you can always email support for a reset. We just have that limit to stop automated abuse.)

These storytellers were miscounting the days since game start, and so were sometimes incorrectly sending a several raids in the 5-10 day range, making this crucial part of the early game far too hard.

This update is tiny (two lines of code) so it shouldn’t affect compatibility with saves or mods.

However, because it will shift the storyteller’s timer, it may cause some players to get a string of raids in a row, or a long peaceful period. This will only happen once.

Recent Version : Alpha 15

I’m happy to announce that we’ve just released RimWorld Alpha 15! This version adds a rich tutorial, an intelligent learning helper to help you pick up the game, a new drug system, deep drilling to provide resources in the end game, and a giant pile of other smaller improvements and fixes. A full change log and detailed info is below.

For Steam players, if you want to continue with Alpha 14 for any reason, you can get on the ‘alpha14’ beta branch in Steam. In the Steam Library, right click RimWorld, click Properties, go to the Betas tab, select alpha14 in the drop-down list, and restart Steam.

Non-Steam players who wish to update can simply download from the same download link as before; it has been updated to the new version. They should install the new version in a clean empty folder.

Compatibility

Save Compatibility

As usual, Alpha 15 will not load Alpha 14 save games by default. However, a user did put together a guide that allows you to manually update save files with some text editing. Check it out here if you really want to try to continue that Alpha 14 colony.

Mod Compatibility

Some purely XML mods will be compatible between versions. However, most significant mods will need to be adjusted and recompiled. Beware: If a mod author updates their existing mod to the new version, it’ll stop updating on the old version. You may wish to turn off Steam auto-updates if you really want to avoid this.

Release Trailer

Changes

Tutorial

  • Added new rich tutorial with step-by-step instructions.
  • Tutorial teaches the basics of setting up a game, building a small self-sustaining colony, and defeating the first
  • raider.
  • Tutorial locks out irrelevant controls and highlights relevant controls.
  • At the end of the tutorial, the player can continue the game with a normal storyteller.

Learning helper

  • Added new learning helper system to replace yellow pop-up messages and yellow learning alerts.
  • Learning helper sits in the top right of the screen. If something happens relating to a concept the player hasn’t learned, that lesson will be activated and shown on the learning helper. It can then be opened and read. Lessons are automatically marked as learned when the player does the necessary interaction, and can be marked as learned manually. Lessons are shown as needed by circumstance, or on a slow timer. The overall idea is that you’ll never be shown a lesson you already know, but always be shown the lessons you need to know now.
  • Learning helper can be expanded and searched for any lesson, so you can look up how to do a specific thing at any time.

Drugs system

  • Added new drugs system. It’s not just beer any more!
  • Drugs typically create up to four effects. Not all drugs have all effects.
  • Primary – The valuable short-term effect, whether it improves mood or work focus or combat effectiveness or makes one immune to a disease.
  • Overdose – Excessive drug usage in a short time can build up blood toxicity, leading to unconsciousness and possible death.
  • Tolerance – Long-term usage of a drug can build up a tolerance which makes subsequent usage less and less effective in producing the high.
  • Addiction – Drug use can form an addiction. This generates a new need for the drug which the pawn will try to feed regularly. If the need isn’t fed, the pawn will develop withdrawal symptoms (low mood, reduced consciousness). Eventually withdrawal will pass and the addiction will go away.
  • Drugs can be assigned for regular taking through the drug policy system. Similar to Outfits, drug policies are an assigned schedule for taking drugs. You can set any number of drugs, each with a frequency. For example, you can assign a colonist to drink 2 beers every day, and take one Malari-Block every 5 days.
  • The drugs are:
    • Beer – Improved mood but worsened capacities. Addictive.
    • Malari-block – Prevents malaria infection for 5 days.
    • Yayo – Stimulant pleasure drug, addictive.
    • Flake – Cheap, short high, very addictive.
    • Wake-up – Improves work performance, addictive.
    • Smokeleaf – Improved mood but worsened capacities. More hunger, slower movement. Can form dependence.
    • Go-Juice – Synthetic futuristic combat drug. Boost speed and fighting capacity tremendously. Addictive.
    • Luciferium – Glitterworld mechanites that give huge bonuses to most capacities. However, without repeated doses the user goes insane and dies. It is impossible to clear the addiction, and the drug is 100% addictive on one dose.
  • Drugs are produced in various ways, typically at the new Drug Lab building, from various precursor chemicals and growable crops. They require research to create.

Deep drilling

  • The map now spawns with clusters of underground resources. These can be accessed by building a deep scanner to find them, and then building deep drills on top of them, and then working the drills. This slowly produces the resource.
  • Deep drilling tech is at the end of the tech tree. This should mitigate late-game resource exhaustion problems.

Misc

  • Mood is now drawn subtly behind the pawn on the colonist readout at the top of the screen.
  • You can now produce medicine from herbal medicine, neutroamine (a precursor chemical you buy), and cloth. Requires research.
  • Added passive cooler building. Made of wood and low tech, it cools a room for a short time. Good for passing heat waves as a tribe.
  • Added a ‘copy building’ tool which lets you quickly select the designator for a building through an existing copy of that building.
  • Beer production now takes several stages: Colonists make wort (unfermented beer) at the brewer table, then leave it in fermenting barrels for a while, after which they can harvest it as beer.
  • Infestation can now only spawn under a thick roof.
  • Gear tab now shows aggregate stats about armor and comfy temperatures.
  • Raider steal a bit more often now.
  • Factored MapGeneratorDef apart into separate GenStepDefs which can be modded or inserted individually. This will allow modders to change the MapGenerator without blowing away each others’ changes.
  • Added alert: Need warm clothes.
  • Mods can now be dragged to reorder them in the mods page.
  • Re-tuned food finding algorithm.
  • Hunters will no longer hunt without a ranged weapon.
  • Debuffed corn a bit.
  • Reworked trade interface to clearly state what kind of trader they are, and to list items they’re not willing to trade.
  • Reworked trader stock generators so traders carry and accept more sensible items for their type.
  • You can now request traders by calling allied factions. It costs silver.
  • Chance to spring known traps is reduced from 2.5% to 0.4%.
  • Friendly fire chances reduced by 60% for fly-by shots (shots that miss and land in the cell with a pawn have the same chance to hit as before).
  • Added a message when food spoils in storage.
  • Fix: Pawns don’t get ‘catharsis’ mood gainer thought after a mental break.
  • Rename PDW to Machine pistol.
  • Torches and campfires are no longer destroyed near-instantly by rain/snow. They instead consume fuel faster.
  • Torches consume fuel a bit faster overall.
  • Fueled generator consumes fuel faster and holds less fuel.
  • Plant sow and harvest are now slower.
  • Debuffed fists.
  • Reduced volume of idle animal calls at high time speeds.
  • Smithing is now a prerequisite for Machining research.
  • Added a toggleable view that shows roofs in glowing green.
  • Hundreds of other balance changes, text fixes, redesigns, and bug fixes.

Recent Version : Alpha 14E

Some rare, game-breaking bugs were reported. Some are crashes; others critically break AI behavior. So I fixed them.

Savegames should continue to work from before. Some savegames that were broken before will now load.

Mods should also mostly be compatible, but there may be issues in some cases given the complexities of how the code links up.

The build number is now 1249.

Non-Steam players won’t get an update email since this isn’t a content update. They can download the new version from their existing download link.

Changes

  • Fix: Hard crash when bed-sharing pawns have zero chance to do lovin’, passing a PositiveInfinity mean-time-between to the random event checker, causing it to enter an infinite loop.
  • Fix: AI stuck when warden chooses to feed a prisoner by taking food from an empty food dispenser.
  • Fix: AI stuck and performance chugging from colony animals starving while being restricted to not touching walls, and locked inside.
  • Mitigate: Sometimes, NPCs in parties, marriages all freeze and just stand there.
  • Mitigate: Game can save a corpse with null innerPawn, which makes the save unloadable.

Recent Version : Alpha 14D

Alpha14d (build 1241) is a quick-fix build that makes a few small but important changes.

DRM-free owners will NOT get an update email, but can download the new build from their existing download link.

Compatibility

Save games from Alpha 14 should still work.

Changes

  • Reduced event density on Randy Random from 1.5x that of Cassandra to about the same as Cassandra. The combination and distribution of events is still very different from Cassandra.
  • Fixed a crash that occurs when the player has no allies.
  • The “cannot connect to Steam API” error message is now more informative and suggests rebooting.
  • Toxic fallout, flashstorm and volcanic winter are now disabled in Free Play difficulty.
  • Toxic fallout and volcanic winter are now rarer.

Recent Version : Alpha 14C

It looks like the fixes in Alpha14b were effective. I’m now releasing Alpha14c on Steam and DRM-free channels. This one is just a tiny change from 14b: Phoebe’s random incidents density is reduced somewhat (it was the same as Cassandra’s before, which doesn’t make sense since Phoebe is supposed to give more breathing space between events.)

I’ll still be watching for balance and content problems, but it seems likely the next patch will be a new alpha.

On a side note, some people have asked whether any more features will be added. The answer is a definite yes. We are currently working on several major new features with the potential to transform gameplay yet again. I can’t wait to show them to you! But, they have to be ready first. I’m also working on a ton of polish tasks.

Recent Version : Alpha 14B

With the flurry of support and fraud combat tasks abating, I took a little while to watch Zeebos’ stream. A discussion was had and it quickly became apparent that a lot of the events in the game weren’t really firing – ever. No heat waves, no crazy animals, no crashed ship parts.

Doing some local testing, I realized how bad it was. Most of the events in the game would never fire.

Holy crap!

I’ve fixed the issue and uploaded a patch to Steam. Your save games will be compatible. The new build is 0.14.1238 – look for that number at the top left of the main menu to confirm you’re running it.

Look at it this way – it’s like releasing a juicy content patch!

Note: I haven’t updated the DRM-free download yet, I’ll do that when I’m a bit more certain the patch is still balanced.

Changes

  • Fix: Events never fire (except in some exceptional circumstances):
    • Infestation
    • Manhunter pack
    • Psychic ship part crash
    • Poison ship part crash
    • Animal insanity (single)
    • Eclipse
    • Solar flare
    • Psychic drone
    • Toxic fallout
    • Volcanic winter
    • Heatwave
    • Cold snap
    • Flashstorm
    • Short circuit
    • Crop blight
    • Alphabeavers
    • Psychic soothe
    • Refugee chased
    • Thrumbo passes
  • Fix: Storyteller incorrectly adjusts trader frequency in relation to ally count.
  • Fix: Threat cycle event maker sometimes queues events without enough points to actually fire them.

Recent Version : Alpha 14

The day is finally here. RimWorld is now available on Steam! You can buy it at the RimWorld Steam Store page. It’s got full support for Steam Workshop and Cloud saves.

Also, Alpha 14 – Scenario System is out! For full information Alpha 14, including the change list, look at the Alpha 14 preview thread.

More good news – everyone who owns the game can move it to Steam. Hooray! You get a Steam key! And you get a Steam key! To get your Steam key, go to the automated link and key sender.

(EDIT: The following no longer applies. Due to fraudster attacks, we’ve been forced to cut off Steam keys for new purchases from our site. You can still buy directly on Steam, of course, at the same prices.) A business note – If you want, buying it from our site is better for us. This way, we get significantly more of the money, since Steam isn’t taking their cut. You can still immediately grab your Steam key and put the game on your Steam account. Obviously we’ll still be very happy if you buy it either way!

Just for fun, for those who are interested, I’m posting the full change list for Alpha 14. Previously, you saw the change summary. This file, however, shows every ‘commit’ (package of code changes) we contributed to our code repository to transform the game from Alpha 13 to Alpha 14.

Each line is one commit. Some are just a few minutes of work, others can be a whole day. Some are by me, others are by ison.

Release Trailer

Note From Devs

On a final, more serious note – please don’t buy Steam keys from third-party sellers. The only ways RimWorld has ever been sold are on our website or on Steam itself, which means that any key being resold is a stolen or improperly sold one. The common scam is this: Hackers steal thousands of credit cards, use them to buy copies of the game from our website, redeem the Steam keys, and then sell these keys at half price. The credit card holder eventually notices the fraudulent purchase and gets it reversed. The end result is that the scammers keep the sale money, and we lose a sale, and we lose the chargeback fees incurred by payment providers (which can be $15 per copy!). It can add up to hundreds of thousands of dollars. So buying these keys is much worse than piracy, because it takes money directly from us, and gives money to thieves. We will be working to make it more difficult for scammers to pull this off, and disabling stolen keys where we find them, so any key bought at a third party likely won’t work. Buy original and all should be good.

Changes

Combat

  • Pawns can no longer overlap during melee combat (unless they’re really small). No more animal deathstacks! This also creates new tactics around blocking, surrounding, or back-line shooters. We had to write a bunch of AI and blocking code to make this function.
  • Projectiles fired by hunting colonists no longer intercept random targets.
  • AI now runs away from grenades thrown by their own faction.

Pawn AI

  • Predators no longer hunt boomrats and boomalopes.
  • Pawns will be smarter about avoiding traps in various situations.

Social

  • Humans now do incest.
  • Beauty trait now has four stages: Staggeringly ugly, ugly, pretty, beautiful.
  • Some backstories now force pawns to have a given trait (e.g. Model->Beautiful)

Buildings

  • Roofs must now be manually built and torn down by colonists; they do not appear and disappear instantly any more.

Animals

  • Tortoises aren’t so deadly any more.
  • Animals no longer do incest.
  • Nuzzling is now a visualized, recorded social interaction.

Interface

  • Ground fertility is now reported on mouseover.
  • Trading interface now lets you type in the number you want to trade instead of dragging to the number.
  • Reworked the right-click menu to be prettier, more readable, more solid, and better handle large lists of options.

Incidents

  • Raiders can now enter “steal” mode if they see enough value. They’ll grab your stuff and carry it off.
  • Kidnapping raiders now work together much better to kidnap. Instead of everyone fleeing at once, some will kidnap while others cover them.

Miscellaneous

  • Full Steam Workshop support for mods.
  • Updated to Unity 5.
  • World generation is now part of the new game process, instead of being separate.
  • Flow for opening worlds and savegames from old version is now improved; the “warning, old version” dialog comes before you open them instead of after.
  • Seeds for world gen are now generated from actual words instead of random letter strings.
  • Deworked mods config menu to have a much nicer selection and ordering interface.
  • Humans can now eat unbutchered corpses (though they really don’t like it).
  • Trade caravans can bring pack dromedaries.
  • Gut worms and muscle parasites vanish sooner.
  • Reworked ancient tomb loot generation. Plasteel is sometimes found on pod people. So are components.
  • Research difficulty is now related to your faction’s tech level. Researching techs above your level is harder. So if you’re a tribe, researching spaceflight will be difficult.
  • Various refactorings to make modding easier and code easier to maintain and more flexible. Much more functionality is now implemented as composable ThingComps.
  • Many, many, many other balance changes, gameplay and interface refinements, and bugfixes.

NewContents

Scenario System

  • New scenario system allows you to choose, randomize, and customize special situations to play in. Determine starting situation, your type of community (tribe, colony), permanent map conditions, starting items, animals, health conditions, and traits, and change special rules.
  • Several built-in scenarios, including one matching the classic RimWorld experience, are included.
  • You can randomize new scenarios.
  • You can customize scenarios with a special interface that allows creation of any scenario you like.
  • Scenarios can be uploaded to or grabbed from Steam Workshop with a single click.
    • ScenPart: Permanent version of all map conditions (eclipse, solar flare, etc).
    • ScenPart: Planetkiller scenario part: World is destroyed on X date.
    • ScenPart: Climate cycle which makes the world get warmer and cooler over a period of years. Winter is coming.
    • ScenPart: Disable building a given type of building.
    • ScenPart: Pawns start with health condition.
    • ScenPart: Start with items.
    • ScenPart: Map is scattered with items.

Incidents

  • Added ‘ransom demand’ incident. Can fire after one of your people is kidnapped.

  • Infestations only appear deeper underground now.
  • Hives now pop out glow pods – bug light sources that glow for 20 days (as long as they’re installed) and can be reinstalled or sold.
  • AI dressing algorithm is now better at making outfits to withstand cold temperatures. If there is no way to make a survivable outfit, pawns won’t arrive at all. No more raids arriving and keeling over in -60C weather.

Social

  • Added “killed my X” social thoughts so people dislike their loved ones’ killers
  • Added new class of “minor” mental breaks, which can happen at mood under 40%.
  • Added minor mental break: food binge.
  • Added traits: creepy breathing, annoying voice. These are socially repellent.
  • Added trait: pyromaniac. Will go on firestarting sprees when stressed, and never puts out fire.

Items

  • Added pemmican for low-tech food preservation.

Buildings

  • Added moisture pump, which slowly converts wet terrain to dry terrain. Requires power.
  • Added torch lamp

Research

  • Added research (needed for tribes only): complex clothing, electricity
  • Added research (needed for non-tribes only): pemmican
  • Added research: air conditioning, autodoors, gun turrets

Animals

  • Added panther for jungle biome. Because I discovered panthers aren’t real and I need to cope with this somehow.
  • Added/replaced animals created by the excellent Kay Fedewa:
    • Caribou
    • Cassowary
    • Deer
    • Emu
    • Arctic fox
    • Fennec fox
    • Red fox
    • Gazelle
    • Husky
    • Ibex
    • Lynx
    • Megatherium (prehistoric giant ground sloth)
    • Ostrich
    • Raccoon
    • Rat
    • Turkey
    • Arctic wolf
    • Timber wolf

Interface

  • Added a row of colonist icons along the top of the screen, with various status info. They can be clicked to select, double-clicked to jump to, or box-selected to multi-select. These icons can be turned off.
  • There is now an orange glow to help you identify very hot areas.
  • Animals tab now has gender and life stage informational columns
  • Animals tab now has a “slaughter” checkbox column to allow easy slaughtering of many animals
  • Animals tab now has checkbox columns for each trainable, to allow easy training of many animals

Miscellaneous

  • You can now play as a tribe in some scenarios.
  • Some traders buy and sell furniture now.

Bugfixes

  • Traders, visitors, raiders, kidnappers, animals, etc will now escape if surrounded by walls with no way out.
  • Manhunters and insects will attack doors if colonists try to hop in and out of them while getting shots off.
  • Hives must now be tended by insects, so if insects are all instantly killed by a turret wall, the hives will die out.
  • You can no longer avoid the ‘executed prisoner’ mood impact by just shooting or starving the prisoner; pawns will get a “prisoner died innocent” thought. A similar solution applies to the deaths of colonists.
  • Solved various powerleveling exploits. Once colonists have learned a certain (high) amount in a day, they’ll learn at a much-reduced rate until the next day.
  • Flowers are no longer good animal feed (reduced nutrition).
  • Fixed exploit where players would give prisoner to raiders for kidnapping, to make raiders go away without a fight. Solution: Raiders only kidnap colonists.
