Cover can be anything that has the possibility to stop a fired bullet from hitting the intended target. Cover in RimWorld can be found in several forms. Some examples are: [[Rubble]], [[Sandbags]], [[Wall|Walls]], the [[Saguaro_cactus|Saguaro cactus]], and even [[animals]].<br/>
 
<br/>
 
<br/>
Cover can be divided in 2 ways, ''high/low cover'' or ''natural/artificial cover''.<br/>
+
 
High cover usually provides better cover than low cover.<br/>
+
'''High cover''' consists of any wall, constructed or otherwise, which a character can lean around to shoot enemies (if they're standing next to the wall). Any wall counts as high cover, and will stop bullets or other projectiles not just from hitting whoever is taking cover behind them, but prevent them from continuing on to hit anything else. It also blocks explosives.<br/>
Artificial cover has a tendency to either start burning, exploding or both, natural cover will, at worst, burn.<br/>
+
'''Low cover''' consists of sandbags, rock or slag chunks, trees, bushes, animals, some types of furniture and structures, and virtually anything else that a character can shoot over. Low cover does not provide as high a chance of stopping projectiles as high cover, but it's still far better than nothing, and it allows your colonists to shoot over it whereas a wall could block your shooters' line of sight to target completely.<br/>
High cover is something that you can lean around to shoot, low cover is something you can shoot over.<br/>
+
'''Natural cover''' is anything that can protect you on a newly generated map.<br/>
Natural cover is anything that can protect you on a newly generated map, artificial cover is anything you build, even debris that you move could potentially count as artificial cover.
+
'''Artificial cover''' is anything you build; even debris that you move could potentially count as artificial cover.
 +
 
 +
Cover is multiplied by a factor of 20-100% depending which direction the attack is coming from. Cover works best against attacks coming straight at it, but doesn't work so well against incoming attacks from the sides.
 +
 
 +
Here's a list of each angle threshold and the corresponding cover effectiveness multiplier in a list - as this doesn't look particularly great in a table:<br>
 +
*'''a < 15°''' = 100% effectiveness<br>
 +
*'''15° < a < 27°''' = 80% effectiveness<br>
 +
*'''27° < a < 40°''' = 60% effectiveness<br>
 +
*'''40° < a < 52°''' = 40% effectiveness<br>
 +
*'''52° < a < 65°''' = 20% effectiveness<br>
 +
*'''a > 65°''' = 0% effectiveness
 +
 
 +
Cover is additionally less effective at point-blank range: cover's only 33.33% as effective when the shooter is directly in front of the target's cover, and 66.666% if the shooter is 1 tile away from the cover.
 +
 
 +
Sometimes multiple sources of cover also work together to block additional projectiles. For example, shooting at a pawn behind low cover from a diagonal angle will result in 2 units of low cover providing protection at once, each at a reduced efficiency.

===[[Mountain walls]]===
+
=== Walls ===
[[Mountains]] are a brown rock structure that you can mine into.
+
Solid walls in general, from mountain walls to walls of ruins scattered across the map, are all capable of providing good cover.
The corners of the mountains are effective cover if the raiders come from the right angle. If they come from the wrong angle it can easily become a [[Death_trap|death trap]].
+
Pawns using walls as cover will fire from behind the corner of the wall.
  
=== [[Rubble]] ===
+
Walls provide up to 75% cover, but is heavily affected by direction.
[[Rubble]] is littered all over the map and will be used by attackers to gain an advantage over you. You can also use rubble for protection, but the random rubble placement is unlikely to favour you, so it's advisable to use it as a last resort

=== Rubble ===
(New Alpha version)
+
[[Rubble]], in the form of rock chunks and steel slag chunks, is littered all over the map and will be used by attackers to gain an advantage over you. You can also use rubble for protection, but the random rubble placement is unlikely to favor you, so it's advisable to use it as a last resort only.
* First place the turret blueprint
 
* Then drag a dumping zone around the turret
 
* Designate the desired amount of rubble to be hauled
 
* Wait for the rubble be hauled
 
* (optional, leave a 1x1 empty space next to the turret where a colonist can repair it while still being in cover)
 
  
 +
Rubble, in combination with a dumping area, can provide a free alternative to sandbag emplacements in the early game when Metal is scarce. Here is how it works:<br/>
 +
* Create a Dumping zone in the desired shape. (Typically a 1 square thick wall)
 +
* Designate the desired amount of rubble to be hauled.
 +
* Wait for the rubble to be hauled.
 +
* Place Colonists behind the wall for cover during a firefight.
  
(Old version, what version number?)<br/>
+
Rubble provides 50% cover, while Sandbags provide 65%, so it's advisable that you switch to Sandbags when you can afford them. Enemies can also use rubble to their advantage.
First designate a dumping area where you want your turret to be, then mark 16 rocks to be hauled to the area, when it is filed sell the dumping area and mark the middle 4 rocks to be hauled again but to another dumping area (designate a new area somewhere if you must), then build a turret inside the resulting square of rocks.
 
  
Rubble provides 40% cover.
+
=== Bushes ===
 +
Bushes provide 25% cover. In general, you'll want to avoid these -- especially as they can catch fire very easily.
  
===[[Bush|Bushes]]===

 +
 
 +
They provide 35% cover.
  
===[[Animals]]===
+
=== Animals ===
A last resort to cover if you have nothing else can be animal(s), by having animal(s) between your colonist(s) and the attackers, they can actually work as a makeshift cover by being hit instead of your colonists. (I learned this from personal experience, when a squirrel got in the crossfire and got hit from a raiders [[M-24]] bullet, and instantly died which means the squirrel was a one time cover).
+
A last resort to cover if you have nothing else can be animals. By having animals between your colonist(s) and the attackers, they can actually work as a makeshift barricade (or 'meat shield') by being hit instead of your colonists. Larger animals (eg. [[Muffalo]]) work better for this. However, you shouldn't rely on this, as animals tend to wander off at random. They can, however, become enraged and attack your enemies (or you) if fired upon long enough, so there may be something to it after all.
  
===[[Darkness]]===
+
===Pawns===
Darkness will not stop bullets (obviously) but it will increase the miss chance.
+
Other pawns can be used to shield your colonist from fire if they are in between them and the attacker. This is a natural shield when going up against a brawler that is backed up by a ranged attacker as their allies will accidentally hit them. Putting one colonist in front of another will also be used as a meat shield for the one behind. A downed pawn can provide cover as long as they're still alive, but once they die they lose the ability to soak up projectiles.
When in a firefight it helps to keep your colonists in the darkness while the enemies are in light areas.

[[Sandbags]] are the easiest and cheapest method of protection, offering substantial survivability potential while maintaining maximum angles of fire -- great for turrets and any shooters that need to cover a wide area of approach.

Sandbags enclosing a turret make a great attack point But keep the turret repaired, as it will explode when destroyed and can damaged nearby characters, a good practice is to leave a 1 [[tile]] gap (or make it a hole with sandbags on the back of the tile too) in the back (most protected side) where a colonist can stand and repair the turret and still be mostly in cover, but be prepared to make the colonist run away when the sparks begin to fly from the turret.

Cover can be anything that has the possibility to stop a fired bullet from hitting the intended target. Cover in RimWorld can be found in several forms. Some examples are: Rubble, Sandbags, Walls, the Saguaro cactus, and even animals.

High cover consists of any wall, constructed or otherwise, which a character can lean around to shoot enemies (if they're standing next to the wall). Any wall counts as high cover, and will stop bullets or other projectiles not just from hitting whoever is taking cover behind them, but prevent them from continuing on to hit anything else. It also blocks explosives.
Low cover consists of sandbags, rock or slag chunks, trees, bushes, animals, some types of furniture and structures, and virtually anything else that a character can shoot over. Low cover does not provide as high a chance of stopping projectiles as high cover, but it's still far better than nothing, and it allows your colonists to shoot over it whereas a wall could block your shooters' line of sight to target completely.
Natural cover is anything that can protect you on a newly generated map.
Artificial cover is anything you build; even debris that you move could potentially count as artificial cover.

Cover is multiplied by a factor of 20-100% depending which direction the attack is coming from. Cover works best against attacks coming straight at it, but doesn't work so well against incoming attacks from the sides.

Here's a list of each angle threshold and the corresponding cover effectiveness multiplier in a list - as this doesn't look particularly great in a table:

  • a < 15° = 100% effectiveness
  • 15° < a < 27° = 80% effectiveness
  • 27° < a < 40° = 60% effectiveness
  • 40° < a < 52° = 40% effectiveness
  • 52° < a < 65° = 20% effectiveness
  • a > 65° = 0% effectiveness

Cover is additionally less effective at point-blank range: cover's only 33.33% as effective when the shooter is directly in front of the target's cover, and 66.666% if the shooter is 1 tile away from the cover.

Sometimes multiple sources of cover also work together to block additional projectiles. For example, shooting at a pawn behind low cover from a diagonal angle will result in 2 units of low cover providing protection at once, each at a reduced efficiency.

See: complete list of objects that provide cover

Natural cover

Natural cover is anything that is generated when the map is created, and is almost everything you can find on a newly generated map.

Walls

Solid walls in general, from mountain walls to walls of ruins scattered across the map, are all capable of providing good cover. Pawns using walls as cover will fire from behind the corner of the wall.

Walls provide up to 75% cover, but is heavily affected by direction.

Rubble

Rubble, in the form of rock chunks and steel slag chunks, is littered all over the map and will be used by attackers to gain an advantage over you. You can also use rubble for protection, but the random rubble placement is unlikely to favor you, so it's advisable to use it as a last resort only.

Rubble, in combination with a dumping area, can provide a free alternative to sandbag emplacements in the early game when Metal is scarce. Here is how it works:

  • Create a Dumping zone in the desired shape. (Typically a 1 square thick wall)
  • Designate the desired amount of rubble to be hauled.
  • Wait for the rubble to be hauled.
  • Place Colonists behind the wall for cover during a firefight.

Rubble provides 50% cover, while Sandbags provide 65%, so it's advisable that you switch to Sandbags when you can afford them. Enemies can also use rubble to their advantage.

Bushes

Bushes provide 25% cover. In general, you'll want to avoid these -- especially as they can catch fire very easily.

Trees

Trees provide 25% cover. Prior to Alpha 17, they provided 43%.

Saguaro cactus

It's a large tree-like cactus with 2 branches. See this page for a picture.

They provide 35% cover.

Animals

A last resort to cover if you have nothing else can be animals. By having animals between your colonist(s) and the attackers, they can actually work as a makeshift barricade (or 'meat shield') by being hit instead of your colonists. Larger animals (eg. Muffalo) work better for this. However, you shouldn't rely on this, as animals tend to wander off at random. They can, however, become enraged and attack your enemies (or you) if fired upon long enough, so there may be something to it after all.

Pawns

Other pawns can be used to shield your colonist from fire if they are in between them and the attacker. This is a natural shield when going up against a brawler that is backed up by a ranged attacker as their allies will accidentally hit them. Putting one colonist in front of another will also be used as a meat shield for the one behind. A downed pawn can provide cover as long as they're still alive, but once they die they lose the ability to soak up projectiles.

Artificial cover

Artificial cover is anything that you can build. (In a sense, rubble could be counted as artificial cover after you have moved it, and are using it as cover.)

Sandbags

Sandbags are the easiest and cheapest method of protection, offering substantial survivability potential while maintaining maximum angles of fire -- great for turrets and any shooters that need to cover a wide area of approach. U-shapes are good for one character to hide in. Zigzag patterns will allow multiple characters to cover close together, which is handy if you want to focus fire on a few attackers.

Sandbags enclosing a turret make a great defensive hardpoint. But make sure to keep the turret repaired, as it will explode when destroyed and can damage nearby characters and structures.

Sandbags provide 65% cover.

Walls

Walls can be used as cover as well. Characters will lean around them to shoot. Three wall blocks placed diagonally make a great sniper nest. Natural walls work in the same way, and will almost always have more durability than any artificial wall.

Door

A door can be used as a high cover if it stands alone so a colonist can lean around it.
