A '''tunneler''' is a [[mechanoids|mechanoid]] added by the [[Biotech DLC]].

== Summary ==
{{Mechanoid Summary}}

Tunnelers do not seem to spawn in regular mech [[raid]]s, [[crashed ship parts]], or [[mech cluster]]s{{RoyaltyIcon}}.{{Check Tag|Verify|Not thoroughly checked}} However, they appear as part of certain [[apocriton]] summon groups.

=== Combat ===
In combat, tunnelers use blunt melee attacks. They have an innate [[smokepop pack]] ability, but this has a cooldown of 15 days.

Tunnelers have the highest armor values of any mechanoid in the game, with {{+|5%}} more Sharp and Blunt armor than the [[war queen]]. However, with a health scale of 1.52, it doesn't have the hit point pool of the larger mechs. They have an innate shield, which is equivalent to a [[shield belt]], just with 250 HP. This is higher than even a legendary [[quality]] shield belt.

Uniquely, tunnelers are staggered by any ranged projectile that hits it - regardless of its stopping power. Instead of the usual {{ticks|95}} stagger time, tunnelers are slowed for {{ticks|120}} per hit, though tunnelers move slightly faster than a "usual" stagger. This stagger is caused even if the bullet hits the shield, or if the bullet's damage is negated entirely by armor.

== As an ally ==
Tunnelers are a heavy mechanoid, and require [[Research#Standard_mechtech|Standard Mechtech]] to create. They are created from a [[large mech gestator]] with {{Required Resources}}, taking up 3 [[bandwidth]] from a [[mechanitor]]. Then, they must gestate for 4 [[gestation cycle]]s to be made. Once made, they recharge in a [[large mech recharger]] (50% power/day), creating 15 [[wastepack]]s whenever the recharger's waste is filled up. When killed, friendly tunnelers can be resurrected for the cost of {{icon small|steel}} 75 [[steel]], so long as the corpse is extant.

=== Work ===
Tunnelers will do tasks associated with the Mining tab, though are unable to use [[deep drill]]s. They cannot be manually controlled, except when drafted for combat. They have an effective Mining skill of 10, but with a [[Global Work Speed]] of 150%. 

For reference, every other labor mechanoid has a Global Work Speed of 50%. As [[control sublink]]s and the Mechanoid Labor [[precept]]{{IdeologyIcon}} both act as additive offsets to work speed, the tunneler receives a relatively smaller boost. For example, a [[cleansweeper]] could go from 50% to 70% work speed - a {{Good|x140%}} increase. A tunneler would go from 150% to 170%, which is only a {{Good|x113.3%}} increase.

== Analysis ==
Tunnelers are useful for mass mining operations, whether it is expanding out your mountain base or mining mineral lumps found using a [[long-range mineral scanner]]. Mechanoids are not subject to illness or mental breaks, and only recharge for 2 days out of every 12. 

=== Work Speed ===
{{recode|section=1|reason=Add the actual mining speed stat of the tunneler to the table below, to allow for direct comparison to human miners. If it is already in mining speed and work speed, convert language to reflect that}}
The following table summarizes the work speed effects of operating within the influence of a [[mech booster]] and having [[control sublink (standard)|control sublink]]s installed by the Mechanitor.
All values are for 50%+ lighting conditions.

A colonist's work speed is based on their [[Mining Speed]] stat. At about skill 13, a normal colonist with no traits or health conditions will mine as fast as a tunneler operating without a Mech Booster or Sublink bonus. A similar colonist at skill 18 mines roughly 97% as fast a mech-boosted Tunneler with no Sublink bonuses. Installing a [[Drill arm]] allows a Skill 5 pawn to mine faster than an unboosted Tunneler.{{Check Tag|Mining Specialist?}}

=== Mining Yield ===
Tunnelers appear to have no special modifiers to [[Mining Yield]], meaning that they function identically to a Skill 10 Colonist for this purpose. Higher skilled colonists will extract more material, but the increase isn't very large until very high skill levels. For comparison, a healthy, level 20 human miner has the maximum possible mining yield of 113% compared to the 102% of the tunneler. For maximum resources, leave ores for higher skill colonists, if present, to mine. However, it may be more useful to get a place dug out ''now'' then to get a little more ore.

Conversely, a lower mining yield will slightly lower the amount of [[stone chunk]]s that have to be hauled out of a mountain base. The difference is too small to notice, either way.

=== As an ally in combat ===
Tunnelers are incredibly slow, with middling {{DPS}} and a decent durability. They have 152% the health of a human, armor slightly worse than normal [[recon armor]], and an innate shield better than a ''legendary'' [[shield belt]]. While they won't deal as much damage compared to a dedicated melee pawn, nor able to run or lock down enemies like a scyther, tunnelers can draw enemy fire. This lets other combatants focus on dealing damage.

Tunnelers face competition from [[scyther]]s, a melee-focused mech also unlocked from [[Research#{{Q|Scyther|Required Research}}|{{Q|Scyther|Required Research}}]]. Tunnelers don't have a scyther's speed, and consume +1 [[bandwidth]]. However, they are significantly more durable, with significantly more armor, slightly higher health, and the aforementioned shield. The tunneler's {{Hover title|I.e. DPS after accounting for the melee verb system but without considering the target's attributes|base true DPS}} of 7.59 (4.71 after [[Melee Hit Chance]]) seems low at only {{%|7.59/10}} of the 10 (6.2 after Melee Hit Chance) of the scyther. However, tunnelers use [[Damage Types#Blunt|Blunt]] damage. Blunt attacks usually face far less armor than a scyther's Sharp blades.
*Against a normal [[flak vest]], the tunneler faces almost no DPS loss at all, while the scyther's DPS is more than halved.
*Against [[centipede]]s, the scyther is reduced to 70% of their DPS, while the tunneler's {{AP}} totally negates their blunt armor.
So, while the scyther still has superior DPS against most enemies, their damage output is far closer than it first appears. Blunt damage's superior damage propagation and overkill mechanics further help narrow the gap against enemies with health scales comparable to humans. If durability is completely irrelevant, such as when using [[Psycasts#Skip|Skip psycast]] {{RoyaltyIcon}} mobbing tactics, then scythers are superior due to their lower bandwidth cost.

[[Centipede]]s have {{%|{{Q|Centipede|Health Scale}}/{{P|Health Scale}} round 2}} the health scale and thus {{HP}} of the tunneler, slightly worse armor (Sharp: {{Q|Centipede|Armor - Sharp}}% Blunt: {{Q|Centipede|Armor - Blunt}}%), and no shield belt. They also have 86% of the {{Hover title|I.e. DPS after accounting for the melee verb system but without considering the target's attributes|base true melee DPS}}, cost 1 more bandwidth, and are unlocked at [[Research#{{Q|Centipede gunner|Required Research}}|{{Q|Centipede gunner|Required Research}}]]. For the sole purpose of tanking against melee enemies, the centipede is almost always better{{Check Tag|Verify|Increasing melee tank DPS can result in lowered enemy DPS due to injuries and significantly improves melee tank lifespans. 16% extra DPS and slightly better armor is probably not enough to overcome 2.9x the HP but needs in-game testing against common enemy types to confirm}} if they can be afforded. Their ranged weaponry also makes the centipede more flexible. However, lower melee DPS and lack of shield can be determental against mixed-range enemies. When a centipede is tied up in melee, unable to fire while being fired at, it will be worse (or at least, not much better) than a tunneler.
