A mechanoid commander designed to coordinate and motivate other mechs during long extermination campaigns. Its most obvious power is its ability to resurrect recently-killed mechs by supercharging their self-repair processes. Less obviously, it is intelligent and psychically present, radiating hatred into the minds of anyone in a wide radius.
While all mechanoids have a dim psychically-present intelligence, only the apocriton and a few others truly feel hatred for their victims and understand the suffering they inflict.

Am apocriton is a mechanoid added by the Biotech DLC.


As mechanoids, every apocriton is immune to fire, Flame and Heat damage, toxic buildup, and temperature extremes, despite having Comfortable Temperatures defined. They do not need to eat, rest, and have no mood. They will be stunned by EMP attacks for a time proportional to the EMP damage inflicted and will "adapt" and rendered immune to further EMP strikes for 2,200 ticks (36.67 secs). It has 80% EMP resistance, so EMP attacks stun it for 80% less time.

Along with termites, apocritons are the only mechanoids that can't be gestated by your colony.

As an enemy

You can summon a hostile Apocriton with a mechanitor and a mechband dish, destroying the dish in the process. Therefore, summoning one requires the High Mechtech research. However, they are not exclusive to summoning, as strong enough mechanoid raids may feature one.

The apocriton carries a long-range toxic needle gun and is accompanied by other mechanoids. It has the ability to resurrect fallen mechanoids, induce negative moods in humans on the map, and jump long distances. Apocritons will spawn with a heavy shield unit, which has a strength of 400%.

Apocritons can resurrect any[Colony mechs?] mechanoid within a 9.9 tile radius that has been dead for less than 3,600 ticks (1 min). This ability does not require line of sight, meaning it can resurrect mechs behind walls. There is a short ? warmup before the mech arises.[Detail] There is a 480 ticks (8 secs) cooldown after each resurrection before the ability can be used again. An apocriton start with 30 "charges" to use this ability when spawned. Resurrecting a Light class mech costs 1 charge, resurrecting a Medium class mech costs 3 charge, and resurrecting a Heavy class mech costs 5 charge.[Super heavy?]

It is also capable of leaping to any tile within a 9.9 tile radius, outside a 5.9 tile radius and within line of sight. Therefore, it can jump over rock chunks and fences, but not walls. There is a short 30 ticks (0.5 secs) warm-up before jumping. It cannot be hurt mid-jump, even by explosions directly under it, but can still get hit during a short warm-up before jumping. There is a 480 ticks (8 secs) cooldown after each jump.[Verify] Apocritons will jump when confronted by a melee enemy.

The negative thoughts[Detail] inflicted by the apocriton covers the whole map, and is scaled by psychic sensitivity like a psychic soothe and psychic drone. Though this effect has a long range, the value of the debuff is also affected by the pawn's distance to the apocriton. If the distance is 5 tiles or shorter, the pawn receives a −16 mood debuff, if the distance is between 5 and 12 tiles, the pawn receives a −10 mood debuff, and if the distance is greater than 12, the pawn receives a −4 mood debuff.

Defeating a hostile apocriton will drop a nano structuring chip. This can be used to research High Mechtech and Wastepack Atomizer.

Like the other mechanoid bosses, after being summoned 8 times, the next summon will be the same as wave 3.


? The mysterious apocriton is an intelligent commander mechanoid and psychic warrior that harbors endless hatred for humanity. Not much is known about it, except that its psychic powers poison the human mind with rage. Its weapon is hatred.

Much smaller and less durable than the other mechanoid boss units.

This is it! The final Biotech boss fight! If you managed to find victory over the brutal war queen, apocriton shouldn't give you much trouble. The first Apocriton summon spawns with several scythers and militors. and has the ability to revive them. However, all of these units have tiny attack range! You can just stand back and destroy them over and over with gunfire. Like the war queen, apocriton can only use its abilities for 30 times. Its 400% heavy shield unit can be hard to break using ranged attacks, and it is harder to kill it using melee since it can disengage from melee combat using its leap ability. If you are unable to take it down quickly, prioritize on killing weaker mechanoids such as the militors so the apocriton wastes its ability.
