A legionary is a mechanoid added by the Biotech DLC that projects a shield.


Legionarys can be gestated by a mechanitor at a Large mech gestator once the Ultra mechtech research project has been completed. They require Plasteel 100 Plasteel, Component 6 Components, High subcore 1 High subcore and 4 gestation cycles taking 1,800 ticks (30 secs) each to initiate. They take up 2 bandwidth from their linked mechanitor.

Dead, friendly legionarys can also be resurrected at the large mech gestator using the "Resurrect medium mechanoid" bill. This requires the corpse of the friendly Legionary, Steel 50 steel, and 1 gestation cycle taking 1,800 ticks (30 secs) to initiate.


As mechanoids, every legionary is immune to fire, Flame and Heat damage, and temperature extremes, despite having Comfortable Temperatures defined. They have 100% Toxic Resistance and Toxic Environment Resistance, making them immune to toxic buildup, rot stink and other toxic effects. 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).


The legionary projects a shield that is 3 tiles in radius, which is visible whenever drafted or attacked. The shield stops all incoming ground-level fire from passing into the bubble except that fired by the member's of the legionary's faction,[Turrets?][Allies?] be it mechanoid hive or the players. It does not prevent pawns of any faction that are inside from firing out. Also note that this only applies to ground-level fire, i.e. fire from ranged weapons carried by all types of pawn and turrets, including grenades that cross the boundary of the shield. Explosives not fired will detonate on the shield edge. Fire from mortars, orbital bombardment, or aerodrone strikes or salvos Content added by the Royalty DLC will not be blocked by the shield, nor will explosions crossing the boundary.

The shield can absorb up to 200 damage before breaking. If an attack would be sufficient to completely deplete the shield's charge, then the rest of its damage is negated, and the shield is temporarily broken. The shield regenerates charge at rate of 0.25 HP per second, so long as it has not been broken.[Delay?] However, once the shield's charge is completely expended, the shield will break and be totally disabled for 5,400 ticks (1.5 mins) after which point the shield will be restored at full health. Projectiles from EMP grenades and launchers from outside hitting the shield will disable the shield for 1,500 ticks (25 secs), after which time the shield will be restored at full health. Furthermore, unlike the mechanoid itself, the shield projector will not adapt to the EMP effect. Its therefore possible to continuously disable the shield until the mechanoid can be killed. Note that an EMP area of effect overlapping with the projected shield will not disable it - a projectile must hit the shield or the EMP damage must be dealt to the structure itself

If the EMP damage is dealt to the legionary itself, the shield is similarly disabled[What time?] but will continue to regenerate as if it was not.

A pawn does not need to be inside the shield to benefit from the effect, assuming the enemy is not inside the shield and that the shield is between them and their attacker the incoming rounds will be stopped. However, it does not prevent pawns from moving inside the shield and attacking.

As an ally[edit]

Mechs under player control require power: legionaries use 10% of their power per day while active. If set to dormant self-charging, they instead recharge for 1% power / day, without pollution. They recharge in a large mech recharger (400W), for 50% power/day, creating 10 wastepacks whenever the recharger's waste is filled up.


Legionaries use the needle launcher, a shorter range version of the needle gun.


As an enemy[edit]

  • The launcher is weak, but don't underestimate it. It's still strong enough to destroy vulnerable organs, including the brain.
  • EMP works well to break the shield, if you can get close enough at all. Legionaries are often surrounded by powerful mechanoids due to their advanced nature.

As an ally[edit]

The Legionary's shield provides a safe space for your ranged pawns to attack the enemy without worrying about retaliatory fire. With 200 hitpoints, slow firing weapons like pila, sniper rifles, and charge lances will no longer trouble your pawns as their slow fire rate gives the shield a bit of time to regenerate. However, care should still be utilized when relying on its shield. Exposure to rapid-fire weapons like miniguns or heavy charge blasters (both found on Centipedes) can shred the shield extremely fast.

As a projected momentum repulsor field, the Legionary's shield is vulnerable to EMP, so try to take out enemies who wield EMP grenades or launchers first.

Both shield mechanoids, the centurion and the legionary, are named after positions in the ancient Roman Army. The Roman Army famously used large shields called scuta.
