Automaton Fabricator

The Fabricator is an Automaton structure that periodically spawns Troopers of any kind until destroyed. Much like the Terminid bug hole the Fabricator must be taken out with explosive weapons or grenades thrown into either of the 2 vents open above the door the Troopers exit from.

Tactics

 * The AC-8 Autocannon is useful for taking out Automaton Fabricators, one shot aimed at the trapdoor above a vent can destroy them and save your grenades for other situations. Shooting the trapdoor will cause the projectile to ricochet off downward into the open vent and because of this, the player must shoot the trapdoor parallel to the front of the Fabricator as this cannot work when aimed from the side.
 * It can be difficult to take out Fabricators with impact grenades, as you must precisely aim it into the vent without hitting the trapdoor.
 * The Orbital Laser Strike is useful for taking out Fabricators in Heavy outposts as the laser will target them.
 * If in a dire situation, Hellpods like reinforcements, advanced weapons or resupplies can be used to take out Fabricators by throwing the beacon right next to them.
