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, Orbital/Air strikes, grenades thrown into either of the 2 vents open above the door the Troopers exit from, or the door itself when it opens to release more Troopers.

Tactics

 * Explosive weapons are useful for taking out Automaton Fabricators from a distance; one shot aimed at the fin above a vent can destroy them and save your grenades for other situations. Shooting the fin will cause the projectile to ricochet downward into the open vent and destroy the Fabricator. This must be done while facing toward the front of the vents, as trying this from an angle to the side will cause the ricochet to go elsewhere.
 * The SPEAR will destroy fabricators with one missile from any direction, but must have clear view to the center of the object before it will lock on and fire.
 * It can be difficult to take out Fabricators with impact grenades, as you must precisely aim it into the vent without hitting the trapdoor.
 * Aim the impact grenade at the lower lip of the vent. It will actually go slightly higher, and enter the fabricator.
 * The Orbital Laser Strike is useful for taking out Fabricators in Heavy outposts as the laser will target them first before moving to ground units.
 * If in a dire situation, Hellpods like reinforcements, advanced weapons or resupplies can be used to take out Fabricators by throwing the beacon right at the base of the Fabricator.
 * Eagle payloads such as the standard Airstrike and the 500kg Bomb are great ways to take out multiple Fabricators in close proximity to one another with a single strike.
