The AA Gun is the Survivors anti-aircraft turret. It is used by Will Grey to defend The Ark against Watcher Flying Discs, Watcher Knights, and Archons.

The AA Gun has four barrels, firing one barrel approximately every second. This makes it a fairly slow gun, but what it packs in firepower more than makes up for that shortcoming.

The AA Gun also has a zoom feature that is very useful for taking out the weak spots on an Archon's legs.
