The ARK (also spelled Ark) is a barrel attachment found in the Extinction maps "Awakening" and "Exodus". It allows weapons to turn into a "laser weapon", though it still uses conventional ammunition and also has the additional effect of causing extra damage to cryptids, which further makes any that are killed with the weapon it's attached to explode in a similar fashion as to the Pipe Bombs.
It is found randomly in hidden rooms around the map and mounted on a dead soldier's unusable Ameli. Only one can be found randomly in each area (except in the last area which contains two) so a total of four ARK's can be found and attached per match.
It replaces the Muzzle Brake if there is one attached to the firearm. However, unlike barrel attachments in other game modes, the ARK (as well as the Muzzle Brake in Awakening) can be used on weapons that have an integrated silencer.
The Nemesis DLC added a Teeth upgrade that makes the ARK available to handguns as well; it replaces the Muzzle Brake on the player's upgraded handgun. It also added an upgrade that allows the player to scavenge the ARK from Search Piles in all maps.
The ARK can be attached to all weapons available in Extinction, except the Honey Badger, which was removed along with the addition of the ARK to the maps in which it was available, and launchers and specials.
