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.
Extinction is when all members of a particular group die. Most often, we use it to discuss animal species. Many fear that the tiger is headed for extinction because of development and hunting. People are still trying to figure out what caused the extinction of the dinosaurs: many think it was because of an asteroid. When people cut down rain forests, it can lead to the extinction of many species. Although extinction can be natural or unintended, the word can also mean forced, planned killing.
