Phantom Exterminator

Phantom Exterminator is an achievement/trophy in Call of Duty: Ghosts gamemode Extinction. It was introduced in the map Nightfall in the Onslaught DLC. It requires the player to kill 5 Phantoms in one game. The achievement does not specify if it has to be in Nightfall, but since Nightfall is the only map out currently with Phantoms we will just have to wait and see.
