Call of Duty got away with putting zombies in mah FPS. They faced no consequences. Now they've put aliens in mah FPS. For my money, aliens > zombies anyway, so I'm good.
Extinction tells the tale of these aliens over the course of 4 parts. Part 1 is part of the Call of Duty: Ghosts's Onslaught DLC. It's called Nightfall and there's a trailer for it.
It's set in a remote Alaskan military research center, because where else could they set it?
