A game I desperatly wished we had a sequel to. The Story was pretty good and ends on a cliffhanger that could've lead to a Ghosts 2. The multiplayer was fun for what It had and it even had its own version of Levelution. But the cherry on top was the Extinction mode, esentially "COD Zombies but the zombies are aliens" with a bit of a storyline. If this can come to GOG, that would be awesome.
