The trailer is like the usual reveal of Call of Duty by showcasing the story side first. We do have confirmation though! The game will release in November, plus there is a online beta coming soon for PS4, Xbox One, and PC. (It notes all platforms are not confirmed.) We could see it come to Nintendo’s WiiU, or even last generation, but so far it’s nice to see that it’s exclusively a “next generation” COD.
You can head to the official site to see what retailers are included in the beta promotion. To answer early questions, no it is not exclusive to GameStop.
The game seems to stay in the “future” timeline, and has a bigger emphasis on “exo suits” by making the entire soldier a weapon. There is also zombies in the game!
