The developers at 2K Marin working on The Bureau: XCOM Declassified say that they're going to be throwing serious challenge at you. And from what I played a few months ago, this 1962-set prequel to last year's hit release isn't the kind of game that you just coast through. Good thing this newest trailer covers some of the tactics and abilities that you'll be able to wield in your fight against extraterrestrial Outsiders. You're not getting any hints about how the story's going to unfold in this clip. But if you still had questions about camera angles, encounter space layout and enemy classes, you'll get more insight on all of that here. If that's not enough, head over to the game's Facebook page for a 12-minute gameplay video.
