Freaking nice trailer. I didn't re-watch game trailers as many times as this before. What i feel is that game trailers usually exaggerate the game play. But for this, the fights(1:46 - 2:20) aren't. Just some changes in the camera angle so it look awesome. And it actually shows one of the most important aspect of the game -teamwork. Thumbs up for the guys who did this trailer.
All hail OS~
