50% of the trailer is a lie
Nearly all the awesome action you see in the trailer is part of the 5 minute opening montage, like that part with Vanderohe using the big saw and all the bombs dropping, and all the chaos in the streets.
And then that cool scene at the end of the trailer with all of them in a circle with weapons as a huge horde is coming at them thats not even apart of the movie really its a fantasy scene that they're seeing in their heads as they're going over the plan.
