The combat in that video looked awful. I'm not sold on the idea of ammo at all; the original's lack of it was refreshing and was built into the game's universe. Weapon heat and the effects of various weapons mods on it presented a range of possibilites. I'd prefer they added more meaningful tactical and power related decisions than when to duck back and reload.

What was that nasty blue goo that kept appearing on the Shepard character? Please don't say alien blood. That would increase the cringe factor by a power of two.

Not fond of the new HUD either. The old one was much clearer in terms of giving information.
