The death animations are horrible. The human enemies that got hit with the shotgun hardly ever reacted to it, no sparks, blood, smoke puffs, marks or even a twitch by the blast, it looked like nothing hit them, then suddently they tip forward dead. Just looked cheap.
If you are 5 feet from someone with a shotgun and you fire, they shouldn't act like a solid rock pillar, perfectly still. Elite Force 2 even got that right.
The video quality was too low and small to get a good impression of the graphics. I think it's time everyone starts using the bink format, or anything that gives a clear true look at the game as Valve has done.
