A cover system would slow the game down I think.

Yeah, I read a few reviews and the general consensus is the AI should all be hired as quarterbacks. Haven't played solo much myself.

I reckon this is sweet, and pretty realistic too. Bullet damage is reduced after passing through objects, but in multiplayer its awesome running around with bullets literally going everywhere, or to pepper a wooden house you know a couple of guys are hiding in with a LMG.
