Don't forget about the no sound from enemies until after you're dead, including them shooting their non-silenced weapon, and the fact that most enemies simply aren't there until you die or something. Killed by a tank right next to me. I mean sure maybe I was being blind but how did not ONE person in the game spot it? You know what it probably came out of my rear end since I was crouched, just slid on out there silently with no engine noises, no creaking, no foliage, just plopped right there on the ground and proceeded to shove it's cannon down my throat!
