First: Sniper's sound in gears 2. It sounds like when you shoot a piece of cream out of a toothpaste. I mean the shot sounds weak. Sniper's sound in gears 1 is much better (Agree?).
Second: Weapon sliding. I think it is epic's purpose (not a glitch) because weapon sliding helps you avoid receiving bullcrab headshot. It takes you a little while to pick a gun up, so you have to stay at a same spot for a few second; and during that time, you become a perfect target for head-thirsty snipers, weapon sliding is the best choice to avoid those marskmans. (any idea).
