all weapons except:
-shotgun
-mini gun
are unlimited ammo as far as I've found but weapons do over heat or need reload time (tanks)
wall running is now possible due to super speed and i have heard the crack of the speed of sound while testing so running is now VERY quick
punching is now 8 times as powerful as normal that can punch a man off the map and destroy a car but for some reason showing and jumping has not changed.
final stealth is a slow count down running and jumping is ok but shooting still stops it
