Space/Click to Fire R/Click to Load/Reload Ha! Bet you tried to fire it immediately! Nope, don't keep firearms loaded, so press R/Click THE PING! Scratch team, if/when you see this, it is not meant to be violent.
Added arms (from @Dinofan13), environment, background noises, randomized the casing direction (in front or behind), showed the ammo count, and changed ping direction. Yeah, I like the M1 Garand, the better question is, why DON'T YOU like the M1 Garand?!?!?!
