Click to fire, hold to go Rambo, R to reload when you run out of ammo, and WASD to move. The bullets may not be a hundred percent accurate, but that's the point: in real life, bullets don't always fly straight. The crosshairs are also kinda weird.
Before you ask, yes, this game will be a shooter. With real bullets and real (at least, somewhat real) guns. No blood or gore, though, I mean come on, this is Scratch. "It's been a LONG time... How have you been? I've been REALLY busy making this preview..." Also, the sound effect I chose might be kinda weird. Sorry.
