use your mouse to turn your character up, down, left, and right. Hold down the left mouse button to shoot bullets at the zombies, the farther your mouse is from the crosshair, the faster you turn. Use WASD to move around, sorry if it's a bit buggy. More updates coming soon!!!!!! if the turning stops working, try centering your mouse cursor on the white box crosshair and playing around with it. If that doesn't work, try refreshing the game. Also press the space bar to jump.
