At first you start with a 30 round magazine, but after that you onky have 10 round mags. Use the mouse to point and shoot the horde of zombies coming for you. You can only hold 10 bullets at a time - when you run out of bullets, you should press the spacebar to reload. This will take 3 seconds, so be careful! Note that you can't reload if you still have bullets.
I remixed this because I wanted to make it even cooler. All credit goes to amylaser for the original game.
