Turn with the mouse, W to go forwards. 1/2/3/4 to select pistol/rifle/knife/mines. Kill the boss
This is still a little buggy. Bugs: You take damage from the boss when you knife him(?). You have to click the green flag twice before the game will reset. Sometimes, your bullet will start firing out of the wall, when you shoot, it will work normally, and then start again afterwards. This is based off an earlier game, zombie killer rampage. I removed it, because it was extremely laggy.
