left click to fire auto rifle. it IS automatic, so you can hold down the mouse button to enable rapid fire mode. move your cursor to the bottom of the screen to crouch. just point your cursor up again to stand back up. to play, just click when you are at the main menu.
credit to deadtrigger for the automatic rifle. credit to google images and the call of duty series for the germans, and the menu., also the big readout at the top shows how many hits on enemies you have. not your kills. so if it says like 350, but you only killed a few germans, dont freak out thinking its a bug.
