Control your soldier, the only one who can keep evil creatures from taking over the world. To move your character around, use the W, A, S, and D keys. You can only see a little bit around him because of the lighting situation. To see more, move your mouse in the direction you want to aim your weapon. This will also light up the area that you are pointing your gun at. To shoot, click your mouse. If you have multiple weapons, you can switch between them by pushing Q and E. Kill creatures to earn money, which you can use to upgrade your weapons.
