Play as a brave soldier to defend your base! Use your space bar to zoom in on enemies and areas, allowing you to fire more accurately. You start with one weapon, but gain more as you go through the game. To switch between weapons, use the direction keys on your keyboard. Click your mouse button to fire your weapon at the enemy. As your enemies approach your palisade, try to kill them before they defeat the wall of your building and overrun it. Aim quickly and accurately to make the most of your ammo and keep your wall from suffering too much damage.
