In this awesome space shooter game, your aim is to control your space ship and shoot down all of the space crafts in enemy fleet, and then destroy their big boss at the end. Be sure to collect different weapon upgrades and power-ups on your way and keep your eye on your health status. Use ARROW KEYS to control your ship, press SPACEBAR to fire. Hit SHIFT KEY to activate drone (if vailable), and hit CTRL KEY to activate shield (if available). Good luck!
