Your mission in this most intense flash shoot em up ever is to join four heroes as they blast across the solar system and destroy all invading Alien forces. You can also bring your buddy for a Two-player simultaneous play. Use YOUR MOUSE to move and click LEFT MOUSE BUTTON to shoot. Try to destroy all enemies and avoid being hit by them. After defeating a mini-boss, or before a major boss, you will reach a checkpoint. If you die, the game will resume from here. If the game runs slowly, you can press "L" KEY anytime to lower the visual quality. Enjoy the game!
