Your mission in this addictive shooting game is to use your two guns wisely to destroy the aliens. Keep them together for a single shot, or split them and catch enemies in the crossfire. Protect the pipeline from the mining lasers. Hitting enemies from two sides causes double damage and earns bonuses. Use LEFT and RIGHT ARROW KEYS to move around the outside of the screen. Press UP or DOWN ARROW KEYS to toggle SPLIT or GROUPED mode. Press SPACEBAR to shoot. Good luck!
