Alien Abduction

Alien Abduction is a side-scrolling shoot 'em up. The player controls a spaceship that must fight its way through alien ships. Crystals held by some of these aliens must be collected in order to advance. The player-controlled ship can shoot the enemies with firearms or drop nuclear bombs. The player receives three such bombs at the beginning, but using them does not increase the score. Power-ups such as weapon upgrades, shields, and invisibility are also available.
