Prepare for horror and fright beyond your wildest nightmares, as you step into the world of ALIENS: Thanatos Encounter. The terrifying creatures made famous by the popular ALIENS movies come to Game Boy Color in a totally new adventure. You play as one of five space marines who are sent to explore an abandoned freighter. Naturally, the situation is far worse than your squad expected: the ship is completely infested with thousands of vicious aliens. In this single-player shooter, you'll make your way through the various sections of the ship in 12 missions. Discover the solution to the mystery of the aliens' reappearance through the cinematic cutscenes you'll see throughout the game. You can use a variety of alien-busting weapons like machine guns and flame-throwers to fend off the incoming horde and, if all else fails, turn tail and run as fast as you can! Battle a wide variety of different breeds of aliens, including some all-new hybrids. ALIENS: Thanatos Encounter is compatible with Game Boy Color only.
