Alien Syndrome (set 7, System 16B, MC-8123B 317-00xx) — About this game
Rescuing captives opens the exit to the stage’s guardian. A time bomb limits how long you have to explore and fight. Maps and better weapons help along the way, but defeating an enemy does not by itself complete the rescue objective.
