Star Trooper (UK) (1988) - Amstrad CPC - Action

An alien syndicate led by Jabba McGut has stolen the Earth's only supply of 25 extra-special alloys, and is now threatening life on Earth. Only a Marine Corps Star Trooper such as you will be tough enough for a mission as dangerous as this. It is your aim to recover the alloys and return them to Earth. There are five missions with five alloys of the same colour to recover in each one. You must wander around a labyrinth of corridors and lifts to find the alloys, while shooting the aliens that patrol the labyrinth. You'll also have to find keys to let you pass through force fields and use the teleportation units.
