Triaxos (UK) (1987) - Amstrad CPC - Action, Sci-Fi

A mind probe has been sent to the high-security prison Triaxos to retrieve information about a prisoner who is the only man capable of activating the most powerful weapon in the galaxy. You have landed in the prison 10 minutes before the probe to find and return the man to your ship within 30 minutes. You must search the prison by destroying the robot guards and exploring each room. The floor of each room is anti-gravity, so you can stand up to use the other exits on any wall. Some of the exits are hidden, but the map of each room shows the location of the exit. You'll need to find a Jet-Pack for the prisoner, a key to control the prison's defences and a weapon to destroy the mind probe. You also need to locate the communications room to call your ship.
