Xenomorph

Released in 1990 I am not sure I would actually class this as an FPS although it appears in most lists - Its a RPG from a first person perspective and you move around using the buttons on the screen; I will give it the benefit of the doubt.

Your ship has become infested with aliens and you have to clear them out (how many games have copied that idea) it involves rooting about on your ship pick in up stuff and killing things etc etc.

No walkthru found.
