This game is so similar to the Alien movies in graphical style and plot that I completely refuse to believe that it wasn't intended to be Alien in the beginning. Anyway, taking the role of a seriously endangered alien, you've got to wander around an 'enormous' (142 screens) ship, collecting pods and plopping them into an incubator unit.
All that you seem to do throughout the game is wander through the corridors (which, it has to be said, are rather attractively laid out) spitting a mouthful of acid or two at the numerous aliens which wibble around along the floor and picking up the odd pod as you come to it. The gameplay is very much tried and tested, involving left, right. Fire and jump, and the trip in the occasional lift.
This may not sound particularly exciting and, well, it's not really, because despite the rather pleasing graphics and the fact that you get to wander around spitting acid at things, it's really only a rather tedious exploration.
Survivor is disappointing, despite being professionally programmed, exploiting none of the opportunities its plot offers to the full. Nothing new here.
