I'm trying to remember the name of a PC game I played years ago (and I mean years ago, probably about 1998, give or take a year, and it might have been two or three years old then). I don't remember much about it, but it ran on a Windows 95 PC, so it could have been either DOS or Windows, and it was a first person shooter, and it started off in a space-craft hanger (or similar). I can't remember if you were on foot or in a space craft/vehicle when you started the game (if was first person, definitely), but the hanger, or whatever it was, had solid platforms that you went up small ramps to mount, and you were free to wander at will around this hanger, as though it was an area in any other first person shooter.

I can't remember for definite anything else about it, as I'm not sure if I'm confusing games like Alien Trilogy or Mace Griffin with my memories of the rest of this game, but everything I wrote in the first paragraph is definitely in this game. Sorry to be so vague, but it was such a long time ago.

Thanks for any answers.
