A game I probably played in the early 2000s, but it I think it was from the mid/late nineties. I think it was bundled as a demo with some kind of robocop game and a demo of Total Annihilation, but don't quote me on that. You were in something like a spaceship, it flew, and it was black I think, and angular, but it was first person. but you were underground I think. There was a bit you went through that said "no humans beyond this point" or something similar. You could collect powerups and stuff and when you died, you could respawn and find where you died before and pick up your powerups from the last time (which I thought was genius at the time). I also seem to recall everything being very brightly coloured, but again, don't quote me on that.
