The 3do had some duds in it's time, but this game out shinned by breaking the mold fo the FPS, a true old school classic
The only flaw is how easy it was to finish the game by not rising in the ranks. You can just go kill the bosses off the bat and the game could be won in a couple of hours. But what fun is that? The audio and sound effects are top notch considering when this game came out. And the graphics have their own style, and really help you get sucked in to the reality of being inside a video game, ah la tron'esk. But the most important factor about this game is that I re-played this only a few weeks ago and still had a blast and I can't say that about 90% of my games that are 10 years + old. I think that says a lot about the idea and creativity of this game.
