I'm surprised this scored as low as it did. For the time, this is a really forward thinking shooter especially when compared to the dumpster fires that were usually uploaded to the portal at the time. The 3D engine provides depth, literally, as it tasks you to move your player backward and forward mainly for ammo pickup. With 3 weapons, that's 2 more than you usually get in these shooter games.
It can be a little jarring to play, but overall I'm very impressed with this one.
