You know what it looks like when you have a mirror on one wall, and another mirror right across from it on the opposite wall? You see a mirror inside a mirror, inside a mirror, etc. The author created this same effect with warp zones. It looks like you have several miles of battlefield ahead of you, but instead, you're just warping from one side of the room to another. It's a cool trick that could help you get out of trouble. Another cool thing is the glowing blue goo, or water, or whatever it is. It appears as though you are running amuck in minty-fresh, bio-toxic Listerine. Stranger things have happened. Gib-worthy weaponry is pretty much all you get, which works for me. I like to watch the chunks fly into the blue liquid. Ramps and lifts get you from one floor to the other, the z-axis is there, but limited, it's fast, and it is designed to be played with 2 players.
