This not only brings confusion, it brings boredom killing each of them to get them out of your way. Its funny how they did an incredible plane model, a tank model, and a 'black hole generator', ala Quake2, yet they skipped on the actual interactive characters. The good models in this TC are the ones that are stationary, or not very interactive at all. You run down a corridor, which brings you to another corridor, where you push the same button you did before. Then you jump on the lift, looking for the same button, to open the door that you passed at the beginning of the level.
Sky is everywhere, and there is a certain gravitational pull of it.
So when your incredibly high up in the air, not only do you have no idea where your headed thanks to the horrible lighting, the slightest mistake will bring you over the edge to death. The levels are a 'Future Base', and a 'Present Base'. Funny, I couldn't tell the difference between either. This TC takes the Quake color pallette, and ruptures it, throwing wild colors in the most insane situations. The shadows are not black, they are green.
