The basic premise of this net level is that it's set in a winter climate where snow and ice cover the ground, the result of which is that your traction with the ground is greatly reduced. It takes a while to learn the new techniques necessary (don't hold down the run key for a long time and use weapon recoil for maneuvering), but it can be fun once you get the hang of things. The map itself is fairly big (> 4 players would be best) and set up for multiplayer carnage with open large chambers on multiple levels, linked by elevators and narrow staircases.
