A collections of 'trick' sections to help you tune your pmove_fixed 1 skills. My personal favourite is the Race section. It is possibly the longest corridor in game history. The floor (grass) on the Souls Speed Room track (right side of the teleporter) is slippery so you slide and keep sliding, the other track is standard. Use cheats to give your self weapons and health, then run, rocket slide or plasma slide until you are sliding faster than rockets and plasma balls. There is not much else to the map.
Only really for people that want to practice pmove_fixed tricks.
