This short level is some apartment building with no apartments or anything else you should be able to find from a building. But there is some toxic waste, underwater caves, empty rooms, flashing hallways etc. Design is empty and there are neither much shadows nor light sources. Puzzles are simple although the first time I went through the level I experienced some major problems due to lack of ammunitions (I accidentially choosed s2 instead of s1). The battle against one Battlelord is 'ok' as well as the hallway with some cyclers.
