This level came from the idea to cross narrow beams over endless space in an attempt to give players vertigo (an uneasiness caused by hight). It then became the level it is now, a bizarre style of space station made of separate buildings connected only by concrete beams. There are several buildings that are all different and provide different areas of combat. The newer version was made because there were errors that needed to be fixed so I added new things to it such as the barnacle targets to allow you to traverse the level quicker. I also made a secondary science lab so that you press a button that can toggle the teleporter to take you to either the Primary Science Lab or the Secondary Science Lab. There are also other spacey items such as the jump pads and spaceship. This level is also very interactive with many things that you can use to cause havoc in the game. Certainly one of my most unique levels I have made.
Looks interesting from the screenie.
It's quite popular, i've played it on several servers.
