Currently, it is filled with exploits that people use to make the game unfun and unfair for zombies. These exploits include being able to use trimping, which is exploitation of the source engine's physics, to get to otherwise unreachable spots. These spots are all unreachable in the CS:GO, which this map was originally from. The Mannpower powerups are extremely unbalanced, and can cause game-breaking and unfair rounds for zombies. Things like the plague powerup, when put in the hands of someone capable, can easily turn any round COMPLETELY around in favor of the humans when, that round, in under any other circumstance, would be unwinnable. You are able to literally beat the entire map by yourself as a demoknight with a strong enough powerup. I have done this myself several times. Some of the instructions given on how to complete certain objectives are extremely vague, leading to people not doing what they are supposed to because they have no idea how to play the map, and making progression through the map slow to a crawl. There are spots in certain stages where you can stay without being teleported ahead with the zombies to force progression. And so, if everyone on the humans team dies except for the one person who chose to stay behind, the server has to voteslay in order to kill that person without an admin being present. I believe that if most of these problems/glitches above are fixed, the map will not be nearly as popular due to the fact that this map is the only one on the server where issues like these are magnified to such levels, and that many people enjoy this map solely because they can exploit these issues. This map is only popular mainly due to the following reasons: it is long, unique(much more different than any other map on the server), has "funny memes" in it, provides some sort of a challenge, moreso than other maps, and it allows you to do things that you can't do to such an extreme on any other map. For being the "best map" on the server, it has a ridiculous amount of problems with it and far more so than any other map.
