Me and a couple other players played on block for the entire time rotation, it did not have any sound bugs or bugs of any kind, the only thing I didn't like about was that the minigame at the end is time consuming, but that can be fixed.
Also this is the current version of darkenergy, you cant get stuck on the fans and teleporters, I tried doing that when I went through it, the only exploit I discovered was a fault in the two traps, as mentioned above.
