Finally updated this piece of junk, lol. I've completely overhauled the main area, and done quite a bit of optimizing. This turned out to be more of an experiment in making a completely indoors environment in TF2, but I hope it's still enjoyable. Considering expanding the playing area, or simply converting the map into arena.
