Sorry nap, but Overlord is the easiest map for me to set up due to its simple corridors xD. I imported the geography and some basic lights, but had to re-create a lot (including texture the whole thing), so Overlord was the obvious choice. You're right, the map kinda sucks (especially right now as only self-hammer is working). I have a pro-mapper working on a complete recreation of Ballistic, just designed for the UT4 quality. That should be extremely exciting.
I look drunk probably because I am drunk.
