dm_digsite was one of my first forays into using the Unreal 3 Engine, and I made this level in six weeks for an assignment in my first year at University. I still think this level could do with some polish, even though it received a high mark. Maybe one day I'll revisit it and create a better digsite.
Word of warning: Due to the age of Unreal Tournament 3, getting this to play properly may prove to be a hassle. I recommend using an older computer with an older graphics card and drivers, since UT3 seems to be incompatible with mine.
