I've been working on two mods, one longer than the other, here's some of my work so far, none of these are from finished maps.
From a forest:
From my recreation of Hyperblast 2 from Unreal Tournament 2004
From an underground chamber, for relaying power, blah, blah, blah, typical puzzle scenario
From the central room of an underground complex, which is surprisingly small, or at least the part you get to see is.
Completed work due at the end of summer.
