Back in 2008 (I think) the website 3DBuzz held a mapping contest. My submission to that contest was a map I called Sunken Pagoda. I never got it out of alpha due to hardware troubles. By the time I had a PC that could handle UT3 again most of my friends had moved on to other games. I have picked it back up a couple times but have never finished it. I hope to change that soon.
The map consisted of an Asian estate, the house on which had collapsed into a sinkhole. It has allot of z-axis game-play, winding passageways, soaring launchpads, secrets. It has also trigger-able booby-traps as well as magic healing fountains... I like to pack allot of interactivity into any map I make.
This is a shot out across the sinkhole.
