RvBChandler has set up a group for people who have made, or are making, maps for the Unreal Tournament 3 mod UT2D.
To get the ball rolling I've had my map UT2D-Ducts associated with the group (thanks to ModDB staff for changing that for me), hopefully more of the ever increasing number of people mapping for UT2D will follow suit.
If you're not familiar with UT2D, it is a mod by jbizzler that turns Unreal Tournament 3 into a side scrolling shooter. It's very entertaining, generally total chaos and you can check it out via it's ModDB page right here.
Also, if you know how to map with Unreal Editor then why not make a map for UT2D? It's pretty simple and begging for more maps whether they're original or based on environments from other 2D games (there are a couple of maps based on Super Mario Bros. for example).
