That's a fun map :) created to be played in Quake 3 Arena. There aren't copyrights on it but if you want decompile it to create a "pro" version i prefere you'll ask me before :S
The idea on this map is a map like the Q3DM16 but much largeer and much bouncy ^_^

This version is an update to the original release and includes a missing texture. - lvlworld.com/ - 06 May 2006
