Here's something thats been laying around for a while so I decided to pack it up and release it as an alpha, it's not polished or especially finished but worth a look.
The map was designed and built by CMM members, tested extensively as a CTF layout with the guys from sC'ore and also supports bomb, TS and TDM.
Here, have some screenshots, I've been gardening and my hands smell like blood, fish and bone...





The map is quite dark with gamma 1, too dark probably.
You can download the pk3 here
You can also try the map out on the 4.2 CMM server
