Well 0xA5EA and his team have finally released a beta for the much anticipated KingpinQ3:-

after dealing with KingpinQ3 for about eight years we are proud to announce a Beta release of KingpinQ3. You can download the game from here -http://www.kingpinq3.com/index.php?option=com_content&task=view&id=109&Itemid=39
The beta includes three ctf and bagman maps and four deathmatch maps. We have a couple of server running for Capture the flag, Bagman, Team Deathmatch, Hitmen, Realmode and Gangbang.
The beta also includes everything you need to create custom maps on windows (radiant, compilefrontend, tons of textures and map-models).
Supported operation systems are currently windows, linux 32-bit and linux 64-bit.
I've created a forum for feedback and bug reports here - http://forum.kingpinq3.com/
So have fun.
We have all been waiting a long time for this so now you can go and download it and check it out on the KPQ3 servers
