Yesterday, Escher Physics went live. This system allows UT2004 mappers to create stuff where they can have gravity of all directions, irrespective of the limitations of the UT2004 engine. There is also a map some friends and I created to show off its potential.
Marshmallow Duel : Mowbray's Revenge is also nearing the end of its first development phase, and it should be released within 3 weeks. All the core stuff is completely final, we are simply adding more map and character content before it comes out.
Oh yeah, the site has undergone quite a few updates and should run much nicer for everyone, particularly when loading page subsections (this is now parsed serverside instead of sending the entire page to you and cutting out the irrelevant stuff).
