Ok, we seem to have settled on a release date - Ricky's map was at 73% vis and counting at last check, I've got a few different meshes and sounds to fix and we're good.
So in order to have a stress free life 'this weekend' is the new date, you lucky people.
So get ready to tear yourselves away from the Steam purchases and enjoy 4 (!) new RMQ levels. This release will also include a full devkit, with the tools for BSP2 and the various sources for everything as well.
