Red Eclipse, An Open Source FPS
Ooh, I do like a bit of fast-paced FPS, like they don't make anymore. And here's v1.0 of Red Eclipse, which is an open-source project along those lines. I've not had a chance to take a look at it yet, but the trailer (below) shows the kind of action that I tend to get a kick out of - dudes bouncing about and running along walls, and all that jazz. The game is based on the Cube Engine, which has some games of its own going at that link.
All of which reminds me - sorry guys - that I really want to get back into Quake III...
