Brink (video game)
Brink is a FPS using a heavily modified id tech 4 engine. From the screen shots and videos alone, the modified id tech 4 engine looks a lot like the id tech 5 engine used in RAGE.
Brink will be available on Steam with VAC and achievements, and so on.
There's some videos of gameplay footage on youtube. I have to say...I'm impressed. Splash Damage really outdid themselves, especially with overhauling the id tech 4 engine into id tech 5 territory.
