The PC demo for DiRT Showdown is now available on Steam. The taster includes one single-player race, 8-ball, which takes players through San Francisco and across the Golden Gate bridge. If you challenge a friend, you’ll also be able try out the eight-player Rampage mode. The demo supports RaceNet, Codemasters’ answer to Autolog, and signing up nets you $20,000 of in-game currency when the game launches. You can also grab the demo from the PlayStation Network or Xbox Live Arcade. DiRT Showdown launches on May 25.
