successful racer, Death Rally, now is probably the time to do it. The car-combat title is currently free on the Apple App Store. It's only free for "a limited time" however, so get it while the gettin's good.
Remedy is also giving away an iPad via the Death Rally Facebook page. To enter the giveaway, users have to simply "like" Death Rally on Facebook. You should probably actually try the game first, of course. Not that we're suggesting anyone would ever "like" something dishonestly.
