The game in question is Carmageddon: Reincarnation, which has been a very popular Kickstarter project. Funding ends today and with a "stretch goal" of $600,000 USD they were going to provide a Linux and Mac OS X client. They're only at $578k right now, but the developers have said regardless they will be providing a native Linux version of this unique racing game (via this update).
Here's some information describing the game from their Kickstarter game: "Carmageddon: Reincarnation is going to reintroduce the gaming world to the original freeform driving sensation, where pedestrians (and cows) equal points and your opponents are a bunch of crazies in a twisted mix of automotive killing machines. It’s the racing game where racing is for wimps. Originally released for the PC in 1997, Carmageddon was an instant hit thanks to its anarchic gameplay and over-the-top surreal comedy violence...Carmageddon: Reincarnation is a re-boot of everything that made the original games such a blast to play. The new game will be inspired by the classic environments, cars, drivers and power-ups from the original, but dragged screaming and kicking into the current state of the rendered art. And of course, there will be a bunch of brand new STUFF too, including true rag-doll pedestrians and physics-based power-ups that let you mess with their limbs whilst wiping away the tears - of laughter!"
Many Linux gamers can now rejoice that were excited about this title to begin with while other gamers can be happy that it's just not yet-another-first-person-shooter working its way to your favorite Linux distribution.
