The Remedy Entertainment mobile racer Death Rally has hit Steam today, complete with a graphical overhaul and other improvements. It's available now for $9.99, but you can grab it for $8.49 through August 10.
In addition to the HD visuals, the camera and controls have been optimized for PC, with support for both controllers and keyboard. The career mode has also gotten a bit of an overhaul, by unifying single- and multiplayer progress into one. Finally, the game includes a new track called Savo, the return of the Shadow Man, new weapon combinations, 6-person multiplayer, and Steam achievements.
The game and (light) system requirements are available on Steam.
