Need for Speed: Shift: Throttle Edition

Need for Speed: Shift: Throttle Edition is a driving-game from Slightly Mad Studios, with tweaks offered by 984 Studios. The game is exactly like Need for Speed: Shift, but includes more powerful variants of cars, deletes some cars, adds several new cars, and also adds a few new tracks.

The Newbies And Dead Guys
