Pilotable vehicles are a new addition to the franchise and there's no lack of variety. Duke can commandeer any car he sees on the Las Vegas Strip(GTA anyone!?), but there is plenty of futuristic fun to be had behind the wheel of any one of eleven original sci-fi vehicles including the Viper Ship, the Pig Tank, a rocket-fueled mule, and a hovercraft.
Duke Nukem Forever is being built on a proprietary graphics engine called DukeD. This allows more shaders or lights or something. We don't know, but the result is certainly a feast for the eyes!
All we can say is: Shake it, babies!
