As promised, our favorite cigar smoking, wise cracking first-person protagonist has hit the Android Market, and it didn't even take 15 years. The mobile version of the classic FPS is available now for Android 1.6 and up (that's according to the Market listing -- its producers recommend 2.1 and up), courtesy of Tapjoy and Machineworks Northwest as a $0.99 download. And don't worry, there's plenty of Duke to go around.D
