Today an old game with some new tricks hit Android. It's Duke Nukem, the 15-year-old classic console game. The object of the 1991 shooter is still to save the women from the invading aliens — "save our chicks" — but there are some new features to take advantage of 2011-era mobile tech. Those include the ability to install from an SD card, multi-touch controls and compatibility with an array of Android screen sizes, from phone to tablet and beyond. The game's current owner, Machineworks Northwest, did a version for iOS this summer.
