Duke Nukem 2 has been released today on the iOS App Store for iPhone, iPod and iPad.
The game's re-release marks its 20th anniversary since its original outing in 1993. Duke Nukem 2 is an action side-scrolling shooter, where Duke made his name before starring in Duke Nukem 3D and becoming known for first-person shooters.
3D Realms teamed up with Interceptor Entertainment to bring the enhanced version of Duke Nukem 2 to Apple's iOS 6 devices.
The new iPhone/iPad version promises 32 levels of smooth 2D shooting, touch-screen controls, new artwork and options to save, load, replay and track your score via leaderboards.
