MachineWorks Northwest has brought the first-person shooter Duke Nukem 3D to the iPhone and iPod touch. The game follows the same story as the original 3D Realms release from the late '90s. Players take the role of Duke as he battles an alien invasion in Los Angeles. The game features a variety of mutants and aliens, along with a wide range of available weapons.

TouchShoot technology provides a quick way to aim at enemies and fire weapons. Users can guide Duke using either a virtual thumb-stick controller or slider-style input.

Duke Nukem 3D carries a 12+ rating and can be purchased from the App Store for $3.
