Duke Nukem 3D has officially hit the iPhone / iPod Touch, and it’s priced at just $2.99 through the iTunes App Store. Players can choose from either traditional thumb stick or slider-style controls. Video after the break.

This high-powered iPhone 3D engine supports TapShoot, a unique way to play first-person shooters taking full advantage of the touchscreen interface to quickly shoot enemies, without trying to line up your weapon perfectly.
