Duke Nukem 3D is definitely of the old-school FPS mold, so Halo fans will likely wonder what all the fuss is about. But gamers that grew up with corridor shooters and the fine art of clearing room after room of aliens and monsters will enjoy the pacing of Duke Nukem 3D. The control schemes offered here are not for everybody -- they take some getting used to and even then, all of the buttons can be somewhat overwhelming. (I know that some players will never like the control bars set-up MachineWorks has devised here, but right now, they work better than any other iPhone FPS.) However, this is an extremely well-produced port of the classic Duke shooter for PC that fans of the series should celebrate and definitely use to fill the time between now and the eventual release of Duke Nukem Forever... whenever that is.
