It could have happened: Halo on DS
Matt Cassamassina over at IGN has updated his blog with a supremely interesting entry: apparently, a version of Halo was quite deep in development for the Nintendo DS. Though several publishing mishaps resulted in the eventual cancellation of the project, one must wonder what could have been.
Indeed, Matt C. even got to play an early build of the project, impressed with the accurate recreation of perhaps the world's most popular console shooter. He compares the gameplay to that of Metroid Prime: Hunters, but, you know, Halo-fied. Certainly, when you walk past the pearly gates and into Gamestop's heaven branch, this game will be at the forefront. You know, right next to Chrono Break and NiGHTs 2.
