Microsoft put out a direct-feed version of the Campaign mode gameplay demo given for Halo: Combat Evolved Anniversary at E3 during the San Diego Comic-Con, this past weekend.
The clip is commentated by 343 Industries executive producer Dan Ayoub, who says that the primary goal of Annivesray is to allow the fans to relive the game they played a decade ago. To exhibit that, he shows off an exciting feature, which allows you to switch the visuals between what Halo looked like ten years ago and what it looks like in this new remastered release.
