Microsoft’s 343 Industries has released a new trailer for Halo: Combat Evolved Anniversary that’s part retrospect, part behind the scenes of the upcoming game’s campaign mode. In the trailer, team members of 343 share their own personal experiences of the Halo series while detailing how key aspects the series have been carefully and intensively crafted into the new remake. The team at 343 made it their goal to update the graphics, textural designs, and even Master Chief’s armor, and add new elements like online Co-op, Kinnect and 3D functionality, and skull modifiers – all while staying true to the Halo storyline and style of gameplay.
