As I’ve mentioned in a previous post, it’d be sweet to see a new squad of ODST’s fighting at the end of the Human-Covenant war, using the old art style and everything, and their transition into the Spartan-IV program, to battling Insurgents and eventually the now defunct Covenant.
I wouldn’t mind a 2nd game similiar to Halo 3: ODST. It was a good side game and a change in perspective. But I think they should leave out the Spartan-IV Program to focus on regular humans like how Halo 3:ODST did. Then again maybe for a Legendary ending, they could show them being offered to join the Spartan-IV Program. Would also be cool if the game had it’s own unique multiplayer but I doubt that would happen, then again we don’t know what 343 has planned.
