For all of you who already knew, the new Halo 4 trailer came out today, and multiplayer will have players being Spartan IVs. However, 343 also announced that there will be somewhat of a storyline as to WHY the red spartan IVs are fighting the blue Spartan IVs (Blue looks more purplish to me however).
any ideas what that story is? my best guess has something to do with a UNSC rebellian, forcing some spartans to fight for the UNSC, and some to fight for a new government. Maybe campaign would feature that too, mixed in with Covonent or Forerunners or whatever the hell the enemy will be.
