I try playing the co op campaign and it wont work. it says error and then i have to shut my xbox and then go back on halo 4. The worst part is that the only thing i can do is play spartan ops and maybe sometimes matchmaking will work. Also my War games pass code didn’t work i put in the code used it to buy the map pass but now it doesn’t say that i had purchased it to buy my war games map pass and it doesn’t let me download any of the new levels.
