Im getting the physical LE on launch so I dont yet have a Halo 5 file on my one. I entered a code from a Monster pack and it was accepted but I cant find it anywhere on my console. I know i wouldnt be able to open it yet but i should still see it somewhere, right?
Dont worry about that, its normal. its not a regular DL so the XBO wont see it as Halo 5 dlc but it should be there when you play it.
You will see the REQ in the REQ collection on the 27th
