My copy of Halo 4 won’t work anymore. 
I got the LE on launch day and this was the first time i’ve tried to play in a little while (I was going to get the Monitor emblem) and when I put my game in the tray, it only says ‘Open Tray’.
As an avid player of all Halo games, this greatly disappointed me.
Has anyone else had this issue, or is it just me?
well sorry, it just sounds like a disk issue, not much you can do if it really refuses to work other than buy a new copy, sorry you missed the emblem because of this
