Coop lag

Every time I play any campaign on coop online I or my friend experience a great amount of lag it makes the game really on playable and needs to be fixed because the connection issues are horrible on the collection of halo

Have the same problem, played four hours of co op the other day spent about 2 and half of it hiding in corners waiting for lag to clear then it booted us at the end of the level. Would say i’m never going to play the game again if it doesn’t get fixed, but they got my money already so what do they care.
