Coop campaign unplayable lag

Half a second delay between imput and result is unaceptable. Why is it i can play GOW coop over live with 4 players, but cant play 2 player coop without lag on any of the halos on the MCC???

Because 343 doesn’t know how to make a game online sadly

I actually remember having this problem in halo ce anniversary too and I don’t think it ever got fixed.

Play solo. It is easier than co-op on legendary.

Need dedicated servers for co-op campaign.

Will never happen. Just have to deal with it.
