This game only on the 360 I join a match (if I can cause match making times are slow) it’s laggy or I get kicked or when I finish the match I’m disconnected from xbl or I get the default playlist thing. I have my NAT open my ports forwarded and this still happens. Anyone else having the same problems?
- clear system cache on hard drive, Google Xbox 360 clear cache if needed- ensure disc 1 is installed in addition to disc 2 you originally installed… (1) Dashboard 》home (2) instead of A to start game, hit X Game Details (3) Should see install option, select your HD when prompted… ~20 minutes- start game up, sign in if needed, power off console- do 1 againhope this helps
I am still getting disconnected 
Have you checked your NAT?

Is your copy of Halo 4 a physical copy and if so, does it have noticable scratches on it? Damage to the Halo 4 disc seems to have weird effects like certain Campaign missions won’t ever load, certain maps won’t load, etc. It’s worth looking at as that might be your problem.
is it a disk or downloaded?
