Whenever my friend and I play halo 2 co-op campaign together at a random point in the game we get split off into different co-op sessions yet stay in the same. On his screen I am there but either walking into a wall shooting randomly and doing nothing while in my screen I am doing the mission while his character does the same. We play on legendary so when I die it resets the checkpoint but not for him and vise versa.
Can I get some help here from a fellow MC fan to his community.
