ive had this problem since last night. Im on the mission reunion and it keeps freezing. Ive tried reinstalling the game and it still does it? Any help? Anyone?
Nope, played the first three missions smoothly, except for the stupid spartan AI.
Ughh -Yoink!-! Only reason i bought the game was for Campaign! Fml 
mine is freezing at “meridian”. Beyond irritated at this point.
