Earlier this week, 343 Industries confirmed that split-screen local co-op in Halo Infinite has been cancelled outright – so players are now doing it themselves.
“After checking on Series X, the menu glitches to play Halo Infinite campaign splitscreen still work: no crash in cutscenes, no issue with AIs, etc.,” confirms Halo Creation, who says the workaround supports four players and doesn’t seem to break cutscenes.
