Halo Infinite's campaign co-op feature isn't set to arrive until May 2022 at the very earliest, but a few players have already found a way to glitch into it. A warning though, it definitely comes with some caveats.
We're not going to share the instructions because we don't advise attempting this practice (it's obviously not meant to be a feature right now, and it could lock up the game / crash your console) but here's a look at it in action:
Those who have tried accessing the co-op have pointed out that the game will soft lock if either player dies, and the second player in particular suffers with a variety of problems such as the HUD not appearing at times. Basically, it just seems like a very work-in-progress build made its way into the game, and it's certainly not very reliable.
Others have also stated that they've tried to access the co-op in the same way, but it simply doesn't work for them. Your best bet? Try and remain patient, and we'll all hopefully be able to get official access in a few months' time.
