Hello TinT Here how are you all? 
just wondering, is the halo campaign ever going to be cross play? and maybe, i doubt it but will halo 5 ever come to PC/MCC, (even if i have to pay for it i think it would nice to be able to enjoy the whole game storyline, in 1 place, as it is called "(HALO) the master chief (collection) - and even if halo 5 isnt as focused on chief, he still in the game,
thoughts?
thanks tint : )
Well no one can really answer if they will EVER happen, but from things I have read neither are in the works. I want to say that I read somewhere due to how bungie coded their halos it would take 343 6 months per game to give crossplay campaign. I could be misremembering, but everything I have seen says their main focus is the launch and updating of infinite and they have a side team that works on mcc, but after season 10 we may even lose that team to infinite. That halo support landscape is very up in the air right now, I think after infinite has co-op and forge added in and mcc season 10 have dropped we should start learning alot more about the future of halo support. Sadly that means probably another year or so before we know more long term things. Just my thoughts and interpretations though, could be wrong.
