Halo: MCC Steam, can't install Halo 4

it is because its part of the halo MCC, you need the base part which is halo MCC then the individual games so it reserves space for them, halo 1 on pc for instance is 8.58GB and then add on the MCC base game it becomes 30.08GB.

halo mcc consists of all the games which take 142GB of space on pc so it saves this space aside, when you install hmcc and just one of the games which is also split into multiplayer and campaign it looks like it still reserves the space, this is what i have seen on xbox and gamepass pc, when i install via steam and just choose one of the games to be installed then the space taken is just by mcc and that one game.

I can't play any of the 4 campaigns in Halo MCC.

Since it is an Xbox Exclusive I doubt it will come to steam, that being said, Halo MCC is on steam if im not mistaken

There are a lot of good games on the game pass. I mean, I can't decide for just one.

But those who I love are Doom, Fallout 4, Halo 5, Halo Wars 2, Halo the MCC.

it works the same as halo mcc, i own that game on xbox, windows and steam, when i start the steam version you have to use your xbox login to sign in as it uses the xbox network services.

foza 4 does the same.
