Yesterday I purchased Halo: MCC on Steam and got the Halo: Reach DLC. When installing the game it only installed Halo Reach. Whenever I open MCC I’m limited to just Reach Multiplayer And Campaign, even though I have bought all of the other games. In steam it says they are “Not Installed” When I uninstalled and reinstalled MCC i had the same problem. Does anybody know how I can fix this?
Unfortunately Halo: Reach on the MCC is the only game out for PC/Steam currently. All the other Halo’s are coming in Chronological Order in 2020. So you just have to wait for the time being.
I hope this helped!
