A question that I’ve seen asked a few times is whether you have to buy the full Halo Master Chief Collection to play just one game. As you’re probably aware, Halo Reach was finally just released on the PC platform. The other Halo games will be released throughout 2020.
All in all, the collection will include 6 Halo games: Halo Reach, Halo Combat Evolved, Halo 2, Halo 3, Halo 3: ODST and Halo 4. The answer as to whether you have to buy the collection is no, you don’t.

The total cost for the Halo Master Chief Collection bundle on Steam in the UK is £29.99. Where as Halo Reach is for sale at just £6.99. If you think Halo Reach is the only game you’ll play (or want), it’s a much better idea to get the cheaper option.
It’s a little misleading, as on the Steam page, it’s marked as a DLC. Next to the “DLC” option, it says ‘This content requires the base game Halo: The Master Chief Collection on Steam in order to play’ when it in-fact doesn’t. It only needs the launcher, which is included anyway with your download.
I paid for just Halo Reach, and everything is working the same as if I’d bought the entire bundle. There’s full access to multiplayer, the campaign, firefight and everything else. But when the other Halo games do eventually release, I’ll have to buy those too to be able to access them.
If we assume that all games will cost £6.99 each, you’re saving around £12 by buying the bundle. But if you only want certain games, it’ll work out cheaper to get them individually as long as you don’t go for more than 4 games.
However, buying games individually will not decrease the price of the Master Chief Collection, it will always remain at £29.99. For more Halo MCC Guides and content, make sure to check out our dedicated area here!
