Halo: Reach releases later today. The other games are Halo: Combat Evolved Anniversary, Halo 2: Anniversary, Halo 3, Halo 3: ODST and Halo 4.
Microsoft will be rolling out the rest of MCC on PC throughout 2020, starting with Halo CE and moving chronologically after that.
Reach is also available via Xbox Game Pass on PC, and while we don't have player counts for that platform, Microsoft's heavy promotion of the service likely means there are quite a few players there. And the good news is that if you have Xbox Game Pass Ultimate, you can also download Reach on PC.
Microsoft announced the full release today, confirming all the different ways you can play it in the process.
Steam usually tends to peak between midnight and 3:00 AM AEDT Australian time, and as more people get the game tonight (internationally) and download what they need, we should get a better sense of how big Halo's PC launch actually is.
Halo: Reach tells the story of the Noble Team, a group of Spartan supersoldiers desperately trying to protect the Earth-like colony Reach from a Covenant alien attack. Five other Halo games will follow, ending with Halo 4 by the end of 2020. The Halo Sticker Capsule was also added to CS:GO, making the tactical FPS all the more sci-fi.
KitGuru Says: It has been years since I last played the Reach campaign, so I'm looking forward to finally getting this on PC later this evening.
Unfortunately for those picking the game up on Steam, there is no pre-loading available, although if you use the Steam mobile app, you can activate a remote install on your PC while you are out and about.
In the latest MCC Development update, 343 Industries mentioned that the PC version is launching today with an experimental implementation of variable frame rate (VFR), and some features such as File Share, Forge, and Theater will be available at a later date.
