Halo: Reach

Description
Halo: Reach is a remastered HD version of the Halo: Reach campaign and multiplayer originally released back in 2010. Players control Noble Six, a member of a Spartan Team during the fall of the human colony Reach.
It is the first portion of the 2019 compilation release Halo: The Master Chief Collection for Windows and Windows Apps. For Xbox One the 2014 compilation release Halo: The Master Chief Collection was re-released at the same time and included it by default. Owners of the 2014 Xbox One compilation release received the main multiplayer portion for free and had to buy the rest (the full campaign and Firefight co-op mode) as the DLC Halo: The Master Chief Collection - Halo: Reach.
This game is advertised as DLC for Halo: The Master Chief Collection, but is available standalone as it comes with a free launcher.
