Reach was followed by Halo: Combat Evolved Anniversary in March, Halo 2 Anniversary in May, and Halo 3 in July.
343 Industries began the task of bringing The Master Chief Collection over to PC in December, when it launched Halo: Reach on Steam and the Microsoft Store. So, even though Halo 3: ODST has been part of The Master Chief Collection on console since 2015, it seems that even Xbox One owners are getting something with next week’s launch. Apparently, ODST Firefight will be coming to the console and PC versions of The Master Chief Collection with its own matchmaking and dedicated servers. Halo 3: ODST also introduced a new multiplayer mode called Firefight, which Microsoft touched on briefly in a separate announcement today.
Set during the events of Halo 2, ODST puts players in the role of an Orbital Drop Shock Trooper from the United Nations Space Command and tasks them with exploring the city of New Mombasa.
Halo 3: ODST was originally released in 2009 as a spin-off to Halo 3. Suit up, strap in, and prepare to return to New Mombassa. Halo 3: ODST will officially arrive on PC as a part of the Master Chief Collection, on September 22nd.
