Halo 3: ODST is finally arriving on PC on September 22 as part of Halo: The Master Chief Collection. Both the campaign and Firefight--the wave-based survival mode--are heading to PC for the very first time following a recent beta period.

The Halo 3 spin-off is the penultimate game coming to The Master Chief Collection on PC, with Halo 4 wrapping up the compilation at some point in the future. ODST's campaign has been available on Xbox One since 2015, but Firefight is only scheduled to arrive on the platform this year. Developer 343 has yet to announce a release date but it might only be a matter of time now that it's pencilled in for a PC release.

Update: Microsoft just announced the next wave of games coming to Xbox Game Pass on console, Android, and PC, including ODST. The game's description says, "Firefight is joining The Master Chief Collection on console and PC for the first time, with online matchmaking, dedicated servers, and new custom game modes." This would imply that Firefight is also coming to Xbox One on September 22, but it's not an explicit confirmation.
