Players who purchased Halo: The Master Chief Collection and played before December 19th should have something nice waiting in their Xbox Live messages: a code to download the full Halo 3: ODST campaign on Xbox One.
The download, which clocks in at 8.1gb, will allow players to play all of Halo 3: ODST’s single-player and co-op campaign. Halo 3: ODST has been fully ported in 60 FPS just like Halo 3. Unfortunately, firefight is not included in this download.
Oddly, the game isn’t showing for sale on the Xbox One store yet. The game will cost $4.99 to those who hadn’t played MCC before December 19th, and will require Halo: The Master Chief Collection.
