Halo 5: Guardians, Forza Motorsport 6, Gears of war: Ultimate Edition, and Rise of the Tomb Raider have each sold over one Million copies.
The sales milestone was announced on Xbox Wire in a post about other records Xbox broke this holiday season. While Halo 5’s launch was the biggest in franchise history, Tomb Raiser’s milestone is impressive considering that the Xbox exclusive still has to hit PlayStation 4 and PC. The PS4 version is said to release sometime during the 2016 holiday season, while the Pc version is coming later this month on January 26.
Rise of the Tomb Raider’s DLC Baba Yaga: The Temple of the Witch is also arriving in January. This DLC includes a new outfit, a new bow, and will expand on the main campaign’s story.
