Halo 3, Halo 3: ODST Campaign Edition, Halo 4, Halo: Combat Evolved Anniversary added to Xbox One backward compatibility

Four Xbox 360 games are now playable on Xbox One, and they're all Halo titles.

Microsoft announced today new titles featuring backward compatibility with Xbox One were now available.

The new titles are Games on Demand versions of Halo 3, Halo 3: ODST Campaign Edition, and Halo 4.

Halo: Combat Evolved Anniversary was also added today as a disc-only option.

This latest round of Halo games join previously released backward compatible titles Halo Wars, Halo: Reach, and Halo: Spartan Assault.

Halo 3 and Halo 3: ODST Campaign Edition were the last games in the series to be developed by Bungie, before 343 Industries took over the franchise in 2012 with Halo 4.

It's worth noting the the Games on Demand version of the Halo 3: ODST Campaign Edition includes only the campaign and Firefight modes. In other words, it doesn't include Halo 3's competitive multiplayer or maps.

Halo: Combat Evolved Anniversary is the 2011 enhanced remake of Halo: Combat Evolved, and was re-released by 343 Industries as part of Halo: The Master Chief Collection on Xbox One in 2014.

With today's additions, there are no w 425 playable Xbox 360 games on Xbox One.
