In a blog post on the Xbox website,
Halo 3, Halo 3: ODST, Halo 4, and Halo: CE Anniversary will all come to Xbox One backward compatibility later this year.Each game will support campaign, multiplayer, and LAN play. In a very welcome move, LAN play will also support connecting both Xbox One, and Xbox 360 consoles.
In an even more welcome move, every Xbox 360 map pack currently on sale in the Xbox Store will be made available to download for free. Please take note, Activision.
As with other Xbox One backward compatible titles, the original Xbox 360 game discs will work just fine. However, if you don’t own the physical versions of the games in question, you will be able to download them direct from the Xbox One Games Store.
343 Industries have also announced that Halo 5 will receive a 4K upgrade on the upcoming Xbox One X console, and that a new expansion for Halo Wars 2 – titled Awakening the Nightmare – is in full development. It’s due to arrive on Xbox One and PC this fall.
The team at 343 will be attending a number of community events in the coming months. Events are scheduled to take place at RTX Austin 2017, the HCS Summer Finals at DreamHack Atlanta, ChinaJoy, and Gamescom.
