For Xbox Series X / S owners, two new dynamic themes have been added based on Halo Infinite and Wasteland 3. Both are available for free right now. The Halo Infinite: Courage theme depicts the Master Chief in the midst of battle, while the Wasteland 3: Cult of the Holy Detonation theme is based on the main DLC for the game.
Themes can be previewed in the Personalization menu on consoles.
Let me remind you that the storyline campaign Halo Infinite comes out December 8th on PC, Xbox Series and Xbox One, and the multiplayer beta is now available for free. You can pre-order the game now.
