Fallout 4

During Microsoft's E3 2015 press event, Bethesda Softworks revealed two Xbox One exclusives for its upcoming post-apocalypse RPG Fallout 4. One of them is that every copy of the Xbox One version will include a copy of the previous game in the series, Fallout 3.

The other exclusive is that any mods that are created for the PC version of Fallout 4 will be able to used on the Xbox One version as well. Details on how this will be accomplished have yet to be revealed.
