If you bought the digital version, as I did, it should download the deluxe dlc automatically. If it didn't you can go to "manage game" for Far Cry 5 in games and apps on Xbox One and under "ready to install" the dlc should be there. To access the dlc items in game you need to clear the first area, Dutch's island, and then go to any general shop to equip the dlc items. I hope this helps if you have a digital version. If not, then you should have a code in the disc case somewhere as mentioned above.
If you go to manage game, any dlc should be either already showing as installed or in the ready to install section. If not, are you sure you bought the deluxe version? If so, then you need to contact Microsoft for help with your purchase. Ubisoft can't fix it.Originally Posted by BluesLizzard Go to original post
420JJ is correct, if you bought it digitally and it's not waiting to be installed, you will have to reach out to Microsoft.
