World at War Comes to Backwards Compatibility on Xbox One
Early next month, the final chapter of the Nazi zombies story line will potentially be over when Black Ops 3 Salvation DLC releases on Xbox One and PC. For all the zombies players who are feeling nostalgic or want to see where the zombies storyline originally started, Xbox Live members can now download Call of Duty: World at War through the backwards compatibility program.
