Assassin’s Creed: Brotherhood had the most votes among fans, with more than 50,000 people asking for its inclusion.
One of the most popular and critically-acclaimed entries in the series, Assassin’s Creed Brotherhood shifted the action to Rome when it was released back in 2010.
It also introduced multiplayer, not to mention a management system that let you recruit assassins and send them to do your bidding.
If you don’t own the original version, it’s also available as part of the Assassin’s Creed Ezio Collection, which is currently priced at £23.99 in the Xbox Ultimate Game Sale.
Call of Duty Ghosts was the final game to join the Backwards Compatibility list this week, having received 26,000 votes from fans.
