Xbox One users have three additional games to play in the backward compatibility library.
Microsoft added three additional games to its backward compatibility library today: Aliens vs Predator, Kingdoms of Amalur: Reckoning, and Sonic Unleashed.
If you don't already own a disc copy of the excellent Kingdoms of Amalur: Reckoning, you can download the game through the store for $19.99. You can always pick up a used copy too at GameStop, or through Amazon and eBay.
However you decide to purchase it, we totally recommend it.
Same goes for Sonic Unleashed and Aliens vs Predator.
Unleashed is a rather fun game and will run you $14.99 digitally through the Xbox Marketplace. AvP will set you back $19.99 - which is a bargain compared to the $85.49 some folks want for a new copy on Amazon.
