Another 4 titles have joined the ever expanding Xbox Backward Compatibility program, including Batman: Arkham Origins (disc version only), Deadliest Warrior: The Game, Disney's Bolt and Fighting Vipers.
Batman: Arkham Origins
(Disc Only)
Arkham Origins features an expanded Gotham City and introduces an original prequel storyline set several years before the events of Batman™: Arkham Asylum and Batman™: Arkham City, the first two critically acclaimed games of the franchise. Taking place before the rise of Gotham City’s most dangerous criminals, the game showcases a young, unrefined Batman as he faces the defining moment of his early career and sets his path to becoming the Dark Knight.
Deadliest Warrior: The Game
DDeadliest Warrior: The Game allows you to choose from history's greatest warriors, equip them with signature weapons and go head to head against the greatest fighters that ever lived. Featuring 5 play modes, customizable warriors and true to life action with interactive environments, Deadliest Warrior is a unique fighting game that is easy to play and hard to master. Severe limbs, decapitate heads and taunt your enemy's lifeless corpse as you build up ranking points with each victory and compete on a global scale to determine who truly is the Deadliest Warrior.
Disney's Bolt
Join Penny and her super dog, Bolt, as they travel the globe on a dangerous mission to save Penny's dad from the evil Dr. Calico.
Fighting Vipers
Fight with flair in the return of Fighting Vipers, the classic arcade game from AM2 that was later playable on the Sega Saturn. Choose one of nine zany characters--including Grace the roller blader and Raxel the metal guitarist-- and break your opponent's costume-based armor to maximize damage. Take advantage of all-new online modes to battle friends across the world.
