Red Dead Redemption is playable on Xbox One thanks to backwards compatibility, and you can get your hands on its multiplayer DLC for free right now.
Available for free are the Outlaws to the End Co-Op Mission Pack, the Hunting and Trading pack, the Liars and Cheats Pack, the Legends and Killers Pack, and the Myths and Mavericks Bonus Pack. That’s plenty of content to get you up and running or back exploring the Wild West.
You will however still need to pay for the Undead Nightmare Pack, a much-loved single player DLC, if you want to play through that.
Like other backwards compatibility games, the Xbox 360 version will be in your download list if you owned the Games on Demand version, or it will download automatically once you put the Xbox 360 disc into your Xbox One.
