A post on the Rockstar Newswire notes that all versions of the game will work with the Xbox One, and that if you missed Undead Nightmare the first time you can grab that from the Xbox marketplace for $10. The multiplayer expansions adding new skins and the like are free, however. Xbox Live Gold subscribers can get the base game on sale for $3 off the normal $10.49 price at the moment. It's time to saddle up, y'all.
