Red Dead Redemption: Undead Nightmare

Undead Nightmare is an absolute gem, and more people should play it. If you’ve never played the original open-world cowboy game from the creators of Grand Theft Auto, Red Dead Redemption, don’t worry, as this game serves as a “What If” situation.
Undead Nightmare tells a unique and involved story in the traditional Rockstar fashion, but at the same time, if you’re just looking to kill hordes of zombies as one of the best gunslingers ever to live, that’s on offer here too.
