GameZone: "It's no secret that the zombie genre is kind of oversaturated. Still, that doesn't mean zombies aren't freakin' awesome. While we certainly see a lot of the undead these days, there's still room for enjoyment as far as fans are concerned. When Rockstar Games released Red Dead Redemption, it delivered an insanely entertaining open-world gun-slinging adventure. Of course, the studio would eventually shift into a different albeit familiar gear with Red Dead Redemption: Undead Nightmare, a zombie take on the exploits of protagonist John Marston that was a great alternative to the main game."
