Red Dead Redemption: Undead Nightmare

Rockstar, never a studio to avoid a parody, has thrown its zombie hat into the ring by introducing the undead to Red Dead Redemption. Undead Nightmare is the first add-on pack that brings a whole new single-player campaign to the wild west. The new story takes place in-between the "home" period of Red Dead Redemption's main plot, and the end of the game itself. That's the time elapsed when John Marston rebuilds his ranch, which Rockstar imagines is a period that lasted several months.

As Marston, your objective is to find a way to stop a deadly virus outbreak that is turning the West from Wild to Feral, while uncovering the mystery as to how it all started in the first place. There are several graveyards dotted around the world map that appear to be the source of the zombie invasion. If you want to progress through the Undead Nightmare episode with as little hassle as possible, you're going to need to seek out these graveyards and use the torch - a new weapon - to burn the cursed coffins that reside within them. This will give you some time to explore the land at your leisure while keeping the overall zombie population low.

There's also a rather large update to the multiplayer side of the game too, with two additional modes - Undead Overrun, and Land Grab - taking up most of your online time. Undead Overrun is a co-operative mode where you and up to three friends have to survive waves of undead enemies. The action takes place on one of several new multiplayer areas, each featuring a creepy graveyard to hold yourself down in. Red Dead Redemption: Undead Nightmare is hellishly addictive.
