The world of Red Dead Redemption was always tough, but at least the dead stayed dead. Not any more: the deceased are on the prowl and swell their ranks when they nibble on John Marston's skin. Cue more than seven hours of new single-player adventure as he travels across New Austin and Mexico searching for a cure for the zombie plague, killing just about everything along the way. Not to mention meeting old friends, rescuing survivors, clearing settlements of the undead horde, picking up devastating new weapons and taming all four horses of the Apocalypse. Don't worry that it's utterly ridiculous, because it's also completely brilliant.

If that weren't enough, this disc bundles together both the Liars & Cheats and the Legends & Killers multiplayer add-ons, so if you do ever tire of popping zombies in the head, you can play new maps, games and characters online.

Undead Nightmare is still recognisably RDR, albeit with less ammo. Not that you'll ever run out if you get busy with your trusty torch or once you get your hands on the blunderbuss: it uses bits of zombie as shot and there is no shortage of them…

The single best thing about this game, however, is that you play it all as John Marston. Which is a very welcome return from the dead.
