Slated for fall, the Undead Nightmare Pack is a mostly single-player campaign tasking John Marston with finding a cure fort a "highly infectious zombie plague that has spread across the frontier".

In addition, pack also features new gameplay mechanics, weapons, zombie animals, mythical creatures and a brand new secret location.

A new multiplayer mode will also be included, with Rockstar promising more information on it soon.

The Undead Nightmare Pack will be available simultaneously for download via PSN and XBL for $9.99/800 MSP.
