One of those details is the release date. You can expect the zombie invasion to crawl onto consoles on October 26 via PSN and Xbox Live.
But that's not all. Rockstar will also be releasing a stand-alone disc called 'Undead Nightmare', which bundles together the Undead Nightmare Pack, the Outlaws to the End Co-Op Mission Pack, Legends and Killers, Liars and Cheats Pack and all the Multiplayer Free Roam modes released to date
If you don't want the whole kaboodle, the Undead Nightmare Pack will be available for 800 Microsoft Points or £7.99 from the PlayStation Network.
"Undead Nightmare turns the world of Red Dead
Redemption upside down," said Sam Houser, founder of Rockstar
"The supernatural vibe and the return of some favorite characters creates a whole new game inside an already incredible world."
