no Rockstar hasn't released undead free roam but some rumors have gone around that they may release it as an update and you must own the undead nightmare to play it lets hope this is true :D
only if u have XboxLIVE
Just go onto multiplayer and join a free roam session.
Go into multiplayer free roam press select then go to undead
i have played a few but by far my favorite is undead overrun on red dead redemption: undead nightmare
yes the multiplayer works but the single player is only undead nightmare
You essentially go into free-roam. You get the last horse of the apocalypse "Death" and a chance to complete any challenges/stranger missions you haven't completed yet
No! Directions 1. Go To Free Roam/Multiplayer 2. Press Select 3. Scroll All the Way Down 4. You should see it. P.S Theres other zombie modes to.
its on Undead Nightmare
First purchase the Undead Nightmare DLC pack then head to a location with a land grab marker (These can only be found in PVP free roam) If you don't wish to purchase the Undead Nightmare DLC pack you can always wait for someone who does own the pack to initiate a land grab. Hope that answers your question.
No you can not
I don't think Red Dead Revolver is, but Red Dead Redemption is.
You cannot get Red Dead Redemption - Undead Nightmare on the PlayStation Portable.
