You can't play coop on Red Dead Redemption or Undead Nightmare.
No, if you buy the one for 20 dollars that is undead nightmare but not the original. The only way to get both is buy the Original Red Dead Redemption and then buy the Undead Nightmare add-on
Well, you can get Undead Nightmare into the Red Dead Redemption disc if you download it from the PlayStation Store.
You cannot get Red Dead Redemption - Undead Nightmare on the PlayStation Portable.
I would say Undead Nightmare is a DLC because you die in The 1st Red Dead Redemption...
Only if you want to download the game, if you buy the undead nightmare disc the no you don't need the original red dead redemption.
You can download Red Dead Redemption Undead Nightmare at the playstation store on the playstation network. It costs ten dollars.
