No because Undead Nightmare is essentially a whole different game. You can only play as his son Jack at the end of the regular Red Dead Redemption.
It's seperate to the original Red Dead Redemption. You can tell straight away as John Marston is still alive.
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
It is not known but i assume around 20-ish.
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.
For the game of the year edition you get both the original Red Dead Redemption, and undead nightmare.

You can't play coop on Red Dead Redemption or Undead Nightmare.
You cannot get Red Dead Redemption - Undead Nightmare on the PlayStation Portable.
