Go on to xbox live and download it. You will have to have a bank, credit or Microsoft point card ready to purchase it. Alternatively buy the disk.
No. Undead Nightmare standalone disc is the Undead Nightmare, Legends and Killers and Liars and Cheats packs (possibly Outlaws to the End too) + Multiplayer. There's a possibility your multiplayer lvl from RDR carries over when using the UN disc. I do not know as i have RDR and the UN download for Xbox but the UN disc for PS3
