Is it really just an add-on

Man has to be clear that it is not a new game in the true sense but only an extension. At the beginning I was really excited about the creepy atmosphere but is quickly lost again once you get the hang of and represent the zombies for reasonably experienced players do not call values ​​challenge more. Then there is the playful forth quite monotonous. Saved the whole thing is the (as always with Rockstar Games) outstanding hiss Sequenze in which the abysses were showing in the still living.
Compared with other add-ons ranked RdR Undead Nightmare in midfield. It is much better than for example the extensions to Mafia 2 but it does not come to "The Ballad of Gay Tony" or "The Lost and Damned zoom".
