GamerNode: "Over the past few years, Rockstar has shined in the DLC department. Both downloadable episodes for Grand Theft Auto IV were fantastic, and the multiplayer additions to Red Dead Redemption have been solid. But with Undead Nightmare, they are finally capitalizing on the single-player portion of Red Dead Redemption. This zombie-filled adventure features a six-plus-hour story arc in addition to new weapons, new mounts, and even a couple more multiplayer modes. Rockstar may be a bit late to the zombie party, but the quality and care behind this latest offering once again show us how DLC can be done right."
