I played the Undead DLC at a friends house and I liked it. It has two elements that has been rarely used: Zombies and The Old West, and it just keep the theme going throughout. I do love the new weapons like the Blunderbuss and mounts, which are mainly just the Four Horses of the Apocalypse. Seeing all the characters again was a blast, and while I will not buy it as a DLC, I will buy it when it comes out on Disc.
What did you guys think of it, or, if you haven't played it, do you think you would buy it?
