The best zombies map of all time: Kino der Toten, Black Ops 1.

To me, it's as good as it gets. It was originally supposed to be in World at War but it was cut due to time constraints. Thankfully, Treyarch was able to finish it up, polish it up, and release it with Black Ops, cause it was good. Really good. So many iconic weapons. Layout was a perfect blend of simple and complex and the enemies were all unique and fun to fight. Plus, Kino had some of the best music in any COD Zombies map ever which made it even more addicting to play through and grind over and over. Call me old school, but I think Kino is the absolute best zombies map ever released and I could play it a million times without ever getting bored.
