Easily the best dlc of any COD game, and I doubt that'll change any time soon. When I was really young, I played a ton of COD, but the only thing that really ended up sticking with me was zombies. I enjoyed a few of the campaigns, and the multiplayer in most of the games was solid, but my group of friends and I eventually reached a point where BO1 zombies was all we played. What started as an easter egg that a few of the WAW devs made for fun, eventually blossomed into an outlet for creativity to a degree that wouldn't make sense in the standard gamemodes. I hadn't played any of the games since BO1 on 360 before I found out this existed, but this was an obvious buy on sale, even though I'll never touch the rest of BO3. I've got a lot of great memories tied to 7/8 of these maps, and for me personally, this is COD's legacy
