The Map is probably like a 5/10 for me (destroyed nuketown is cool, fixed nuketown gives me uncanny valley vibes for some reason) but the quest is honestly fun, even with some of the goofy steps like the hopscotch. I managed to solo it first try without fail, and then helped a public match complete it (the ads are mean on co-op) without fail again.
The fact its 3000 points to travel back n forth though is absurd, especially with the Sundergat steo and the Tree.
Also, of course the sound department fucking kills it. Come Back Down is probably in my top 10 Zombies songs and the boss theme is fantastic (anyone know the song when finishing the piano step?)
I have to say, I'm not AS disappointed as i thought i'd be
