I thought the launch map was great, the second map I thought was awful and dropped off the game after that.
Zombies on black ops 4 I enjoyed more on the whole though.
And vanguard zombies is pretty awful sadly.
First and second..? What do you mean, there was like a ton of modes and maps..
Dead Ops Arcade (+ several modes)
Die Maschine
Firebase Z
Forsaken
Mauer Der Toten
Plus additional modes I don't remember the name of at the moment, like the Playstation one
Outbreak maps
Alpine
Duga
Golova
Ruka
Sanatorium
Zoo
Collateral
Armada
Plus additional variations, objectives and stories within.
These, especially Outbreak's "open world"-like experience gave me some of the nicest coop experiences I've had in a long time.
There is lot of good content in the mode, so no wonder why many zombies fans have been asking for a standalone from Treyarch to give them more room to flesh it out even more.
As for Vanguard, yeah, let's not speak about that sad story.. fuck me it was bad..
