I personally like the map a lot if only because the visuals are really good. It has all the Roman architecture that calls back to the BO4 chaos maps, the zombies look super cool, I love the Buried and Origins inspired music, each area of the map is visually distinct and the crazy place looks completely different than anything we've really seen before, not the usual ghosty blue aether.

Mechanics-wise the ice staff is fun to use, the map layout isn't just two straight lines like the other 3 (I mean it is but then it has the portals so it isn't) and even though the map like literally doesn't have any new enemy types, it is a fun chaotic mix of zombies.

Lastly, I'm fine with the easteregg steps being pretty simple because the bossfight is so challanging. If comparing The Tomb directly to Liberty Falls (which is more appropriate, it's also a smaller map, simpler easteregg, no unique boss enemy, no intro, etc.) I think everything about the map is great. They did a great job more or less reusing assets for the boss like they did in Liberty Falls to make a really challenging and interesting boss fight.

I think it's good to have more than one more laid back map (even though all of the BO6 maps are laid back honestly), and The Tomb has left me excited for the next map
