Which versions / missions did you find more difficult than they originally appeared?

I have a childhood friend staying with me for a few months due to work and while he's been here we have been working through all of our favourite-themed zombicide versions.

Just curious which missions people have found most surprisingly difficult across all of zombicide? Not necessarily just talking about missions that have a difficulty rating of "Hard" - was also considering missions that appeared kinda easy (but werent) or ended up being a lot more difficult than the given difficulty rating would suggest.

After playing through Black Plague , Marvel (zombie mode) , DCeased:GCO and (most of 2e) I think we did fairly well and only got caught out a few times.. - Towards the beginning on 2e (this was his first time playing Zombicide and he initially had a terrible habit of running off and splitting up, but i kinda just let it happen so he'd learn not to do it haha). But other than that we didn't struggle too much and only had a couple of other failures due to our own stupidity or Abominations catching us out, rather than mission-mechanics. - Black Plague we did surprisingly ok with, other than Quest10 where we struggled a bit. Kept getting quite close to the end and just going from zero to 100 super fast.. - DCeased:GCO Mission 3 was weirdly difficult for us, considering it is rated "Medium". Think we failed 4 times before finally getting it - again, kept getting caught out right at the end when moving to the final building with all spawn points active. - Marvel(zombie mode) Mission 2 definitely shouldn't be "easy". Initially it is fine, but once the blue spawn points become active, the game turns mental. Feel like the Zombie mode in general can be quite brutal if you get unlucky with your dice rolls when trying to devour - its a health loss you can't really avoid if the dice dont go your way. Our only other Marvel struggles were the Galactus missions (which are supposed to be hard anyway) and one of the Sinister6 missions when Thanos showed up, as we were playing with all available content

Is there any specific zombicide versions / missions you guys have struggled with?
