Super hyped for the new Cache, i hope we get it in the competitive map pool after Austin.
I like the idea of making it more similar to the original one, while keeping some good changes from the first rework, like the open rooftop in checkers or the gap in connector that now is just for nades.

I also love that squeaky door is now nadeable, please keep that.
I really dislike instead that fire barrels damage you. I wouldn't keep that kind of mechanic, especially considering there are so many of them.
Also maybe what about making the stone walls in connector and car (the one to self boost in highway) climbable from both sides, not just one?

As a lot of people have already mentioned, there are several fps drops. I have a high end pc but even i sometimes suffer from occasional lags, and gpu is forced to 100%, pretty much in the whole map but in particular i noticed it in ct spawn, mid, and b site, or places with lots of lights and objects.

I made a video searching for gaps in geometry, skybox, wallbangs, etc, i didn't actually find any gaps, but there are some props located in certain places that don't really look polished, and i noticed how it was created a weird fog effect at the bottom of the floor outside the map, probably as it's set in Chernobyl and it's there to act as radiations...but sometimes from long distances this seems like huge gaps, or in my opinion it's just a weird effect:

Timestamp:
0:00 Incomplete brick wall that looks like a gap
0:24 radiation effect blue line a bit weird to watch, maybe make it more faded and less a straight line?
0:43 From t spawn that looks like a big gap in the world, again due to the blue fog effect
1:02 beyond the tree and the stone wall that seems like a gap
1:14 Where i'm shooting is a polygon that seen from there i think it creates a weird effect, maybe the upper line is too straight
1:26 This place from sunrise seems unfinished, i know it's not, but i don't know if it creates a good effect having the brick wall end there.
1:30 Jumping from b site there really gives the idea of gaps beyond sunrise
1:37 from mid boost, that seems like a gap, again, because of the fog effect, but all these really seem like holes
1:48 this is nothing but i noticed the wall there is not closed. No gaps outside the map but maybe seems a bit ugly, having the wall separated.

But overall the map is great and I can't wait to play it in publics soon!
