Searching for a mod (from AntiElitz Nov DangOreus stream)

[JohnyDL]

Last week AntiElitz did a subscriber event with DangOreus mod, but I can't seem to find a list of the mods he used.

The one I'm specifically looking for was to unlock new areas on the map required filling that square with a certain amount of pollution

I tried a bunch of different searches and I can't seem to find the mod that did that on the portal, the only one that was remotely similar was Territory Claim, but that doesn't keep the fog of war in effect (and stop biters) until the area is unlocked. So any ideas folks? Or is this something Vanilla I could configure if only I knew how?
