Why don't you guys open one of these mines. This is such a gem, and it has been 10 years and you still havent used it. WHY? You don't even need new assets, just make the entrance openable, edit a bit inside part so it would have faces, make a tunnel (400-500m, maybe few side turns/additional small tunnels, not too long to not piss off land designer guy, and editing the entrance not gonna take much time too). You can use rocks for walls and planks from time to time, place railroad, few workbenches, add sound points, darkness - that is it. Can even be without loot (or if you want c4/detonators or other industrial loot). You'd have so much benefit from it, but don't trust my words, try it instead. If you think close to shore will not work - open one in NWAF, or on Linvonia (it is far south there). When 1.23 was about to release I was SO exited about that you gonna open those 2 entrances on NWAF, but sadly... I mean you know by yourself what boost Dambog gave to the game. Mines aren't gonna boom same hard, but still, underground closed spaces with right sound/story/props... The right mine in the wrong place can make all the difference in the world (if you know what I mean). Anyway, it's up to you, but you'd benefit a lot from it if you had decided to make it happen.
