Cave has only one small entrance.
I don't really see the point, like bases are not visible anyway.
Was planned different, back when the maps have been created. Will maybe change again some day in future, don't now.
That could be nice to test bases visible for everyone, though it should have some protection in that way...
Instead of doing TC, big gangs like vacuum cleaners will do personal wipes )))
I don't think so...But the mercs prices would be high as hell : D
