Thanks to Locastan for the pictures!
Arctic was strongly reworked. The popular south base camp position on the cliff above the base is practically gone – bushes were removed. North-western base was also reworked, now there is a hill obstructing the view. New paths opened for attack.
Tundra changes – the west is quite different now, didn’t test.
Komarin – a lot of bushes was removed, the map is flatter, more accesses and the infamous camping forest in the corner disappeared. The map now has less cover, the “villages” are denser.
North-West – the northern path got reworked, it’s much more open now.
