Long have the Dwarves lived and prospered in the Grey mountains of the north pestered by goblins and dragons.
This is a mighty 2 player fortress map for the dwarves. Two inside the fortress-mine and two outside besieging it. There are three entrances, one for each player inside the map called the local gates and one joint controlled by the two players inside called the main gate.
There will be ledges and towers to use to protect your entrances. Use them well! The mine and fortress complex is simply large. It will be a challenge defending ALL of it.
I suggest a joint multiplayer defence against two other players or two brutal Mordors. It is also prefered if the defending players are both dwarves.
