The starting door for the attackers is the Boarding Axe in the W side of the map. The additional doors are the two swords in the mouths of the north and south channels.
The starting door for the defenders is the Round shield in the main channel, with the additional unlockable doors each guarding an exit from the north and south channels
The default wind blows from the NW favoring the main and northern channels, while the attacker bonus wind blows from the SW, favoring the main and southern channels.
Since the Fortress sits on the edge of the big island in the bay, it uses Fort Cruz as the setting.
Should you make it past the Fortress, and chase off the Defenders, you’ll be doing battle in the narrow streets of French Town.
On this map, the attackers have the option of sailing into the large main channel, directly into the defenders initial spawn, or taking the longer side channels which give more direct access to the Town.
