The game’s gang Headquarters side-missions bear a striking resemblance to the Fort liberation missions in Assassin’s Creed III and require you to enter a restricted area of the map, identify and kill the leader of its inhabitants and complete a couple of other varying tasks to complete. These side-tasks will be unlocked and available to undertake once you have completed memory sequence 3-01 ‘The Colour of Right’. During this mission you will actually liberate the Waterfront HQ in New York, so you do not need to worry about that one anymore!
Capturing each Headquarters will not only reveal a large section of the surrounding area on the map similar to viewpoint synchronisations, it will also give you a fast travel point and a small base of operations similar to the Captain’s Cabin on the Morrigan.
There are 10 headquarters located around the game world. You will find one in the North Atlantic, three in River Valley and six in New York.
Entering and completing all of the Headquarters will earn you the achievement/trophy ‘Capture all Gang HQs’.
