These are available during Sequence 5 and after. They are NOT needed for the Complete all Mission Constraints
achievement (strategy is given for full synch anyway for completionists). This achievement has 3 missions:after Sequence 5 begins
says you can encounter this one between Sequence 3 and 4)
1. MISTRESS AND COMMANDER
- meet the down-and-out Captain Dominguez on the dock southeast of Gerald's warehouse (4th dock from the right when viewing map). After his request, go north to the red marker (you automatically switch to Unarmed when you get near the target area, do not arm a weapon). Switch to smoke bombs and drop one near the target. Beat the target up and his 2 guards who also get affected by your smoke. Loot his prone body for the deed to a ship. Return to Dominguez for mission completion.after Sequence 5 ends
2. THE CANNON
- find a pigeon coop close to the city wall a bit north of your family mansion. When mission starts, climb the city wall north of you and follow it west toward the military camp/fort. You will go through two covered areas. When you get to the third covered area, look through the doorways and watch the patrolling guard walking the wall. When he turns away from you go to the door and look left for another guard on a roof above you. When he turns away, run behind him and down the roof dropping to a lower roof. Hop to other structures to the right and jump/climb the wall of the main building where the red marker appears. Don't mind the guards bustling about your presence; if you're quick, they won't matter (just don't kill anyone for full synch). Shimmy left around the corner and to the 2nd floor walkway. Hop the railing and head to the chest over another railing. Loot the chest and rush back the way you came. Get back to the wall and run through the covered area to escape and get mission completion.
*this is how I did this mission. there are several ways to go about this if you'd rather find your own way*
3. BEFORE THE MAST
- meet your third potential recruit near the docks east of where you met Dominguez in Part 1 of these missions. This guy wants to test your speed and parkour skills. This video helped me a lot (for full synch, you can't take damage): NegativeCreep08
suggests: "My advice is run past the first guard, shoot the second one but stay on the rooftops after the 9th orb and instead jump across and hang on the small branch with leaves on it (at the 1:46 mark)"Smoky Brenneth
suggests: "I used the slave persona and just smoke bombed the two guards you encounter."
