Assassin's Creed 4: Black Flag Walkthrough Part 25 – Sequence 4: “Overrun and Outnumbered”
Optional Objectives:
Use 8 Sleeping Darts on guards
Use 2 Berserk Darts on guards
Follow James forward as something is happening back at the encampment. The Templars have begun making their move on this Assassin Camp. The Mentor puts it on Edward head though James volunteers to help deal with the invading forces.
James will give Edward the Blowpipe. This comes with a small stock of both Sleep and Berserk Darts. Follow prompts to fire off a Sleep Dart at the Soldier passing below you. Run and perform a leap of faith in the palm leaves below you.
Once on the ground, head straight across from the cliff and climb the nearby wall. You will find a captured pirate that has 1 Soldier guarding him. Put him to sleep with a Sleep Dart then knock him out to keep him out. Free the Pirate and then climb back over the wall.
Follow the wall over to the right and duck into the nearby Stalking Zone. There you will find a view of the next plaza. There are a number of prisoners below with Soldiers watching them. Look up and a bit to the right to spot the Gunner. Either sneak up on him and take him out or just hit him with a Sleep Dart and then knock him out. Either way, climb up to the overlook after and use it to hit the Guards with Sleep Darts then either knock them out or kill them. Now free the Assassins in the Plaza then head up the stairs in the small shrine to free another prisoner.
Head to the North and go to the roots. Watch the nearby Soldier and wait for him to turn around from the nearby stairs. When he moves away, climb up the stairs and duck into the Stalking Zone. Wait for the Soldier to come back and take him down from there. Free the nearby Pirate after that.
Go over to the West and duck into the Stalking Zone nearby the stairs going down. There are more Prisoners there you need to free. Hit the Gunner with a Berserk Dart and watch as he goes at the Soldiers nearby. If there are a few survivors, then use the Berserk Dart again, if just one then use the Sleep Dart so you can easily deal with him. Free the nearby assassins and follow them up the Shrine that is nearby. Head over to the Synchronization Point and synch with it. Dive off it and head to the North. It is best to pass through the Shrine itself then duck into the nearby Palm leaves at the Northern end.
At the Northern end you will find another prisoner with 2 Soldiers watching him. One patrols around the Prisoner while the other watches from above. Lure the first one into the palms with a whistle and take him out. Step out of the palm leaves after that and let the other guard see you. This will lure him down. As he descends, hide back in the laves again. When he is close, whistle to lure him to the palm leaves and then kill him. Free the prisoner and then start over to the East.
Go to the Northern end of the nearby hut. There are 2 Soldiers ahead of you. Hit one with a Berserk Dart and watch as they kill off the other soldier then go charging into the midst of many soldiers. Head for the post you see coming down from the tree hut above you and climb up it. Get to the Southern side of it and then hit the patrolling Gunner on the next Watch Tower with a Sleep Dart. If you time it so he is nearby a ledge, there is a chance he will simply fall and die. Now head across the tie between the hut and the watch tower and free the prisoner there.
