Sequence 12–4: Ever a Splinter

Optional Missions:

- Free the 7 guardian hostages

- Use the Observatory's defenses to kill 4 guards

There will be two level 36 Man o War's blocking the way before you can reach the shore where the mission starts. If you're having problems overpowering them, make sure to upgrade your ship with the best parts you can afford. Since this is the last mission, you should have at least taken time to explore various wrecks and found treasures that may contain blueprints for unlocking the elite parts. Take out both ships then swim to the shore.

Make your way to the forest and you'll find soldiers here. For your first optional mission, you have to free captive guardians by killing their captors covertly. Continue along the forest until you reach the viewpoint. You'll find the first set of hostages there. Continue inside the cave and you'll find two more hostages under the first bridge. Go down the ramp nearby to circle around and take out the guards to free them.

Go to the upper level of the cave until you find a patrol. There will be three more hostages in the deadend to the left. Be careful since there will be two patrols behind the gunners. Prioritize getting rid of the patrols first before eliminating the gunners. After releasing them successfully, the optional objective should be complete. Leave the cave and continue to the Observatory.

In the Observatory, sprint forward, head past the guards, and hop on a large, bright structure on the right. Make your way up these pillars while they are moving, until you reach the platforms at the top. Wait for the pillars to bring you to a beam you can hop over to. Jump through the beams here, until you reach a ledge that gets destroyed under you. Sprint forward to the door to reach the observation room where Torres and his men are waiting.

Avoid getting hit by the beam of light on the floor otherwise you'll get incinerated. Head to the open area to face the guards. For your second optional mission, you have to kill 4 guards using the heat rays on the floor. Keep your weapon ready and counter their attacks. Make sure to throw them towards the wall of light for the kills to count. You have to move quick since if they get killed when they're walking above the heat ray, it won't get counted.

Swing across the metal beams under the platform where Torres is standing then jump to the next wall. These walls will fire heat rays at regular intervals and through fixed lines. Time your movement and make your way to the right then jump on the floating monoliths. Reach the moving blocks on the ceiling and wait on the horizontal bar to get near you. Jump on it and you'll be in range for an air assassination. Don't jump immediately; wait for the heat ray to stop firing and perform an air assassination to complete the mission.
