Sentinel

You and Ilona are taken to a hangar area, where Cormack is giving a briefing on the current misison. Follow Cormack as he grapples up the cliffs, cutting through the waterfall to reach a higher point on the right. A few more ledges lead you to the private estate.

After marking the guards below, grapple over to the railing, and wait for them to pass.

Move in toward the bushes ahead, and whistle to get the lone guard’s attention. When he gets close enough, a grapple icon appears on him. Press the button to perform a concealed kill.

As you negotiate the estate grounds, the way you go and the enemies whom you take out can vary greatly. This walkthrough gives you the option with the fewest number of confrontations.

As you move through the area, use your Target Tracker on anyone you encounter. Turn left toward the objective marker, and grapple over to the planter. Wait for the guard ahead to move away, and quickly hop the rail into more bushes.

As you continue forward onto a rooftop, watch the drone on the left. If the detection meter appears at all, move back into the brush. Move forward, and then grapple to the rail on the right. Watch the nearby guard’s movement, and then move over to the left planter.

Grapple up to the roof of the security building ahead, ducking down to avoid being seen by a drone that emerges from inside. Step over to the bomb highlight, and plant the EMP. Once inside, access the security system. You only have two minutes to complete the task and get out, so be quick. Once done, immediately grapple out the way you came in.

Back outside, turn around and move over to the ledge just ahead. Follow it around to the left, and drop into the foliage at the far wall.

Two enemies occupy the balcony ahead, with a drone patrolling the left perimeter. Wait for the far foe to move away, and perform a Grapple kill on the other. Immediately duck into the bush on the right.

When the guards and drone are not looking, continue into the next planter, and then grapple up to the shelter around the corner. Cautiously grapple over to the garage rooftop. There are many guards, civilians, and drones around, so target as many as you can and watch their movements.

Look over the garage ledge toward your destination, and spot the patrolling drone and the pool below. When clear, grapple down to the right ledge. If you duck underwater, a second drone shows up to scan the water. Before it arrives, quickly grapple to the upper balcony.

Step inside to meet up with Cormack.

Access the computer on the desk.

Move around the shelves, and eliminate the two men who enter the hallway. Follow Cormack down the elevator shaft. A third and fourth guard come in after you.

Stand next to your partner until he instructs you to move. Step behind the vehicle, go prone, and crawl underneath. When you come to a stop, move into the hangar next door.

Follow Cormack up to the top of the shelving on the left, and drop behind him to get into position. Step up to the railing, and record the meeting.

Grapple up to the top of the storage racks. Follow Cormack down to a walkway, up the stairwell, and out the exit.

Several enemy soldiers and a couple drones attempt to keep you from reaching the plane. You can spend a little time fighting from behind cover, but it is best to simply hightail it to the aircraft. Use your Grapple to reach the railing quickly, and then attach to the wing as soon as the icon appears underneath.
