Briefing: Sadonos "Pandora Tomorrow" phone call is being forwarded through an encrypted relay in the communication system of a submarine docked with in a supposedly abandoned shipyard. Infiltrate the submarine and access the communication system to further trace the call.
Objective: Infiltrate the caves.
Turn on night vision or thermal vision as you move forward. Theres a guard patrolling this area and hes difficult to spot unless you use an alternate vision mode. Grab the guard when hes the farthest away from the enemy camp. That way the enemy in the tower doesnt see you. Grab the patrolling guard and drop him in the dark.
Approach the camp from the far right side so you can use the old truck as cover against the guard in the tower. Move around the right edge and approach the turret under the tower. Disable the turret using its controls.
Move into the alley behind the tower and switch on your thermal vision. Trip wires trap this alley area. Approach the blue circles marking the trip wires and disable the danger. Move into the next hut and move to the right. Spot the patrolling guard ahead (theres also a second guard in the area). Remain in the shadow and lure him into the dark with a whistle. Punch him out and drop him in the darkness. If you have trouble getting both guards, shoot out the light on the right fence and dont hesitate to use some of your weaponry like sticky shockers and ring airfoil rounds.
Move into the hunt on the far side. Be sure to avoid the guard in the tower above by shooting out the light if you didnt before. Sneak around to the left and spot a couple guards at a table. Use a diversion camera and fire it on the far left wall. Position yourself that youre in the shadow so the guards dont see you when they investigate the camera. Gas one of the guards (or both ideally) and finish off the other with one of your weapons. A third may be alerted to the scene; lure him into the dark with a whistle and drop all bodies in shadow.
Continue into the next clearing and toward the stream. Enter the narrow alley adjacent to the stream and perform a split jump. Pull yourself up onto the right ledge. Shimmy over to the opening and enter quietly. Theres an enemy below you. Move to the right side of this platform and drop down onto the crates. Sneak up behind the distracted guard and disable him. Move his body to the darkness.
Quietly move to the left side of the exit. Spot the guard outside shooting his weapon. Take him out with a sticky shocker or lure him inside with a whistle. The turret across the clearing is live. Toss a flare on the left side of the clearing and watch the turret fire away. Move to the turrets right and find the controls. Deactivate the turret. Move the body into the dark if necessary.
Approach the hut behind the turret. Before entering, switch on your thermal vision to see that lasers protect the interior. With thermal on, time your advance through the lasers. When a laser reaches its peak, move to the next one. Repeat to the end and descend the ladder into the next area. Take the lift down.
Exit the elevator. Search the storage room on the right for a medical kit. Move into the shadow and listen to the patrolling guards. Turn off the lights using a switch on the left wall (find it by searching across from the supply room). With the lights out, taking out the guards becomes much easier. Flip on night vision, lure one close and grab him. Repeat until both guards are disabled and in the dark.
Enter the office on the right side of the hall by going through the double doors. Move around to the back end of the room and find the technician. Grab him--dont kill him--and interrogate him. You need him to raise the submarine. Move him in front of the controls near the window. Use the computer with technician in hand to raise the sub. Another technician radios in. Before the mission is blown, use the computer again to force the technician to make up a quick story. Hit the tech and leave him in the dark.
Exit the office and go around to the right side. Approach the door to enter the next area. Move up the stairs and shoot out the light above the door. Use an optic cable to spot dangers on the other side of the door. Open the door and whistle to lure the guard inside the dark room. Disable him.
