The key to Ada's missions are stealth, since she is not capable of dealing with never ending enemy spawns. Open the door and walk down the corridor and take cover on the wall at the intersection and stealth kill the J'avo. Continue straight, ignoring the yellow lasered doorway, and crawl through a short corridor to the other side.
Carefully walk to the corner nearby and take cover to stealth kill another J'avo. There is a J'avo on the other side of the yellow lasers that can see you, so wait until he walks away and enter the doorway to the left of the lasers. Crawl under a gap in the sleeping chambers and stealth kill the J'avo on the other side before slowly advancing to the door, where that pacing J'avo is. Wait for him to walk away and rush in for a stealth kill to proceed.
Continue slowly to the next yellow lasered doorway, peaking around corners to make sure you are not seen. When you reach the doorway you'll notice that a J'avo paced the area behind the lasers and there is no way to get by without being seen. Pull out your Crossbow and take aim at his head when he stops for an instant kill.
The room to the right of the lasered doorway has a J'avo that does not set off the alarm, but he does mutate if you fail to kill him in one hit. Take cover and aim for his head. If you fail, and he mutates, use a Quick Shot to pin him down and finish with a melee attack.
Enter the crawl space on the other side of the room and crawl to the other side of the laser beams, collect any items and jump down to the next level.
Continue forward, using Ada's grappling hook, and peek around the corners for more stealth kills. When you reach the trio of J'avo, you will be forced to become noticed the minute you kill one. Take one out with the Crossbow and then throw an Incendiary Grenade in to finish off the rest. Break the crates nearby for items and then continue.
You'll come to a hall where two J'avo pace back and forth and another hides in a room. Take the one in the room out first and then deal with the two in the hall, killing one when the other is walking away. Break all the crates in the area for items and then continue up the stairs to a small bedroom on the right that has a Serpent Emblem on top of the cabinet.
Continue to the next crawl space and drop into the fancy puzzle room.
Start by examining the button by the door to note that it is locked and then head behind the partition and look through the opening. It is blocked by the horns of the goat on the other side, so go around and examine it to move them. Return to the opening and look through to see an image within the painting (Snake, Fish, or Eagle). You must now go around the room and examine the four consoles to change the image on the doorway's display to match the animal in the painting. Once the image matches, examine the door to proceed (if it is incorrect you will get a light shock).
The next area has turrets that take out the J'avo in your way. Walk down the hall and step on the glowing floor to activate the turret and destroy the J'avo and continue to the projection room.
Grab the Red Herb, Green Herb, and Incendiary Grenades x2 before you watch the projection. When the video finishes, you will be ambushed by some J'avo that can be taken out with a grenade. Finish off any survivors and then exit the room and head right into the newly opened area.
Deal with the J'avos or run back and straight the the glowing red light to lure the J'avos to their death and continue. Run to the end of the hall and kill the two J'avo that drop down and then climb up into the vent.
Drop into the next area and you'll see a glowing white panel for a turret in the area below. Head rown and activate it and then continue forward toward the crates to lure the enemies into the turrets fire. When then start to head over the container, rush back and around the corner to another turret activation. Grab the 9mm Ammo and any items dropped by the crates and enemies and then head around the corner.
A J'avo is controlling the ground turret that prevents you from moving forward. Crawl along the first container and when there is a break in the fire, rush to the other side of the room and grab the Green Herb before hoping over and activating the glowing turret trigger. Once the J'avo is dead, break the crates behind you and move forward to the reactor.
Submarine Reactor
Open the door and walk left to the end of the room and turn around to find a Serpent Emblem. Break the two crates in the room and jump down to grab the Assault Shotgun. Turn left at the intersection and quick shot the Glava-Smech with your crossbow and finish it off to grab the crate. Turn around and kill the J'avo that has likely headed your way, if he saw you, or kill him with a headshot. Continue down the hall for another J'avo and make your way to the ladder.
The reactor room has a bunch of J'avo with guns that like to shoot from a distance. Rush in and take them out or take them from cover with your Crossbow, but ignore the two J'avo at the far end of the room that can not reach you. Grab all the items from drops and crates and then shoot one of the J'avo on the far side of the room for a cinematic.
Grapple your way to the upper level from the metal walkway at the back of the reactor room and head through the door. Kill the J'avo and break the crate behind the partition and head through the bulkhead to the next room.
Jump across the catwalks as you make your way forward and grapple to the far side. The walkways become unstable and you'll need to dash through the area to reach the bulkhead on the other side. Follow the linear path and grapple up another level and then take out the two J'avo as you continue.
Grapple up another floor to the bay rush forward as sub starts to pitch and roll. Eventually, Ada will fall to the ground and you'll have to crawl with the L stick while hitting X/A to use stamina to move quicker. When you are nearly to the exit, the sub will turn all the way vertical and Ada will be riding a container down. Hit the X/A button when the prompt pops up.
Head forward and Ada will indicate that you need to go up the shaft as the water starts to rush in behind you. Grapple to the next level and then run to the ladder and climb it. Rush forward and jump across the gap to the left and head to the end of the hall to another ladder on your right. Climb it and jump across another gap and take the ladder on your left to a hall with a crawl space at the end.
Go under the crawl space and kill the Noga-Trchanje with the Ammo 50 or Assault Shotgun and turn left. Before climbing the ladder, look right and shoot the Serpent Emblem and then continue up the ladder. Head right and examine the valve to shut off the water by rotating the L stick and then return under the crawl space and continue forward and right to another ladder.
Rush forward and hop down and then dash and slide under the crawl space to the left into the next room where you can grapple up a level. Turn around and run across the mesh grate on the right to the ladder and climb up to another floor with two crates. Run around one to jump the gap and then run to the ladder and head up again. Climb the crates and then use the grapple to reach the end.
Submarine Torpedo Room
Head straight down the hall and defeat the Gnezdo before jumping the second partition, turning around, and melee attacking the Serpent Emblem. Break the crates and then turn around and head back over the partition to the end of the hall where a ladder is. Crawl up both ladder, head through a crawl space and drop into a control room.
Examine the panel and then jump off and head past the panel across some partitions and into a room with two Gnezdo. Ignore them and head left over a partition and break open the crate before climbing up to another crate and another crawl space.
Crawl through to the other side, where more Gnezdo await, and rush to the end of the hall for a crate before jumping over the nearby partition into a room with a Gnezdo and two water filled bulkhead doors. Jump into the right one and swim down, past the ladder, and then out of another bulkhead door. Climb up the nearby ledge and turn on the power.
Return to the water and go back the way you came, across the ladders in the bottom right of the room, and pop out. Jump into the other water across the way and follow it to the other side where you can kick the doors open. Jump over and climb the crates to enter the crawl space and exit into the torpedo room.
Climb back up the platform and actviate the control panel. As the voice of Ada Wong asks questions, J'avo will attack you and try to prevent you from answering questions quickly. Your goal is to take ake out the enemies with the machine guns first and leave the knife J'avo for later while approaching the panel, from either level, and hitting O/B to answer questions. If you manage to turn an enemy or two into the explosive bugs, leave them alone and stay on the upper platform (they can't jump up). Once all 5 questions are answered, the camera angle will change and you can grapple up and finish the level.
