Find the Elevator and Use the Access Card to Descend Defeat the Soldiers in the Laboratory Clear the First Jail Block Clear the Second Jail Block and Unlock the Cells Escape Sennacherib's Room Defeat Claw Machine

Find the Elevator and Use the Access Card to Descend

You'll find yourself in a Rosetta Research Center. Head forward and to the right defeating the soldiers along the way to get the access card you'll need for the elevator down.

Defeat the Soldiers in the Laboratory

Go through the halls and you'll find yourself in the middle of a laboratory. We recommend using a strong deviant such as Invincible Sun to help you deal with the enemies in the room.

Once the enemies are cleared, check the drops to find the Rosetta V3 Access Card.

Before opening the glass door, open the room near the entrance to the laboratory and follow the hallway to a weapon crate.

Afterwards, exit the room and finalyl open the glass door to get to the next room.

Clear the First Jail Block

Descend the stairs until you reach the bottom of the facility where you'll find a jail cell block. You'll start at the upper floor of this jail, with a lower floor beneath you.

Defeat the enemies, then look for a yellow control panel on the wall in one of the halls of the upper floor. This will open up the double doors leading to another jail cell block.

Clear the Second Jail Block and Unlock the Cells

Once again, defeat the enemies, then look for a yellow control panel on the wall of the upper floor.

This will open up the jail cells, freeing some deviants, but also opening your way out. Find your escape on the lower level of this jail cell block through the large portal door.

Escape Sennacherib's Room

You'll be teleported into a circular jail center. Sennacherib, a large light tower deviant is at its center.

Find the ladder leading down into the lower floor and find another jail cell with another portal in it. If you need help finding it, it is the second cell to the right of the wall that says Floor 02 Unit 17

Red Means Stop, Green Means Go

Mind the light that Sennacherib emits. While it is safe to move when its lights are green, be wary once it turns yellow since it will freeze you in place once the light turns red.

Defeat Claw Machine

As you pass through the portal, you'll find yourself in a long room with a Lv. 20 Claw Machine at the other end. The lights in the room will follow the same rules as Sennacherib's room.

Avoid being out in the open when the lights are red to avoid being vulnerable to damage. After a sixth of its health has been depleted, it'll form a barrier that prevents attacks from outside of it to deal damage.

Enter the barrier and shoot at Claw Machine while the lights are green, and be ready to retreat behind cover once the lights turn yellow. Defeating Claw Machine will reveal the exit of the dungeon. Be sure to grab Hydronaut Fish and your rewards before you go.
