Drowned Hopes Walkthrough | Horizon Forbidden West
This guide shows the complete walkthrough of the “Drowned Hopes” Side Quest in Horizon Forbidden West. You will get this quest by talking to the Carja Scholars in Carja Camp at the location marked in the picture below.
Go to the Dig Site
After talking to the scholars, go to the dig site southeast of Carj Camp as shown below. Defeat the machines in the dig site.
Investigate the Submerged Ruins (Console Locked)
An underwater investigation site will be marked on your map as shown below.
Dive underwater and you will see a console blocked behind some wire mesh. Swim counterclockwise as shown in the picture below and you will find an opening underneath the rocks, from where you can reach the console. Examine the security console and then take the vault key. You will need to have unlocked the underwater breathing mask by completing the main quest 11 (Sea of Sands), to be able to examine the console. If you have not yet got the mask, then you will get a “Console Locked” message and you won’t be able to complete this objective.
Go to the Coordinates for the Console
The location that the coordinate will be pointing to will be marked on your map as shown below.
On reaching the location, you will be able to see two objective markers pointing to two different underwater ruins as shown below. You will have to search for a Security Console in both these ruins.
Seach the Ruins for a Security Console (Devils’ Slide)
Devil’s Slide is at the location marked in the picture below.
Dive into the water at the location shown below. Then turn around to see the Devil’s Slide door as shown in the second picture below. Pry open this door and go inside. Then swim through the door on the left side. Pry open another door on the left side here. In this room, you will find the second console. Examine the security console and then take the vault key.
Seach the Ruins for a Security Console (Dread Bluff)
Dread Bluff is at the location marked in the picture below.
Climb the wall as shown below. Then turn right and jump down the elevator shaft into the water below.
Then climb up the ladder and use the ledges to enter an open vent as shown in the picture below. Drop down from the other side of the vent to find the third console. Examine the security console and then take the vault key.
Go to the Coordinates for the Vault
Go to the location shown in the pictures below and dive into the water.
Then follow the blue glowing plants to reach a crack on the wall as shown below. Pry open the wall and swim to the next area. Go up to the surface here and proceed forward until you reach the vault.
Search the Ruins for the Mobile Cover System
Enter the ruins and you will find a locked door. Use the three vault keys to unlock the door. Then go inside and pry open the cache to get the Mobile Cover System prototype. Return back to Carja Scholars to complete the quest and get the “Guardian Tripcaster” weapon as a reward.
