A devastating landslide destroyed the village of Bleeding Mark and left survivors trapped in the rubble. Without your help, they won’t be able to escape the Snapjaws that are waiting for them underwater. The time has come for the Messiah of Meridian to stay for the day. This is how you complete the side quest The Deluge in Horizon Forbidden West.
You will need to find this side quest by exploring its location. It will automatically be given to you when you find the destroyed village. Head north above the Greenswell Rescue Contractor. You will find the village in an extremely watery area. and was assigned the task of investigating. You will spot several machines in the distance. Take them out to continue.
During the fight, you will likely hear some survivors screaming for help. They were stuck on a watchtower with no way to get down. Go to the big crane in the area. You will need to get the crane into position so that survivors can use it to get down. Start by clearing debris with your Pullcaster. Then jump into the water to the left of the crane platform to kill some Firegleams.
Once they’ve been taken care of, go to the platform opposite the crane. Climb up the small tower there and use your Pullcaster to clear the wreckage on the crane arm. This will give you access to the ladder on the crane. Climb onto the crane and shoot the rope holding the arm up. This will cause the arm to drop onto the platform the survivors are stuck on. They will tell you about survivors who need help.
Head over to the west side of the village to find a broken tower with many survivors trapped inside. You need to find a way into the building. Push through the tree to enter the tower. After that, the climbing path inside is quite simple. Reach the top of the building and jump to the other side. Jump through the hole with the ladder to land where there are survivors.
Talk to the survivors and you will be tasked with finding a way out. Use your Pullcaster to pull down the beams inside the building and remove the vent. Then the survivors will be able to go out and the goal will be completed. Go talk to Natikka to get your last item; rescue Kentok.
Clear the debris in front of The Gouge and head down the mining shaft on the other side. You will get a cutscene at the end where you find Kentokk. After the cutscene, use your Pullcaster to climb up the beam and get to the vent. On the other side of the vent, use your Pullcaster to bring a box down and continue forward. Climb onto the mine shaft, using your Pullcaster as needed to open a wall or two. Eventually you will find some Firegleam on the wall, destroy it to flood and rescue Kentokk. After the cutscene, the mission will be completed.
