This is how to find and complete the Stillsands Tallneck in Horizon Forbidden West.

How to Find the Stillsands Tallneck¶

The Stillsands Tallneck can be found in the very east of the Stillsands. You’ll be able to see it on the map as you approach.

Completing it will open up the entire Stillsands area on the map, which will be very useful for finding the Rebel Outposts and other activities around. It’s recommended to be at least Level 20 to take this on, as there is combat involved in this challenge.

The Stillsands Tallneck is here on the map.

You do not, however, need to have unlocked any mounts or anything to reach it.

How to Complete the Stillsands Tallneck¶

As Aloy approaches the Tallneck, she’ll remark that it looks damaged. Examining a machine carcass nearby will reveal that the Oseram came here and tried to gun it down.

You’ll have to use your Focus to examine the camp. Aloy will realize she has to bring down the Tallneck to override and fix it, and will look around for a weapon to do so.

Around the camp, there are three Ballistas. Using each one of them to anchor the Tallneck can bring it down.

However, it isn’t that easy.

As you try to use the Ballistas, more and more machines will appear to start attacking you and stop you from repairing the Tallneck. You’ll have to fight them off and shoot the Ballistas at the Tallneck in any gaps there are.

They’re fortunately easy to use.

Once you’ve anchored them all to the Tallneck, you can bring it to the ground. At this point, you should have gotten rid of most of the machines and will be able to walk straight over to it. It’s collapsed so much that you can simply jump onto what’s usually its tallest point and override it with your spear.

Once you do this, the Tallneck will be repaired and will stand up with Aloy on the top of it. To complete the mission, simply rappel down.

The map will now be opened up in the Stillsands and you’ll have a much clearer picture of everything that’s around.
