Below is a walkthrough for the Level 20 Tallneck: The Stillsands quest in Horizon Forbidden West. To obtain this quest, approach the Tallneck south of Camp Nowhere.
Examine the Machine Carcass
Examine the machine near the Campfire.
Investigate the Camp
Examine the corpses near the campfire, the Tallneck components near the tarp and the ballista.
Weigh Down the Tallneck
Use the ballista to shoot an anchor on the Tallneck.
Find More Ballistas
Head east of the campfire to find another ballista on a wooden platform along the ridge. Again, use it to shoot an anchor on the Tallneck. The last ballista can be found southwest of the fire. Use it to shoot the third and final anchor in the Tallneck. Near this ballista, look on the table to find the Good Day Gone Bad Datapoint.
