How to unlock the Aided Kotallo achievement in Horizon Forbidden West - Definitive Guide

The What Was Lost questline starts in your base if done during the story, or in The Memorial Grove after the story. Call Kotallo at the campfire before entering the Zenith Research Lab. Follow the quest markers to the storage room. Once there, head to the back right corner of the room and use the access point.

After defeating the specters, follow the waypoints through a vent in the wall to an office where you can climb through a vent on the ceiling. The components are in the next room after leaving the vent. Meet back up with Kotallo to wrap up the research lab.

Later you can talk to Kotallo again at the base (during story) or The Memorial Grove (after the story). Meet him at another campfire before going on a hunt for a Scorcher. Take out the Scorcher to complete the quest and unlock the trophy.

At a certain point in the story, after you’ve got the subordinate function, Aether, Kotallo will ask for your assistance. To initiate this quest, you’ll have to trek back to The Base and speak to him, and then start and finish the quest, What Was Lost. This level 30 quest is a multi-part quest that has you heading back to a previous mission location with a different objective. After you finish that Kotallo will ask for some time. When that time has passed, he’ll get in touch with you to go and test what you discovered in the wilds. When you’ve tested the new equipment with Kotallo, the mission is complete and only then will the trophy pop.
