Horizon Forbidden West - Recovered Alva's Data Trophy Guide - Forbidden Legacy Quest - Alva's Quest

The Horizon Forbidden West trophy guide showing the Forbidden Legacy side quest needed for the Recovered Alva's Data trophy on PS4/PS5.

The questline starts in your base if done during the story, or in Legacy's Landfall after the story. Follow Alva to the nearby ruins, kill the Slitherfang, and search for a vent low on a wall. Kick the vent in, and search for the access point.

Then follow Alva toward Atbay Headquarters in the nearby jungle. Work your way through an adjacent ruin to find the entrance to Atbay HQ covered by some rubble. Clear the debris and ascend the tower. There are 2 locked doors. The door codes are 102023 and 402625. Finish reaching the top of the tower, watch the cutscene, and the trophy will unlock.
