Making New Memories

The "true"/secret ending, and one of three mutually-exclusive finishes - taking it locks out Return to the Colony and Cost of Lost Memories on that choice. You need Lily's progress bar at 100% (it fills from side quests plus the memory sticks and documents you collect - see Records Collector), then Take Adam's Hand at the final Selection of Species choice. Make a manual/cloud save right before the choice so you can reload straight after and grab Return to the Colony on the same run. Comes with a post-credits scene.
