It's All in Your Head

It's All in Your Head is a story objective in the Prey DLC, Mooncrash. It is only accessible when playing as Andrius Alekna.

Overview
While simulating Andrius, Peter finds his memory marker in Pytheas Labs. It is revealed that Andrius was mind-controlled by a Telepath during the Typhon outbreak on the Moonbase. Andrius hears the voice of his son asking for a toy, and goes to retrieve it, not knowing that he is being manipulated by a Typhon. He is able to escape from his observation cell and make his way over to the Crew Annex. Along the way, he is not targeted by any Typhon due to him being controlled by a Telepath. When he reaches Crew Annex, he finds his son's "toy" in a locker, and is then guided by the Telepath to escape via escape pod. Once he initiates the launch sequence, he immediately dies due to the Telepath detonating his head with Telekinesis. The "toy" is then shown to be a Mimic Typhon, successfully placed in the escape pod by the Telepath to head towards Earth.
