Space Edit 1: Added Fritz's image.
Project Survival's goal was to destroy PF's Alpha AI. Fritz resides on a cliff in Blood Gulch early on, then cloaks herself and her travel vehicle, following them wherever they go. She does not interact with them. Since, in PS's eyes, the Alpha is long since destroyed, she hangs around because she wants to, and keeps to the shadows. She tries to help the crew, in any way she can, to get back home.
