Soon after Ryley Robinson’s return to Alterra, several research teams are sent to 4546B to catalog the species there and begin to uncover alien technology left by the Precursors.  During one research mission, you and your team are sent to explore the Lost River.  However, not far along into the expedition, your team is attacked by a Ghost Leviathan.  You manage to escape in a SeaMoth just before the Cyclops explodes, although it’s damaged by the blast.  Disoriented, you travel deeper into the depths of the Lost River, until you finally stop where we find you now.  You decide to get out and quickly construct a base for shelter, hoping to have a safe place to recuperate and decide what to do next.  However, moments after you finish the base’s construction, a River Prowler attacks, destroying your SeaMoth, and knocking your Habitat Builder into the brine…

This save file starts you in the Lost River Junction with a base and a small number of resources in a locker.  Your goal is to make it to the surface alive.  Once you reach the surface, the challenge is complete.  From there, you can complete the game as you normally would, if you wish.
