After releasing an unknown creature kept in sleep by the base, he has various visions of his mother and their past. At the bottom of the facility he finds the meeting room, seeing that they plan to create a moon colony named Eden. He investigates the depths of the complex, finding that the Filth has breached the base he also discovers blackmail Orochi had against the crew and cloning technology, calling into question the crew’s identities. Shane discovers evidence of the Filth’s creation and Orochi’s knowledge on the abrupt disappearance of his mother, as well as a facility of androids in storage.

While Josephine Wilcox and Declan search the remains of the Cyrano, Shane finds a hidden elevator in the server room leading to a hidden facility beneath the base known only to Orochi and Volkova. He is attacked by scientist Inna Volkova, who has merged with the tree, and he puts her out of her misery. After being forced to run to the greenhouse from outside without a helmet, a weakened Shane manages to poison the water supply and kill the tree by destroying its roots. Returning to the main base, he finds that the Filth has overrun it and killed Lukas, leading him to find Lukas’ research on a venom that could kill the Filth tree. Making contact with the others, Shane flees the outpost as dark figures resembling astronauts begin to follow him. Inside the outpost he finds evidence of Declan’s dropping mental state and sees figures outside as he repairs and boosts the comms. He ascends the formation leading to the tower, when he sees the supply ship the Cyrano crash into the planet. He discovers a book connected to a shrine, and he awakens in his rover, the ordeal revealed to be a dream. After solving puzzles in a location resembling the basement of his home. He powers various orbs using a strange birthmark on his hand, and makes his way to a cave where he sees The Witch, a strange disheveled old woman that haunts the dreams of the crew, spouting unusual and cryptic words, especially regarding Mars and the Moons Phobos and Deimos.

When he exits his rover, however, Shane finds a cave materialized out of nowhere from behind him and he enters finding areas within the cave looking like they were torn out of his family house on Earth. After fleeing the greenhouse, he heads towards the comms tower station, where his friend and partner Declan Delapore is stationed. After dumping the water, the biomass transforms into a giant, mutated tree, and Shane is attacked by a semi-humanoid creature made from the biomass.

Upon doing so, however, he discovers the work of botanist and biologist Inna Volkova and Lukas VanBuren, an experimental, plant-like biomass he also hears and sees an obscured figure around the greenhouse. While the crew are out at various stations with other duties, Shane leaves the main base and realigns the solar panels, then heads back to the greenhouse, where he resets the water system. Engineer Shane Newehart awakens on the currently concealed Mars base created by the Orochi corporation.
