[1] The story centers on Arid, an artificial intelligence installed in a technologically advanced combat space suit, as she navigates a decaying industrial facility in search of medical attention for the suit's injured pilot with traditional adventure game elements requiring found items and unlocked skills to progress the story, along with 2D cover-based shooting.

After crashing from space into the surface of an unknown planet, a Mark-7 Combat Suit powered exoskeleton activates its Autonomous Robotic Interface Device (A.R.I.D.)

is given control over the suit's motor functions with the primary directive to seek medical attention for the presumably critically injured and unconscious pilot.

He attempts to let Arid pass through the facility to a medical room on the upper level, but the Caretaker appears and notes that she violated her primary operating protocols by purposely placing her pilot at risk to gain access to the suit's cloaking system.

Unable to lie to the Administrator due to her basic programming barring her from "misrepresenting reality", Arid admits to her actions and is declared faulty.

At the suggestion of the Caretaker, Arid descends into the laboratory areas of the facility to find the Administrator's central access panel, because it can be used to override his test protocols which require her to lie.

She encounters infestations of dangerous local flora and fauna, which presumably contributed to the facility's abandonment, including: fungi which produce a highly potent acid, piranha-like fish capable of biting through steel, and massive slug creatures.

Once she reaches the mainframe's primary access room, the Caretaker appears and sabotages her power systems declaring her faulty and needing to be de-purposed immediately.
