In the 24th century, the remote planet B104-GS12 hides a dark secret. Once a military outpost, then a penal colony, the site â known as the Citadel â became a covert laboratory for illegal biotechnological experiments on human subjects.

When all communication with the Citadel suddenly goes silent, a military spaceship is sent to investigate. Before answers can be found, the ship is destroyed, and you crashâland on the hostile world as the sole survivor.

Stranded 12 lightâyears from Earth, with no hope of rescue, you are forced to enter the Citadelâs depths to complete your mission. To uncover the truth you must explore the mysterious halls, the remnants of forbidden experiments, and do whatâs necessary to ensure your survival.

Itâs you against the Citadel â and whatever horrors lurk within.
