A sentient alien organism has escaped its cage and now freely roams a government facility. Silence has engulfed the city as a toxic and unidentified cloud was released from black oily stones. Witness and investigate a dire situation that appears to escalate by the hour.
Oppcium is a survival horror game where you play as Melissa Winston as she investigates a government facility. Stealth is a core mechanic, together with exploration, puzzle-solving, and resource management. Chapter 1:

Explore and investigate the vast area that covers the perimeter of the futuristic facility. Scour for resources and fabricate tools out of blueprints that will further aid you with the investigation.

Work together with Sabine, a cybernetic organism tasked to aid you in uncovering the crisis that left the whole facility silent.

Delve deep into the corridors of S02/47-B and avoid the ever-expanding threat that lurks around the corners.

Get immersed in a True FPS experience and try to make the best out of an unpredictable situation.

DISCLAIMER: - Very difficult game. - Involves backtracking through a relatively open world. - 3-6 hours of gameplay per chapter. (Chapter 1/3) - No hand-holding.
