PHOBOS description

Phobos is a social deduction co-op horror game that drops you onto the moon’s wrecked frontier: a derelict space asylum carved into Phobos’ hollowed hull. A mega corporation used this facility to "rehabilitate" intergalactic horrors and criminals. The project failed in chilling fashion, and now a crew of employees must navigate discarded laboratories, flickering lights, and echoing corridors to complete essential tasks and repair the facility—without becoming the next casualty.

In this tense mission, survival depends on smart teamwork and careful trust. Most tasks are cooperative by design; some are straightforward, others demand simultaneous actions, precise timing, and clear communication. The catch: a few crew members are secretly Infected, their minds warped by something Eldritch and ancient. They will sabotage tasks, mislead their teammates, and strike when suspicion is low. Good players must maintain a wary eye, weighing every confession, every alliance, and every shadow.

As you press onward, the truth behind the asylum’s experiments surfaces. Years of psychological and biological testing have left monstrous entities lurking in the shadows. These intelligent beings hunt with a grim, calculated cruelty and appear to share a sinister plan. They are not merely predators; they are an ominous backdrop that raises the stakes for every crew interaction and every repair order.

Phobos challenges you to balance cooperation and distrust, speed and accuracy, risk and caution. The clock tightens as days pass, and the asylum’s systems degrade. Repair the hull, restore life support, and unlock access to sealed sections, all while navigating compromised loyalties and underground horrors that seem to anticipate your every move. In this moonlit maze, your best chance to survive hinges on deciphering who to trust before the infected strike, before the horrors converge, and before there is nothing left to save.

  • Cooperative tasks that require teamwork to fix the facility
  • Hidden Infected players sabotaging from within
  • Smart social deduction where trust is your most valuable resource
  • Ambitious, intelligent horrors hunting the crew
  • Escalating danger as the clock runs out
