Cult of Four
Gather up to four plague doctors. Enter together—or face the darkness alone.

Four souls. One dying light.
Descend beneath the old world and finish the ritual before the plague finishes you.MORS CERTA,
HORA INCERTA
The bells have stopped. The streets are empty. Beneath the city, something ancient has begun to breathe.
Devil of the Plague is a 1–4 player co-op psychological horror experience set in a world of cursed castles, suffocating dungeons and forbidden ritual grounds. You are the last plague doctors still willing to enter.
Cooperation is not a feature. It is your final defense. Every rite demands a role; every mistake gives the darkness a new way in.
Gather up to four plague doctors. Enter together—or face the darkness alone.
Asag has woken. Its breath corrupts every chamber and everything it touches.
Carry the relics, speak in order and cleanse lands poisoned by forbidden magic.
Light is finite. Courage and solidarity are the only defenses left against the dark.
Older than scripture. Patient as stone. The Sumerian demon Asag has woken, and every shadow now carries its fever.
