MORS CERTA,
HORA INCERTA

A sickness
older than mercy.

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.

Doctrine / The final defense

Four steps into darkness.

Cooperation is not a feature. It is your final defense. Every rite demands a role; every mistake gives the darkness a new way in.

01 / CONVENE

Cult of Four

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

02 / AWAKEN

The Ancient Evil

Asag has woken. Its breath corrupts every chamber and everything it touches.

03 / PURIFY

Dark Rituals

Carry the relics, speak in order and cleanse lands poisoned by forbidden magic.

04 / ENDURE

Survival

Light is finite. Courage and solidarity are the only defenses left against the dark.

02 The ancient evil

Its breath
corrupts all.

Older than scripture. Patient as stone. The Sumerian demon Asag has woken, and every shadow now carries its fever.
