About Unpossess: Exorcism Simulator

Unpossess: Exorcism Simulator puts players in early‑1900s investigations where they act as exorcists confronting demonic possession. The game blends action, adventure and simulation while drawing on classic supernatural film motifs.

Cases can be tackled solo or with up to three teammates online. Each case requires cleansing the area, gathering evidence and performing a ritual, all while watching personal health and sanity meters.

01 / THE GUIDE

Co‑op Play

The title supports one to four players working together online, each assuming the role of an exorcist. Players share investigation duties and ritual responsibilities during a case.

Co‑op sessions rely on player coordination; there is no AI‑controlled teammate replacement, so communication is needed to balance cleansing, evidence collection and ritual preparation.

  • Discuss role division before each case to avoid duplicated effort.
  • Use voice chat or quick messages to sync timing during rituals.

02 / THE GUIDE

Core Exorcism Objectives

Players must cleanse the afflicted area, capture evidence, and conduct an exorcism ritual to free the possessed individual. These steps form the primary loop for each case.

Health and sanity meters decline as encounters intensify; keeping both meters above critical levels is required to complete the ritual successfully.

  • Prioritise cleansing before evidence collection to reduce immediate danger.
  • Watch sanity closely; pause when possible to allow recovery.

Progression and Customisation

Experience earned from cases unlocks new abilities and cosmetic options, allowing players to expand their exorcist toolkit as they advance.

Cosmetic unlocks provide visual variety for the exorcist, while abilities add new actions that can be employed in future cases.

  • Experiment with different abilities to discover which suit your playstyle.
  • Save cosmetics for milestones if you enjoy visual tracking of progress.

04 / THE GUIDE

Haunted Object Collection

Each player maintains a personal collection of haunted objects, displayed in the pre‑case lobby. The collection records items encountered in previous cases.

The objects are presented as decorative items; they do not alter gameplay mechanics but can be arranged to reflect personal taste.

  • Group objects by theme for quick visual reference.
  • Use the lobby display to discuss past encounters with teammates.

05 / THE GUIDE

Dynamic Demonic AI

Possession cases feature dynamically generated demonic AI, ensuring each encounter feels distinct. The AI controls the behavior of possessed entities and environmental hazards.

Because AI patterns vary, players must adapt their tactics for each case rather than relying on a single fixed approach.

  • Observe AI behavior early in a case to adjust your approach.
  • Keep a flexible load‑out to respond to unexpected actions.
