Plan your next Project Unknown session

Our independent guide breaks down Project Unknown’s core systems so you can approach each haunted job with confidence. By focusing on investigation, lighting, miasma, abilities, and tools, you’ll learn how to allocate resources, sync with teammates, and keep the darkness at bay.

01 / THE GUIDE

Journal Mastery

After each ghost encounter, write a concise note of its pattern. Compare notes with a partner to see how shared information improves route planning and survival.

  • Note ghost behavior immediately after spotting them.
  • Review teammates’ entries to fill gaps in your knowledge.

02 / THE GUIDE

Light Allocation Drill

Limit yourself to two active lights and navigate a room. Observe how the restriction forces you to choose safer paths and manage the breaker risk.

  • Plan routes that use the minimum necessary lights.
  • Coordinate lighting with teammates to stay within the limit.

03 / THE GUIDE

Miasma Timing Test

Identify the first visible miasma sign, then activate the Ritual Bell immediately. Track how early cleansing influences overall mission success.

  • Prioritize miasma hotspots early in the mission.
  • Use the Ritual Bell when miasma density is highest.

04 / THE GUIDE

Ability Synergy Session

Pair each character’s unique skill with a specific tool—e.g., Eirene’s tarot cards with the Curse Sensor—and note any changes in ghost interaction.

  • Assign each teammate a role that fits their unique ability.
  • Communicate cooldowns so abilities can be timed together.

05 / THE GUIDE

Tool Familiarization Run

Equip each specialized device in a low‑risk area. Record its effect on detection range and exorcism speed to build a personal reference guide.

  • Carry a mix of detection and cleansing tools for flexibility.
  • Test each device in a safe area before entering high‑risk zones.
