Plan your next The Posthumous Investigation session

Our independent guide helps you deepen your investigative approach without altering the game's built‑in systems. By examining each documented element, you can refine how you gather and interpret information, making each loop more productive.

01 / THE GUIDE

Schedule Mapping

Create a separate sheet for each character, listing their known locations per hour. Compare sheets to identify overlapping times that may reveal hidden interactions.

  • Record observed schedules before the loop resets to avoid losing details.
  • Focus on contradictions first, as they often reveal the killer’s manipulation.

02 / THE GUIDE

Contradiction Spotting

After each loop, list statements that conflict with observed schedules. Prioritize these contradictions, as they often point toward deceptive behavior.

  • Create a timeline chart for each character to visualize overlaps.
  • Compare scheduled activities with actual sightings to spot inconsistencies.

03 / THE GUIDE

Evidence Clustering

Group collected clues by type—physical items, testimonies, timestamps—and place them together on the Thinking Board to see larger patterns.

  • Group evidence by location to see spatial patterns.
  • Link statements that reference the same time slot for clearer contradictions.

04 / THE GUIDE

Accusation Testing

Draft multiple accusations based on different logical paths, then cross‑check each against the full timeline to see which holds under all conditions.

  • Observe background details for subtle hints about character habits.
  • Appreciate the artistic style to better understand the story’s tone.

05 / THE GUIDE

Platform Utilization

Enable Steam Cloud before starting, then experiment with the supported controllers to discover which input method best supports your board organization.

  • Steam Cloud is among the listed Steam features, which may be worth enabling in your Steam settings.
  • Try the supported controllers to see which input feels more natural for the Thinking Board.
