Human Farm Investigation How to Unlock Every Scene

Understanding the thirty-four event roster

Human Farm : Investigation : ships with thirty-four story events in the full Steam release (app 3953160). Each event belongs to the scene gallery and ties to specific characters, days, and prior choices. Events are not random drops — they require you to meet location, affection, investigation, and sometimes item conditions documented across character guides and the walkthrough hub.

This guide explains the system behind unlocks. For a tick-box list, pair it with the Scene Checklist tool and character pages such as Farm Cast and Police Allies.

Gallery vs story unlocks

The in-game gallery records scenes you have viewed during normal play. Replaying from the gallery does not retroactively set story flags unless the game clearly states otherwise. Two critical distinctions:

Gallery unlock — you watched the scene once under valid conditions. It appears for replay in the collection menu.

Story flag — internal variable used for endings, job performance, or later scenes. Replaying gallery entries may not restore missing flags if you loaded an old save.

The scene unlocker option mentioned in Cheats and Unlockers lets you bypass action minigames or view locked gallery entries in some configurations, but it does not unlock endings and may not set one-time flags. Use unlockers for replay convenience, not route completion.

General unlock rules

While each event has unique requirements, these patterns cover most of the roster:

Day and time windows. Evening scenes often expire if you are still in the city or farm wrong zone after a trigger hour. Enable run mode (Settings and Run Mode) and plan routes backwards from the event time.

Farm labor completion. Skipping assigned farm-shift or maintenance tasks frequently blocks Aina, Karen, or Boss-linked scenes even when dialogue flags are ready.

City quest completion. Many Maria, Rui, Alice, and Tsubaki scenes need topside quests from City Quests finished one or two days earlier.

Cover and suspicion. High suspicion can redirect scenes to failure variants or silence entire chains. See Investigation Mechanics.

Item delivery. Gifts and evidence items from Items must be in inventory before the trigger NPC spawns.

Prior scene dependency. Some events require an earlier event from the same character route — the Scene Checklist orders these dependencies.

Character route overview

Events cluster by cast. Use dedicated pages for nuance:

Cluster	Characters	Wiki page
Protagonist introspection	Iori	Iori
Police / handlers	Tsubaki, Maria, Rui	Police Allies
Farm residents	Aina, Karen, Boss	Farm Cast
City performer	Alice	Farm Cast

The Roster table lists ages (all twenty-plus) and first appearance days without spoiling every branch.

Step-by-step hunting method

1. Finish a blind first run if you dislike spoilers — you will naturally unlock forty to sixty percent of the gallery.
2. Start a structured second run with saves labeled by day in Beginner Tips format.
3. Open Scene Checklist and sort by missing entries.
4. Cross-reference Story Overview for day boundaries.
5. Verify patch status if Steam-cut content seems missing — Official Patch.
6. Use cheats only to retry action segments, not to skip flag setup — details in Cheats and Unlockers.

Common failure cases

“I was in the right room but nothing triggered.” Confirm facing direction, prior quest completion, and that you did not exhaust the time window by triggering a lower-priority scene first.

“Gallery shows unlocked but ending checklist incomplete.” Endings use separate flags — read How to Get Endings and True Ending Checklist.

“Unlocker added gallery entries but achievements did not pop.” Some achievements require legitimate first-time unlocks during story saves — see Achievements.

“Scene plays censored.” Default Steam cut may differ from patched content. Install the restore patch via Patch Install Helper before comparing to online lists.

Speed vs legitimacy

Speedrunners sometimes combine unlockers with save scumming. Legitimate completionists should disable cheats until NG+ or dedicated gallery hunting saves to keep achievement tracking honest.

If you only care about narrative closure, prioritize Ending Routes — not every gallery entry is mandatory for every ending, but true ending paths often expect most core scenes.

Maintenance after patches

072 Project may rebalance flag thresholds post-launch. When patches drop, re-run npm run verify on this wiki’s content pipeline and check update notes on Steam. Community spreadsheets should list patch version next to each event ID.

Unlocking every scene is a completionist goal, not a prerequisite for enjoying Iori’s story. Work methodically, label saves, and treat the unlocker as a replay tool — not a substitute for investigation work.
