Human Farm Investigation Game Systems Reference
Mechanics behind investigation, items, cheats, achievements, and patching.
What belongs in systems
The systems hub documents rules engines in Human Farm : Investigation : — meters, inventories, cheat menus, Steam achievements, and the official restore patch pipeline. Story order lives in Walkthrough; player how-tos live in Guides. Use this section when you need precise mechanical vocabulary.
Game context: Steam app 3953160, とっくり海月 / 072 Project, August 7, 2026 launch, thirty-four story events, five or more endings, Day 1 demo.

Cross-links
Systems touch every hub:
- City Quests feed investigation meters
- How to Get Endings explains flag vs gallery
- Patch Install Helper operationalizes Official Patch steps
- Ending Tracker tracks flag outcomes, not cheat replays
Demo limitations
Demo Day 1 exposes subset systems — no full achievement list, limited gallery, no patch targeting demo depot. See Demo Day 1.
Patch-first troubleshooting
When mechanics “feel wrong” on Steam, verify patch state before re-reading mechanics pages — censorship and restored scenes change gallery expectations.

Systems are the rulebook — master them when story advice alone does not explain a silent fail.
Systems glossary quick lookup
| Term | Meaning |
|---|---|
| Raid-ready | Investigation meter satisfies Tsubaki raid prompt |
| Cover | Iori’s believability as farm staff |
| Gallery flag | Story variable set when scene plays legitimately |
| Unlocker | Menu tool replaying scenes without setting all flags |
| Restore patch | Publisher asset swap for Steam-cut visuals |
Use this glossary when reading Walkthrough checklists — the same words appear across pages intentionally.
When to read systems mid-play
You do not need systems mastery on Hour one. Touch Investigation Mechanics when handlers warn about missing evidence; touch Items when inventory feels full; touch Cheats only after first ending; touch Official Patch when gallery counts disagree with community lists after legitimate play.
Closing systems hub note
Mechanics pages assume full-game flags. Demo saves inherit suspicion rules but omit city and cafe systems — see Demo Day 1 before applying patch or cheat guidance here.
