100% Completion Guide
Full completion in HILLS means 25/25 Steam achievements, all gallery endings, every Event Witnessed scene, and critical key items logged. This guide orders the work across minimal playthroughs so you do not burn Action Points on dead-end repeats.
What Counts Toward 100%
- Steam achievements — All 25 listed on All Achievements.
- Ending gallery — Twelve unique ending IDs per All Endings.
- CG gallery — Main + optional scenes, including Event Witnessed I–XX.
- Key items journal — Story items in Key Items; deluxe artbook entries optional for gameplay 100%.
The in-game completion percentage weights gallery higher than achievements. You can hit 100% in-game with one achievement missing if Steam desynced—verify on the Steam client.
Optimal Three-Run Strategy
Run 1 — Story Foundation (8–12 hours)
Blind or light-guide first playthrough. Goals:
- Complete main quest → The Adventures of HILLS
- Natural Events I–VIII
- Learn combat and exposure systems via How to Play
- Finish with a good ending; save post-credits slot
Run 2 — True Route + Events IX–XIX (10–14 hours)
Start fresh with Requirements Checklist open.
- Light in the Shadows and Event XX
- Remaining district events and Noble Quarter scenes
- Max companion loyalty for pledge night
Run 3 — Cleanup + Bad Ends (4–6 hours)
Use curated saves from Save Points and Missables.
- The Clock Runs Out and other bad endings for Every Stone Turned
- Any single missed Event Witnessed trophy
- Chronicler of Gadola auto-unlocks when 24/24 others are done
Single-Run Perfection (Advanced)
Experienced PantyParrot players can combine Runs 1–2 by following the true-ending checklist from Day 1 and only deviating for missable events. Requirements:
- Zero wasted AP on repeatable grinds—see Action Points.
- Hit every district on its unlock day per Unlock Order.
- Never fail the Day 9 timer extension quest.
- Enter finale with exposure under 25% buffer.
Bad endings still need another file or pre-finale branch saves—plan Run 3 regardless unless you intentionally fail early.
100% Checklist by System
| System | Target | Wiki Page |
|---|---|---|
| Endings | 12/12 IDs | All Endings |
| Events | 20/20 witnessed | All Achievements |
| Companions | All recruited + max loyalty once | All Companions |
| Map | All districts + hidden areas | Map Hub |
| Items | All key items | Key Items |
| Combat | All boss scenes viewed | Boss Strategies |
Time Budget Estimate
Total for 100%: roughly 22–32 hours depending on puzzle difficulty and whether you read in-game text. Achievement cleanup after true ending is the fastest phase—avoid replaying the entire tutorial by keeping milestone saves.
Deluxe Edition Note
The Deluxe artbook DLC does not affect Steam achievement count. Collectors may want it for external artwork, but gameplay 100% is base-game only. Details on Deluxe Edition Items.
Hour-by-Hour Efficiency Tips
After your first playthrough, optimize with these time savers learned from early Steam community routing.
- Skip repeat battles — Once arena rank is secured, avoid random Slums encounters unless farming gold; they do not count toward achievements.
- Gift batching — Buy all companion gifts in one Market trip after Day 10 prices rise; loyalty events are time-gated, not gift-gated, after 80%.
- Save scumming for missables — Only reload for Events XIV and XIX if you are within the same day; cross-day misses need earlier slots from Save Points.
- Bad ending batching — Dedicate one evening to load Slot A (Day 1) and trigger timer and exposure failures back-to-back for two achievements in under an hour.
- Gallery audit — Before starting Run 3, open gallery silhouettes; cross-check against our table to avoid replaying entire districts for one missing Event Witnessed VI.
Total optimized time: experienced players report 18–22 hours for full completion versus 30+ for unguided blind runs.
What 100% Does Not Include
Clarify scope so you do not over-grind.
- Deluxe artbook pages — cosmetic DLC only.
- Every repeatable Market job outcome — no achievement tied.
- All combat S-rank clears — optional gallery flair, not Steam.
- Max gold hoard — economy achievement does not exist.
- Every dialogue permutation — only primary scene per event counts for Event Witnessed.
In-game gallery percentage may still show 100% when Steam shows 24/25 if one trophy desynced—verify both clients after each run.
Post-100% Goals
After Chronicler of Gadola pops, optional goals remain: S-rank all arena fights, max gold, every dialogue variant in gallery theater. None affect Steam—stop when you are satisfied. PantyParrot may add DLC later; this guide covers base June 2026 retail only.
Sharing Completion Proof
Screenshot Chronicler pop and gallery 100% for community threads—helpful for verifying guide accuracy across patches. Note your difficulty and run count when posting routes so newcomers can calibrate time investment.
Frequently Asked Questions
What is the last achievement I should earn?
Chronicler of Gadola is a meta trophy that unlocks after the other 24. Event XX and Every Stone Turned are usually the last substantive hurdles before it pops.
Does skipping H-scenes hurt 100%?
Most adult scenes are achievement-linked. You need to view each Event Witnessed scene at least once.
Can I use saves from Steam Cloud?
Yes, but label your own milestone slots locally. Cloud overwrites can erase branch saves if you play on multiple PCs.
What percentage is "good enough" before cleanup?
Finishing Run 2 with true ending plus 20/25 achievements is typical. Run 3 mops bad endings and straggler events—budget one afternoon, not another full playthrough.
Is platinum-style 100% worth it?
Twenty-five achievements is manageable for genre fans—no grind-heavy super-boss. Chronicler of Gadola is respect completion for a dense single-city RPG.
How do I verify I am truly at 100%?
Steam shows 25/25 achievements and Chronicler unlocked. In-game gallery should list all endings and events without silhouettes. Cross-check both—either can desync after crashes.
Is 100% required for story satisfaction?
No. True ending alone delivers narrative peak; achievements add completionist satisfaction and profile flair.
What if Chronicler does not pop at 24/24?
Restart Steam client and verify no duplicate Event Witnessed gaps in gallery. One desynced trophy may need replaying a single scene.
Does 100% include deluxe artbook?
No. Gameplay 100% is base game achievements and gallery only.
How many runs for 100% realistically?
Two to three for most players—one story, one true route, one cleanup afternoon for bad endings and stragglers.
