Steam Achievements Guide

Achievement Structure in HILLS

Steam lists 25 achievements for app ID 2859100. PantyParrot expanded the Event Witnessed series from the eleven achievements in The Adventures of MICOCO to twenty optional scene trophies here, reflecting Gadola's larger district map and companion web. The remaining five achievements cover story completion, the true ending, a major bad ending, full ending gallery registration, and master completion.

Most event achievements unlock automatically when you view their associated scene during normal exploration. The difficulty is finding the scene before the day or district gate closes—not performing a obscure input combo. Cross-reference How to Find for clue locations and Hidden Locations for off-map triggers.

Categories Overview

• Event Witnessed I–XX (20) — Optional CG or story events tied to districts, companions, or risk checks. Listed in full on All Achievements.
• Story Progression (3) — The Adventures of HILLS (complete main quest), Light in the Shadows (true ending), The Clock Runs Out (timer bad ending).
• Completion (2) — Every Stone Turned (all endings registered), Chronicler of Gadola (100% gallery / all achievements).

Achievements sync via Steam Cloud. Playing offline may delay pop-ups until reconnect; progress still saves locally in the gallery.

Recommended Unlock Order

1. First playthrough — Focus on story; you will naturally hit Events I–VIII and earn The Adventures of HILLS.
2. True-ending run — Route for Light in the Shadows using the Requirements Checklist; picks up most remaining events IX–XVII.
3. Cleanup run — Use Missables for XVIII–XX and bad-ending trophies.
4. Gallery sweep — Trigger Every Stone Turned after viewing all endings on All Endings.
5. Final — Chronicler of Gadola pops when the other 24 are unlocked.

Time Management and Achievements

Because HILLS is a calendar-driven RPG, achievements compete for the same Action Points as main-story beats. Chasing every event in one run risks timer failure or exposure bad endings. Budget using Action Points guidance: reserve two days in mid-game solely for optional events if you are achievement hunting.

Events XVII–XX are heavily gated behind Noble Quarter access and high companion loyalty. Attempt them after Day 12, not during the tutorial crunch.

Comparison to The Adventures of MICOCO

HILLS inherits PantyParrot's achievement DNA from the prequel: numbered optional events plus a capstone story trophy. MICOCO shipped with eleven achievements (ten event watches and one completion); HILLS scales to twenty-five because Gadola is larger, companion loyalty is deeper, and multiple endings each carry their own unlock.

Event Witnessed numbering is internal—Steam displays the Roman numerals, but the gallery uses event IDs that do not always match chronological discovery order. Event VII (Micoco) can trigger before Event III (Slums cellar) if you follow main story linearly. Completionists should track by our table, not by the order achievements pop.

Unlike MICOCO's single homecoming ending, HILLS splits story completion across The Adventures of HILLS, Light in the Shadows, and Every Stone Turned. Treat them as three layers: finish the game once, finish it optimally, then finish the gallery metadata.

Steam Cloud sync matters more here because a single playthrough spans more days and more save slots. If an achievement fails to register, verify integrity of local saves before replaying a twenty-hour route.

Steam Client and Tracking Tips

Achievement pop-ups can be delayed until scene transitions complete—wait for the black fade before force-quitting. If a trophy does not appear, open the Steam overlay achievement list and confirm the scene registered in-gallery first; some events award gallery before Steam sync.

Family Sharing copies inherit achievement progress separately—each Steam account needs its own witness run. Offline mode queues unlocks locally; reconnect before starting a new playthrough to avoid duplicate effort.

Speedrun categories on community boards often exclude achievement hunting, but Any% with Achievements is a growing category—routing uses our Unlock Order with minimal gift spending.

Profile and Showcase Recommendations

For Steam profile showcase, players often display Chronicler of Gadola or Light in the Shadows as capstones. Event Witnessed XX is rarer globally at launch and also works as a flex trophy. None are time-limited—take your time routing true ending before hunting rare stats.

Legend and Icon Notes

Steam achievement icons use Roman numerals for events and distinct crests for story trophies—useful when scanning a friend's profile for missing IDs without asking for spoilers. Chronicler icon only appears when 24/24 others are complete; if it is missing, compare Event Witnessed count first.
