Steam Achievements Guide

Achievement Structure in HILLS

Steam lists roughly 25 achievements for app ID 2859100. They are not an “Event Witnessed I–XX” series — that naming was a wiki error and has been removed. Real trophies include training dummy Lv.4, Villain Breaker (Day 5 Albert), United We Cut Silver (Dune), Night of Atonement, Narrow Escape, tentacle and mastermind feats, Cosmic-Level Delicious, Legend of Gadola, Cherish Chastity, plus ED.1 through ED.5.

Full names and unlock notes live on All Achievements. Ending requirements sit on All Endings. If Steam desyncs, use the Heart Crystal in the Memory Room (v1.0.8+).

Categories Overview

• Combat & dungeon feats — Dummy Lv.4, Goblin Slayer, Dune, Albert (hideout / Safehouse), Guard Captain, slave trader, tentacle boss, Incarnation of Calamity.
• Side systems — Casino goddess gamble, escape club without light orb, painter body-model job, Phantasmal Corridor, Reckless sigil, Charvel’s ultimate dish.
• Ending trophies — ED.1–ED.5 individually, plus Legend of Gadola (boss set + ED.1 in one run) and Cherish Chastity (clean ED.1).

Achievements sync via Steam. Offline play may delay pops until reconnect; gallery progress still saves locally.

Recommended Unlock Order

1. Legend / ED.1 chart run — Follow Optimal Chart for most boss trophies and ED.1.
2. Money split — Repeat ED.1 prep with spending for ED.2; skip Reda for ED.4; hideout-intact branch for ED.5.
3. Specials — Goblin Slayer and Cherish Chastity on dedicated saves.
4. Cleanup — Use Missables and Memory Room recovery tools.

Time Management and Achievements

The campaign is only nine days. Boss and ending trophies compete for the same half-day slots as side content. Do not plan “after Day 12” hunts — that calendar does not exist. Budget with Action Points and branch before Day 5 if you need both Villain Breaker and ED.5.

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.
