Rain98 Demo AppID 3738760 currently has six Steam Achievements. They belong to the free Demo, not the unreleased Rain98 base game at AppID 3498720. Steam’s public records expose six internal identifiers; two entries are reported as hidden, so a complete official English display-name and unlock-condition list is not publicly readable without revealing or guessing protected details.
Play the Demo naturally first. Several identifiers point toward story completion or alternate outcomes, but an internal key is not an official condition and should not be rewritten into a guaranteed step.

ACH_FIRST_LAUNCHACH_GAME_OVER_INPUT_NAMEACH_DEMO_CLEARACH_GAME_OVER_ROOMACH_MURBY_CHANGEACH_METEOR_RAIN_CLEARThese identifiers come from Steam’s public global-achievement endpoint as checked on October 18, 2026. They are included so you can distinguish six real entries from fabricated checklist items. They are not substitutes for localized names, descriptions, hidden flags, or exact triggers.
Unlock achievements on the correct product
Open the Steam library entry named Rain98 Demo and verify that its store URL uses AppID 3738760. Launch it while the Steam client is online. Let Steam finish any first-time setup, then reach the main game rather than closing from a configuration prompt.
For story-related progress, use ordinary saves and complete scenes through the Demo’s available first half of Chapter 2. Do not skip to the end with an event-build save. The public Demo’s own flags are what Steam can evaluate.
For alternate outcomes, make a normal save before a meaningful branch when the game permits it, finish one route, and then return through the game’s interface. Avoid repeatedly closing the process during a result scene; an achievement can be awarded after the game records the outcome.
See hidden and visible progress safely
The library’s achievement panel and Steam overlay are the authoritative view for your account. A hidden achievement can omit its description until earned. That design is not a missing translation or a broken page. If you want a spoiler-light run, leave hidden entries undisclosed and finish the Demo once before investigating alternatives.
Global completion percentages change as more people play. They can confirm that an entry is unlocking for some players, but they cannot prove the exact condition. A low percentage may reflect story length, an alternate outcome, a hidden task, or the Demo’s recent release.
Do not use Steam Achievement Manager or a save from another account as a diagnostic step. Those tools can mark account records without proving the game state works, and they make later troubleshooting ambiguous.
Fix an achievement that did not pop
First launch is missing
Confirm Steam is online, start AppID 3738760 from the library, and reach the Demo's opening. Close normally so Steam can synchronize.
A completion entry is missing
Load the last ordinary checkpoint, replay the final available sequence, and remain in game through its result and end-state presentation.
Overlay never appears
Check Steam's per-game overlay setting, close conflicting overlays, and relaunch both Steam and the Demo before replaying a short trigger.
You played offline
Reconnect Steam before loading the relevant save. Replay the smallest normal scene that leads to the result; do not assume every offline trigger retroactively syncs.
A hidden entry stays hidden
That is expected until Steam reveals it. Finish the story and documented activities before treating the concealment as a technical fault.
After a retry, open the Demo’s achievement panel and allow a few moments for Steam Cloud and community data to refresh. Capture the time, current chapter, and internal identifier if you report a reproducible issue. Do not publish a hidden story outcome in a title without a spoiler warning.
Keep Demo and base-game achievements separate
AppID 3498720 can have a different achievement set at launch. Similar names would not make the records transferable. Steam tracks each AppID independently, and no developer statement promises that Demo achievements will auto-award in the retail game.
A future Demo update that adds the rest of Chapter 2 could change descriptions, expose another trigger, or leave the current six untouched. Recheck the Demo’s library panel after that update rather than treating this snapshot as the final retail list.
For now, the reliable completion route is to launch through Steam, play the current Demo to its intended boundary, explore ordinary alternate outcomes with normal saves, and let hidden entries remain hidden until earned. That protects both your account state and the story.
