Five official trailers, all on the Steam store page, in the order they were released.
| Trailer | What it is |
|---|---|
| Official Announcement Trailer | The first reveal |
| Official Demo Launch Trailer | Marked the free Steam demo, October 2025 |
| Official Release Date Trailer | Dated the game to 13 August 2026 |
| Official Release Trailer | Launch day |
| 公式リリーストレーラー | The Japanese-language release trailer |
The Japanese one is the same release trailer with Japanese narration and text, not different footage.
All five play on the Steam store page, which is the only place we can point you to and know the file is the official one.
There is no "secret teaser trailer"
This is worth stating plainly because Google suggests the phrase.
Type "servant of the lake secret" into a search box and it will offer you secret teaser trailer. Rusty Lake's Steam listing has five videos and none of them is called that, or is a teaser beyond the announcement trailer.
Search suggestions are generated from what people type, not from what exists. Somebody searched it, others saw the suggestion and searched it too, and now the phrase has traffic behind a thing that was never published. If a sixth video appears we will list it here.
There is a genuine secret in the game — a post-credits achievement — but it is content, not a video. That is documented on our sister site's "You've found him!" page, and it is a heavy spoiler.
Gameplay footage
The trailers are cut to sell rather than to show how the game plays. For actual gameplay, the free Lite build or Steam demo puts the opening in your hands at no cost, which is a better sample than any video.
Community playthroughs exist on YouTube and cover the full game, including the endings. We are not linking specific ones — they are unmarked for spoilers and change constantly.
