Room 404 OST is now available for free!

Steam version includes 24 tracks from both the game’s trailers and in-game music. Depending on the atmosphere of each scene, the OST explores a variety of styles, including electronic music, emo rock, glitch music, and more.

The OST is also available on Bilibili, Youtube, and other platforms. The video versions include cover art and music visualizers,feel free to check them out if you're interested (you may even discover a few story-related clues…?)

We're still working on updates and improvements to the game.

The CG Gallery is currently in development, and we hope to share it with you soon~

If you run into anything that feels off, just drop a note in the Steam discussions.

We’ll jump on it and push out improvements as fast as we can.
