Backrooms Lost Runners Early Access

Compare Steam page

Backrooms Lost Runners is a co-op survival horror with team play, voice-reactive AI, and immersive puzzles. This isn’t a “walking simulator”: explore liminal spaces, outsmart entities, and remember—even a whisper can give you away.

Posts announcing an update, tagged as patch notes or not

Last 90 days · as of 08:41 UTC

How this is measured

Posts in a game's official Steam news feed that announce an update: tagged as patch notes by the developer, or plainly about a patch or a released update.

News checked every 12 hours. Observed since 22 Oct 2026.

An announcement is not a build. Developers can ship updates without a post, or post about several updates at once.
Untagged posts are recognised from their words, so a few updates are missed and a few other posts may be counted. Tagged posts are marked Patch notes on the Updates tab; recognised ones are marked Update.
Older posts are being read back through each game's history, most played games first, so months before October 2026 fill in over the coming days.
