No. It is an investigation-driven first-person mystery. You explore a five-floor office complex, read documents, news, and coworkers' emails, and piece the story together through observation rather than fighting.
What changed in version 1.1?
No detailed changelog was provided with this release, so version 1.1 is the reference point when comparing builds. The page shows the build as online with a last-updated date of August 31, 2025, and you can request a newer update through the site if you need one.
My antivirus flagged the game. Is it safe?
Treat any warning as something to investigate. The download source alone cannot confirm a file is safe, so review the detection details, keep your security software enabled, and only restore the file if you have verified it is a false positive. If you are unsure, leave it quarantined.
