GHOST OS: Phone Mystery

You found a stranger's phone. The battery is dying. Somewhere in its messages, photos, and hidden files is the truth about what happened to its owner — and a security system called WARDEN is trying to erase it before you can.

GHOST OS is a narrative deduction game disguised as a fake phone operating system. Every run generates a brand-new phone — a new owner, a new cast of contacts, new clues, and a new truth — so no two mysteries are the same. Crack the passcode, dig through the apps, weigh the evidence, and commit to what really happened before the screen goes dark.

▓ HOW TO PLAY


Unlock the phone using a clue hidden on the lock screen.
Explore Messages, Gallery, Notes, Weather, Music and Calendar for evidence.
Crack the secured apps — Mail, Banking, the Vault — and recover deleted files.
Every action costs battery. Curiosity vs. survival: choose what's worth it.
When you're ready, answer the case: Who, What, and Why. Get it right and the true ending unlocks. Get it wrong and you'll see exactly what you missed.
