## Description

An artefact long buried, a signal long silenced, both now in your hands. You shouldn't have either.

An artefact long buried, a signal long silenced, both now in your hands. You shouldn't have either.

The handheld was pulled from a wreckage no one will discuss. The previous owner was silenced for what they found. The OS is locked, the files are encrypted, and the signal hasn't stopped transmitting since the day it was sealed. Whatever they were piecing together, you're going to have to finish.

AXIOM/1, the free first chapter, is twelve missions deep into someone else's investigation. Read the threads they couldn't send. Crack the vault they couldn't open. Decrypt the manifest they were never meant to see. Trace the signal back to the bay it should never have left. Trigger what they were trying to trigger before the silence reached them.

No accounts. No ads. No telemetry. No cloud. No daily login streaks, no in-app currencies, no purchases required. Just the device, twelve missions, and the slow dawning of what Project ECHO actually was.

WHAT'S IN THE BOX  
12 missions across 12 alien apps and a hidden terminal
Banking, photos, calendar, files, messaging, star map, all of it living inside the device
Three hidden mini-games tucked in the corners (SERPAX, KETH WAR, KOOLAR)
45 to 60 minutes to complete the first chapter
Fully offline. No internet required.

Originally on Steam (PC / Mac), now redesigned for iPhone. Touch-tuned, vertical, calibrated for the screen in your pocket.

Future chapters arrive as paid expansions. The first is free forever.

PRIVACY  
Zero data leaves your device. No analytics, no SDKs, no account, no cloud sync. Game state is stored locally and only locally.
