MysteryOS is a puzzle-survival game where every level drops you into a completely unknown operating system. Nothing works the way you expect. The language is alien. The UI is unfamiliar. Every wrong action has real consequences. Your job: figure out how this system works, decipher its constructed language, solve environmental puzzles, and survive long enough to escape. Level 1: AXIOM is completely free. Boot up and see if you can handle it. Available today at 5:30PM AEST on Windows, macOS, and Linux.
