About this game

Welcome to exorSYS
After unknowingly upgrading to a cursed operating system, you must follow a breadcrumb of previous victims in order to uncover the truth before you inevitably become a victim yourself. Solve puzzles, dig for secrets, hack computers, and use special programs to help advance from level to level.

Something is trying to keep you out. Use the included exorSYS Report Panel when connecting to hacking into another computer to report anything strange. Pay close attention to your environment for anything out of the ordinary. It can be something simple like a displaced or missing object. Sometimes it's far worse.
