Grey Hack is a massively multiplayer hacking simulator game.
You're a hacker with full freedom to act as you wish on a vast network of procedurally generated computers. File Explorer, Terminal and Text Editor are some of the programs that will be available from the start of the game. As you improve your skills you will find new utilities that you may install and use. The terminal has a fundamental role, based on real UNIX commands; it is an indispensable tool for carrying out successful hacking operations.
