Grey Hack

Grey Hack is a massively multiplayer hacking simulator set across a vast network of procedurally generated computers. You play as a hacker with the freedom to explore, take on missions, attack systems and build a reputation. File Explorer, Terminal and Text Editor are available from the start, and you can install new utilities as your skills improve.

A persistent world

The online world is shared by all players and stays active 24/7, even when you leave the game. Changes you make to computers can be seen by players who connect to them after you log off. Your progress is saved, but your actions can have consequences.

Plan your attacks

Networks differ in their configuration, size and security, and the dynamic exploit system makes each network and computer a different challenge. You can study targets, use social engineering, scan for security oversights that could let you open a backdoor, and try different exploits. You also need to cover your tracks when an attack is complete.

The Terminal is central to carrying out attacks and uses commands based on real UNIX commands. Commands and exploits are written in the game's scripting language, so you can modify existing commands, create new ones and develop your own exploits if the ones available in the world do not meet your needs.

Open-ended play

You can progress at your own pace. Publish websites to share your creations, form guilds and organize attacks against other players, or complete missions for money and reputation. You can also explore on your own to find hidden special missions and other secrets.

Multiplayer and solo play

Grey Hack is designed for multiplayer, where players share an always-online world. It also has a single-player mode, in which the world is created on your computer. In single-player, the world stops when you leave and resumes when you return.
