About Grey Hack

✦ AI summary

Hack your way through a persistent online network of procedurally generated computers using real Unix commands and custom exploits you create yourself. Leave your mark on a living world shared by thousands of players where your actions have lasting consequences, or play solo at your own pace in a non-linear sandbox where you decide your own hacking destiny.

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.

A living persistent world


Explore the Grey Hack universe and forge your own reputation in a world shared by all players. When you leave the game, the online universe remains actively running 24/7.

This always active game session means that the changes you have made in any computer in the world can be seen by players who connect to them even if you are no longer online. Your progress will be saved, but your actions may have consequences.

Plan your attacks


Each network in the world has a totally different configuration, size and security, also using a dynamic and deep exploit system so that each network and computer poses a different challenge. Study your target; use social engineering, scan the system for administrator flaws that allow a backdoor to be opened, test different possible exploits, but above all, cover your tracks when you're done.

Create, modify, share


The terminal has a fundamental role, based on real UNIX commands; it is an indispensable tool for carrying out successful attacks.

Terminal commands and exploits have been built using the scripting language available in the game, this means that you can modify any existing command or create your own if you wish. In the same way you can create your own exploits if the ones that are already available in the world do not satisfy your needs.

Sandbox


Grey Hack offers a non-linear experience where you progress at your own pace. Publish web pages to share your creations, create guilds and organize attacks against other players, carry out commissioned missions to earn money and reputation, or explore the world on your own where special missions and other secrets are hidden.

Single Player Mode


Grey Hack is intended to be played in Multiplayer Mode, benefiting from the richer environment of an always-online universe, but the game also offers a single player mode for those so inclined. In Single Player mode, you play in a world created on your computer. Unlike Online Mode, when you exit the game in Single Player, the in-game universe stops, and progress resumes only upon your return.

Roadmap


Grey Hack is in the Alpha phase version 0.8. You can check the roadmap on the game's Steam forum. I am open for suggestions, if there is any feature you would like to see in the game, do not hesitate to let me know through the Steam forums or Discord.

I most definately recommend this game to anyone that loves computers. I know that it is just a game and the tools/exploits are not the same as the real ones but what you learn through this game is a deeper understanding of how systems are connected to accomplish the main goal. Also it helps you understand how code is used to communicate what you want done with which file, in which folder, on which device, via which network, and knowing the basic structure code uses to manipulate those files, folders, devices, and networks effectively. Once you are able to see all of these things clearly you can apply them to real world situations and have fun making money. Im far from a hacker so its possible that I dont know what the h@l! Im talking about. One thing for sure though, if you arent fluent in Linux, this game is a great way to get some practice and muscle memory formed.
