What the developers have to say:

Why Early Access?

“In a game of this nature community feedback is essential for fine-tuning and balancing all its aspects, especially in multiplayer mode where players share a world that reacts to their actions.”

Approximately how long will this game be in Early Access?

“Being the only developer and given the scale of the game, it is difficult to predict a date since there are several factors involved such as community feedback. You can check the roadmap to see the current state of development of the game.”

How is the full version planned to differ from the Early Access version?

“Currently all the main game mechanics are implemented. Therefore the final version will be a more polished release in terms of stability, bug fixes, and quality-of-life improvements, as well as an increased quantity and variety of available missions.”

What is the current state of the Early Access version?

“Grey Hack is in the Beta phase, which means that all the main mechanics and most of the secondary ones have already been implemented. However you may still encounter some bugs or mechanics that require balancing adjustments.

Please note that due to ongoing development, single-player and multiplayer saves may be reset in future updates.”

Will the game be priced differently during and after Early Access?

“The price will gradually increase as new contents and features are added.”

How are you planning on involving the Community in your development process?

“Steam forums and Discord will be the main sites to give feedback, get to know news, discuss aspects of development, etc.

I follow the forums very closely, as I am very interested in receiving feedback from the community and working together.”

About This Game

Grey Hack is a massively multiplayer hacking simulator. Work with other hackers or target their systems, using tools you can inspect, modify, and create yourself.

Make your mark on a shared world

The world keeps running when you log off. Your changes to shared systems can affect other players, and their actions can change what you find when you return. Share discoveries, coordinate attacks, or defend your computers from other hackers.

Form a guild, pool funds, and compete with rival guilds for control of companies. Upgrade your hardware and rent servers to support your next project.

Find a way in



Scan services, study your target, and look for an opening. Exploit vulnerable software, escalate your privileges, or use social engineering to trick an employee into opening a connection.

Firewalls, permissions, network layouts, and software versions shape your approach. Administrators can detect intrusions and trace connections, so plan ahead and cover your tracks.

For a deeper challenge, investigate rumors of undiscovered vulnerabilities, identify errors in code, and develop exploits or patches.

Rewrite any command

Every terminal command is a GreyScript program, with source code you can open, read, and modify in the game's code editor. Learn how a utility works, change its behavior, or use it as a starting point for something new. Even the shell that interprets your commands is written in GreyScript, and you can create your own.



Use the same scripting language to create commands, automate tasks, write exploits, and share your tools with other hackers. Run what you build in the Unix-style terminal and put it to work across the network.

Follow the evidence

Take contracts from hackshops and the police to earn money and reputation. Trace evidence through files, emails, and connected networks as you investigate fraud, extortion, and corporate espionage.

Explore further to discover hidden jobs, access surveillance cameras, and uncover evidence of crimes. Report what you find or use it for blackmail. Your actions affect your karma and the opportunities that open up.

Give other hackers something to discover

Host an in-game website to share your work, or create Capture the Flag challenges for other players. Configure the network, design the challenge, and script the conditions for success.

Explore on your own terms

Single player offers a separate local world that pauses when you leave and resumes when you return. Tutorials and an in-game manual introduce the tools. Experiment, learn how they work together, and choose your next target.

Roadmap

Grey Hack is currently in beta (version 0.9). The development roadmap is available in the game's Steam forum. I welcome suggestions from the community, so if there's a feature you'd like to see, feel free to share your ideas on Steam or Discord.
