What the developers have to say:

Why Early Access?

“One of the main objectives is that the game takes place in a changing and lively world.
Although in this phase of development this world is working, it still does not have the level of depth and complexity that I have marked as objective and the feedback from the community can be very useful to finish developing this and other aspects of the game.”

Approximately how long will this game be in Early Access?

“I estimate that Grey Hack will be in Early Access for about 10 months.”

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

“The final version will feature a variety of procedurally generated missions.

It will also have plots and secrets hidden by the world that you will be able to discover and solve since the gameplay will not be limited only to the missions by contract.

The final version will also have a much more complex world and of course a greater variety of hacking programs and techniques.”

What is the current state of the Early Access version?

“Grey Hack is in Alpha status as there are some core features to be implemented. Although you can already use several hacking techniques and perform some missions. You can also freely explore the world in single player and multiplayer mode.

The multiplayer mode is functional at the same level as the single player mode. Currently there is only one available online server, although I plan to allow players to create their own dedicated servers.

In the current version, the operating system of the game, including its UI, is quite functional, as well as the terminal commands, available programs and network connections. Although the interaction between players is still very limited.

Keep in mind that since the game is in its Alpha version, due to development aspects, single player and multiplayer savegames can be deleted in future updates.”

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

“The price will increase when the game leaves early access.”

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

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

I plan to 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 game.

You're a hacker with full freedom to act as you want on a vast network of computers procedurally created.

The interface of the game is similar to a current desktop operating system. The file explorer, the command terminal or text editor are some of the programs that will be available from the start of the game. As you improve your skills you will encounter new utilities may install and use.

In Grey Hack, terminal has a fundamental role, it is also based on actual unix commands and will be an indispensable tool to perform successfully hacking actions.

Early Access Main Features

  • Simulator based on real UNIX commands.
  • Share the same world with other players online.
  • World generated procedurally.
  • Online data persistence, allowing you to continue later in the same world and with the same computer after leaving the game.

General Development Plan

The following features are not yet included in the game. During the development in Early Access will be completed, expanded and improved based on feedback from the community.

One of the main objectives of the development is that each player action influence the world and therefore the other players.

For example, you will be able to act on your own benefit, even if you cause collateral damage, help the authorities stop criminals or simply keep a low profile and take advantage of the actions of other players.

In future versions of the game, you will have the possibility to join a group of hackers to carry out coordinated attacks or even create your own group in which you will be able to recruit other players.

Currently each computer in the network is used by at least one user. Each user lives consistently in the world; go to work, shop online, etc.
In future versions of the game you will be able to directly or indirectly influence the lives of these people depending on what you do.

This concept of action-reaction is going to be expanded and completed throughout the development in Early Access.
