The nightly build is open to everyone featuring Tutorial rework, Procedural Missions, improvements in Greyscript and more!

Note that the Nightly version is unstable, may contain game breaking bugs and the savegame can be deleted frequently. So It is not recommended for new players.

The nighly build is designed to help report bugs and provide feedback while the update is being completed before it is moved to the public branch.

Important: Changing to the nightly build removes the savegame from the Single Player mode of the Public build and vice versa. Multiplayer mode progress is not deleted even if you switch from one build to another.

Visit the official Discord[discord.gg] of the game for more information, support and the latest news from the nightly build.

Let's review the main points and then the changelog with the general summary.

The tutorial has been expanded and improved, covering key parts of the game that were previously omitted or barely mentioned. Additionally, in the Tutorial settings window, you can choose which specific part of the tutorial you want to repeat, although you must first complete the Tutorial in its entirety for this option to be unlocked. During the nightly build, the tutorial will be refined and completed based on the feedback received.

Initially it wasn't planned, but instead of the original plan to add some more static missions in the Hackshops and PoliceStations, I decided to experiment with Procedural Missions, as they were going to scale much better with the player's level, and it also allows for easy expansion with updates to improve the variation over time.

The structure of procedural missions is similar to the Hidden and Karma missions. To complete the mission, you must investigate and gather clues to progress through the mission across various networks and devices to complete it. The higher the mission level, the longer the mission will be. Currently there are 3 procedural mission archetypes: Fraud, Sabotage, and Corporate Espionage, but during the nightly build, an additional archetype will be added, along with expanding the existing ones.

Procedural missions can currently only be started from Hackshops, using the usual missions panel. They will be added to PoliceStations later on.

For testing purposes, in the Nightly build, you can accept any mission even if the level is above yours. In the public version, you will only be able to accept missions that are equal to or below your level.


The new method poll_input has been added, which allows capturing keyboard input in a non blocking way. This means that while user_input pauses the script waiting for the player's response, with poll_input the script can be doing other things like animations while waiting for the player's input. This addition can provide a lot of flexibility to the menus of custom programs or even Bash itself. You can view the details of poll_input in the Manual or from CodeEditor.

Here is a summary of the changes that this version brings. Some elements are not finalized, and will be completed during the public nightly build such as the balancing and redesign of the stock system and more QOL improvements.


- Tutorial rework.

- Various improvements to the Manual, including a navigation system with history similar to the one used in FileExplorer. Some Manual entries now include hyperlinks that can take you directly to other pages within the manual. In addition, some tutorial windows now include hyperlinks that allow opening specific sections of the manual directly.

- Migration to Unity’s integrated localization system, with several improvements and fixes for keyword highlighting issues, while maintaining compatibility with community translations from the workshop. However these translations will need to be updated by their authors in order to apply the highlighting fixes.

- Implemented Procedural Missions.

- Redesigned the HTML of the in-game web pages.

- Added a new method poll_input to capture input without blocking script execution. Documentation is also available.

- Added support in get_abs_path for the ~ character indicating the home directory of the active user.

- It is now possible to change the owner, group, and permissions of a file from the UI, in the Properties window.

- When a new world is created, the first 6 versions of all libraries are generated. The first time a new world is started, it may take a little longer to load.

- Increased the rewards of Hidden/Karma missions so they are closer to those of procedural missions with a similar difficulty.

- Reporting a crime or informing the victim now also grants experience in addition to karma.

- Blackmail now offers a partial cash reward adjusted to the mission, equal to 40% of the total reward.

- Blackmail rewards and victim report rewards can now only be obtained once to prevent abuse.

- Stability improvements in Notepad/CodeEditor.
