Walkthrough Hacknet begins with an automatic message addressed to the player. It states that it was sent due to the death of Beat, whose death will need to be investigated. After this, the program will begin a chain of simple missions aimed at training the user. After successfully completing the training campaign, Bit will offer to join a squad of hackers called Entropy.

The gameplay is simulated in the style of a Unix operating system, but each aspect of the interface is presented as a separate window, lined with tiles. Each object has from 2 to 4 mosaic configurations with the original appearance and colors used in construction. The walkthrough focuses on continuously preventing connection rollback between the target and intermediate systems. The countdown will not give the right to replay, which is why the user will need to make quick decisions.

If a gamer gains superuser rights, he will have access to the PC file system. This will give you the opportunity to solve the exact problems yourself, although the exact goals differ for each mission. A certain chain of commands will help unlock access to one or several system files at once. Special interfaces related to database and email require a special approach for hacking.
