As the name suggests, Hacknet belongs to a class of games that let you perform hacking. These are not your everyday shooting or racing games and require a particular skill to play. If you’re looking for more games like Hacknet then I have prepared a list of similar games that you might like.
Hacknet Labyrinths

Hacknet Labyrinths is not a sequel to the game, but it sure feels like one. It was released as downloadable content (DLC) and not as a separate game.

Developers have also added more secrets, UI themes and a fresh soundtrack which will get you in the groove for hacking.
