Netrunners are a type of character in the Cyberpunk universe who specialize in computer systems, programming languages, and writing or modifying viruses. They are essentially hackers who can manipulate electronic devices, such as electric cars or assault drones, and gain control over them. Netrunners are also skilled in extracting information, making them suitable for roles as information brokers.

Netrunners use cyberdecks, which are electronic mind-modems, to interface with computers, electronics, and associated programming. They can control and manipulate these systems to achieve their goals. Netrunners can also use quickhacks, which are similar to spells in a fantasy game, to perform various actions such as disabling security systems, distracting enemies, or even frying someones brain.

Netrunners can take on different roles depending on the task at hand. They can act as frontliners, support, or information brokers. They are versatile and highly in-demand, but there is also an inherent risk and danger to being a netrunner. Netrunners are the rulers of Cyberpunk 2077s dystopian, digitalized world, and they are some of the most influential people in Night City. However, players cannot actually do any netrunning in Cyberpunk 2077, which is a significant disappointment.
