It is based on Richard Garfield's Netrunner collectible card game, produced by Wizards of the Coast in 1996.

Deluxe expansions originally focused on two factions (one Corporation and one Runner) and contain three copies of 55 cards.

Null Signal Games supports and maintains multiple formats for organized play.

The Standard format is the most popular among players, and contains sets from both the FFG and NSG eras of Netrunner.

As of March 28, 2024, Standard contains the following sets: The release of The Automata Initiative in July 2023 caused the Flashpoint Cycle and Data and Destiny to rotate from the format.

In September 2024, the Null Signal Games Balance Team introduced a ban list and deckbuilding restrictions for the Startup format.

These include, but are not limited to, Snapshot, Random Access Memories, and Draft, as well as many player-created formats.

National, regional, and store championships precede this; each event's first-place winner receives a first-round bye in the following level of tournament play.

Organised Netrunner events include a series of casual and competitive tournaments held every year, leading up to the World Championships, as detailed in the Null Signal Games Organized Play Policies.

Proxies (printed stand-in cards) are usually permitted, as long as they are acceptable according to the Organized Play Policies.
