Matrix Hacking

Lore & Background

In the Shadowrun setting, the Matrix is not merely the internet—it is a parallel digital dimension where data has a quasi-physical form. Hackers do not type commands; they project their consciousness into a landscape of glowing geometry, navigating through layers of code as though walking through a neon-lit city. Every corporate server is a fortress, every data packet a courier running through hostile streets. The Matrix is where the mundane digital world of the 2070s becomes a realm of genuine danger, because the constructs that defend it can reach back through the datajack and burn the hacker's neural pathways.

Intelligence Constructs are the enforcers of this digital world. A simple Daemon might patrol a corporate subnet like a bored security guard, while a Virus strips away your programs one by one. But Black IC is the thing every runner fears: a construct so aggressive, so intelligent, that it does not merely lock you out—it hunts you, and if it catches you, it fries the brain behind the datajack. In the lore of the setting, there are runners who jacked into a single Black IC and woke up in a hospital with half their memories gone, or who never woke up at all.

The social and economic weight of hacking in Shadowrun is enormous. Corporate data is the lifeblood of the megacorporations that rule the world, and a single successful hack can shift power between nations. Yet the Matrix is also the domain of the Matrix itself as a semi-sentient entity in some lore interpretations, and of the digital ghosts—daemons, sprites, and even the occasional lost spirit—that drift between the layers of code. Hacking is never just a technical exercise; it is an incursion into a space that has its own ecology, its own politics, and its own lethal inhabitants.

In Their Own Story

The neon bled through the blinds in strips of magenta and cyan. Kira didn't blink. She hadn't blinked in eleven seconds, and in the Matrix, eleven seconds was an eternity.

Her datajack hummed against the base of her skull, a cold pressure like a thumb pressed to the inside of her jaw. The corporate subnet unfolded before her—not as pixels, but as a vast cathedral of translucent blue geometry, each server a floating monolith, each data stream a ribbon of light threading between them. She was small here. A mote of consciousness in a space that stretched to infinity.

Then the Daemon noticed her.

It was a simple thing—a geometric shape, no more complex than a rotating icosahedron, but it moved with purpose, and its edges were sharp. Kira fed it a Virus from her program pool and watched it dissolve in a shower of static. One down.

The second shape that emerged was not a Daemon. It was not a Virus. It was a shape that had no name in any of her training manuals, and it was looking at her with something that felt, impossibly, like recognition.

Black IC.

Kira's fingers—still in the physical world, still in the cramped apartment above the noodle shop—were already reaching for the emergency disconnect. But her mind, her real mind, the one currently standing in that cathedral of light, was already running. The Black IC was three constructs away. Four. It was accelerating.

She had maybe six seconds. Maybe five.

Kira smiled, and in the Matrix, the smile was a crack in the geometry of the world.

Jacking In and the Hacking Sequence

To begin a hack, the character must have a Datajack (or, in earlier editions, a physical Deck) and must declare the target system. The GM determines the Matrix Rating of the target and the ICs present. The hacker then chooses an action—Scan, Hack to Control, Hack to Copy, Hack to Delete, Hack to Trace, or Hack to Counter-Trace—each with its own base time cost measured in turns.

Rolling the Hack

The hacker builds a d6 pool: Matrix Rating + Computer skill (or the applicable skill for the action). The GM sets a target number, typically 5, modified by the difficulty of the task and the ICs in play. On each turn, the hacker rolls the pool; successes (dice meeting or exceeding the target number) advance the action. The action completes when the number of successes equals the action's difficulty. Glitches (no successes and at least one 1) can cause complications, including Black IC engagement.

ICs and Black IC

ICs act on their own turn, attempting to disrupt the hacker's progress, delete programs, or initiate a Trace. Black IC is the escalation: once engaged, it acts every turn, and if it accumulates enough successes against the hacker before the hacker disconnects, it deals brain damage. This creates a genuine time-pressure dynamic absent from most TTRPG hacking systems.

What Makes It Distinct

Compared to generic d6 cyberpunk TTRPGs, Shadowrun's hacking is a spatial, time-based duel with persistent adversaries, not a single opposed roll. The presence of magic in the same game means a hacker might be fighting a Matrix sprite or a daemonic construct alongside corporate ICs, blending the cyberpunk and fantasy pillars in a way no purely technological system replicates.

Did You Know?

• In Shadowrun, Black IC does not just lock you out of a system—it can cause permanent brain damage or death by overloading the neural pathways behind the datajack, making hacking a genuinely lethal activity in the setting
• The Matrix in Shadowrun lore is sometimes described as having its own semi-sentient ecology, with daemons, sprites, and other entities inhabiting the digital space alongside corporate ICs.
• Shadowrun's hacking system predates most cyberpunk TTRPGs' dedicated hacking mechanics, having been a core feature since the franchise's 1989 debut, long before 'hacking minigames' became a genre staple.
• In earlier editions, hackers used physical Decks with a Matrix Rating; the shift to Datajack cyberware in later editions removed the need for bulky hardware and made jacking in a more intimate, body-modification-based ac
