📦 Programs

“Every Netrunner’s arsenal is only as good as their loadout.”

Programs are a Netrunner’s tools for combat, defense, and exploration. They are loaded onto your Cyberdeck (limited by slots) and must be Activated (Rezzed) to use.


đź“‹ General Rules

  • Activating/Deactivating a Program costs 1 NET Action — no roll required, it just works
  • Each loaded Program can only be Activated once per Meatspace Round
  • A Rezzed Program cannot be Activated again until it’s Deactivated first
  • Attack Programs auto-Deactivate after use
  • You can run multiple copies of the same Program and effects stack (unless noted otherwise)
  • Installing/Uninstalling a Program takes 1 hour

Reading Stats

StatMeaning
ATKBonus to your attack roll when using this Program (Interface + ATK + 1d10)
DEFBonus to the Program’s defense roll when targeted by Anti-Program attacks
REZHit Points — when reduced to 0, the Program is Derezzed (disabled, 2 NET Actions to restart)

Why REZ Matters on Non-Combat Programs

Even Boosters (REZ 7) and Defenders (REZ 7) can be targeted and Derezzed by Anti-Program Black ICE like Killer (4d6), Sabertooth (6d6), or Dragon (6d6). Worse — if Anti-Program ICE’s damage would Derezz your Program, it’s Destroyed instead (permanently deleted). Protect your loadout or carry backup copies.


🔋 Boosters

Boosters provide ongoing passive bonuses while Rezzed. Activate them before you need the bonus — it costs a NET Action, so plan ahead. Multiple copies of the same Booster stack.

See Ya00720eb+2 to all Pathfinder Checks
Speedy Gonzalvez007100eb+2 to Speed (encounter checks vs Black ICE)
Worm00750eb+2 to all Backdoor Checks

Booster Strategy

  • See Ya is arguably the most important — Pathfinder lets you see ahead, and higher checks mean seeing more floors and past stronger Passwords
  • Speedy Gonzalvez helps you win the Speed Check when encountering Black ICE, avoiding free hits
  • Stacking works — 2 copies of See Ya gives +4 to Pathfinder

🛡️ Defenders

Defenders protect you from damage while Rezzed.

Critical limitation: Only 1 copy of each Defender can be running at a time, and each copy can only be used once per Netrun — if you Derezz and re-Rez the same copy, it won’t protect you again. Bring multiple copies if your deck has the slots.

Armor00750ebReduces all brain damage received by 4
Flak00750ebReduces ATK of all Non-Black ICE Attacker Programs against you to 0
Shield00720ebBlocks the first successful Non-Black ICE attack entirely, then auto-Derezzes

Defender Strategy

  • Armor is your bread and butter. Rez it before entering any floor with Black ICE — it reduces ALL brain damage by 4
  • Shield is cheap insurance. It blocks one hit entirely, then self-destructs
  • Flak specifically counters enemy Netrunner Attacker Programs — useless against Black ICE, but invaluable in Netrunner-vs-Netrunner fights
  • Since each is “once per Netrun,” bring multiple copies if your deck has slots

⚔️ Anti-Program Attackers

Weapons against Black ICE and other Programs. After attacking, they auto-deactivate. Class-restricted: cannot target Netrunners.

Sword10050eb3d6 REZ vs. Black ICE, 2d6 REZ vs. Non-Black ICE Programs
Banhammer10050eb3d6 REZ vs. Non-Black ICE Programs, 2d6 REZ vs. Black ICE

Anti-Program Strategy

  • Sword is your main weapon — it does 3d6 vs Black ICE (the most common threat)
  • Banhammer is the reverse — better vs Non-Black ICE Programs. Carry one for Netrunner-vs-Netrunner fights
  • Since they auto-deactivate, you need to re-Activate each Round. Carry multiple copies for sustained combat
  • Both have ATK 1, adding to your hit roll

đź’€ Anti-Personnel Attackers

Weapons against enemy Netrunners. After attacking, they auto-deactivate. Class-restricted: cannot target Programs or Black ICE.
