This section contains the official rule clarifications and enhancements for Android: Netrunner. Used in conjunction with the core set rulebook, these clarifications and enhancements should enable a player to navigate through the most complex situations that can arise while playing the game.
The word "additional" denotes an ability that modifies another ability or a game state. The additional ability is resolves simultaneously with any ability it is modifying, and under the same conditions as that ability.
Whenever there is an "If successful…" effect tied to the outcome of a run, the run itself must have been successful against the specified server(s), if applicable. If the Runner initiates a run against the specified server but ends the run on a different server, the "If successful…" effect does not resolve when the run is successful.
If the ability including "If successful…" does not specify a server, then it does not matter if the attacked server is changed during the run, and the ability resolves as normal.
Any time an ability is optional, the player resolving the ability is "using" the ability. This includes all paid abilities and all optional conditional abilities (triggered abilities that use the word "may" or "allows").
A player can only trigger an action or ability if its effect has the potential to change the game state. This potential is assessed without taking into account the consequences of paying play, install, or rez costs or triggering any further abilities.
If during the resolution of an ability another ability meets its trigger condition, then a "chain reaction" is created. The ability that just met its trigger condition resolves immediately following the active effect on the current ability. If this ability results in another ability meeting its trigger condition, then that ability is also "chained." Resolve all the abilities from the most recent trigger condition before continuing.
Conditional abilities resolve after meeting their trigger condition. However, if the game state advances past the trigger condition due to simultaneous effects or a chain reaction, then the triggered ability cannot be resolved.
The Runner can boost the strength of his icebreakers outside of an encounter with a piece of ice. However, unless that icebreaker says otherwise, its strength is immediately reset to its previous value.
The Runner can only break the subroutines on a piece of ice during step 3.1 of a run. If step 3.1 of a run is not reached, such as when bypassing a piece of ice, then no subroutines on that piece of ice are broken.
Prevent/Avoid effects take priority over conditional abilities that would trigger from whatever is being prevented or avoided, except when a conditional ability uses the word "additional". An "additional" conditional ability occurs simultaneously with the trigger condition and can be prevented/avoided along with the trigger condition.
A prevent/avoid effect can only be used when the thing it is preventing/avoiding is resolving.
"Hosting" is the result of placing a card, counter, or token on top of a card, creating a relationship between the host card and what is hosted. If a card allows other cards to be hosted on it, those cards must be hosted on the card when they are installed, unless a card says otherwise.
Hosted counters or tokens can be spent without affecting their host. If a trigger cost requires one or more hosted counters or tokens, those counters or tokens are "spent" by being returned to the token bank from the card the ability appears on.
If a host is trashed or uninstalled, all cards, counters, and tokens hosted on it are also trashed. This cannot be prevented. If a host Corp card is derezzed, all cards, counters, and tokens hosted no it remain hosted.
The state of hosting is distinct (but not exclusive from) the state of installing. Most cards are hosted on another card when they are installed. If a card is hosted but not installed, the card is inactive.
The Crop cannot choose to destroy a server when installing cards; at least one card must be installed for other cards in or protecting that server to be trashed.
If there are no cards installed in or protecting a remote server, then the server immediately ceases to exist. If a server ceases to exist during a run, then the run ends after any currently open paid ability windows close. Unless the run has passed step 4.4 of the timing structure of a run, it is not considered to be successful or unsuccessful.
Recurring credits are placed on a card when the card becomes active, and can be used immediately. Recurring credits do not stack; a player replaces recurring credits up to the number listed on the card when his or her turn begins. This occurs at step 1.2 of the Runner's turn, before any conditional abilities can be triggered. Recurring credits are only ever replaced up to their current value, not removed.
If a Corporation card is not visible to the Runner when it is trashed or discarded, then it is sent to Archives facedown. If a Corporation card is visible to the Runner when it is trashed or discarded, it is sent to Archives faceup.
If a specific card or card type in an inactive state is chosen by a card effect, the Corporation must show that card to the Runner without changing its faceup or facedown status. The Corporation only reveals the card if it was facedown and the effect says he must reveal it.
If a mandatory infinite loop is created (a player cannot choose to stop resolving the loop) then the player who is resolving the loop chooses a number. The loop instantaneously resolves that many times, and then ends.
If an optional infinite loop is created (a player can choose to stop resolving the loop) during a run, then the Runner must jack out unless another card ability prevents him or her from doing so. If the Runner cannot jack out, then it is the Corp's responsibility to end the loop by letting the Runner continue the run.
Ice is always approached according to the position it occupies protecting a server, ranging from the outermost piece of ice to the innermost piece of ice. If there is one piece of ice protecting a server, that piece of ice is both the outermost and the innermost piece of ice. The Runner always starts at the outermost position during a run. After passing a piece of ice, the Runner approaches the next most-innermost position, even if he or she has already approached it, or there is another piece of ice outside of that position which has not yet been approached.
Runner cards that are installed or turned facedown do not have a type or subtype, and their abilities are not active. The Runner can look at his or her facedown cards at any time. If a facedown Runner card is trashed, it is turned faceup when entering the heap. A Runner card turned facedown is no considered to be uninstalled.
If the card title referenced on a card matches the title of that card, and the reference is not plural and/or does not include an additional modifier (e.g., "other copies" or "all"), then the card title only refers to that copy of the card, and not to any other copies of it.
If a card copies the text of another card, and the copied text includes a self-reference, the copied text does not function unless it explicitly says so.
Parasite cannot be hosted on Djinn. A card or counter can only be hosted in one place at a time, and Parasite has the restriction that it must be installed on a piece of ice.
If a piece of ice hosting Parasite is derezzed, the Parasite continues to collect virus tokens, but the hosting ice has no strength while derezzed and therefore cannot be trashed by Parasite unless it is rezzed again.
Femme Fatale does not need to match the strength of a piece of ice in order to bypass it.
The Runner can spend the credit from Cyberfeeder to pay for the bypass ability.
If Femme Fatale is uninstalled, the Runner cannot bypass the ice chosen by the Femme Fatale when it was installed: the ability is no longer active since the card is no longer active. Even if that copy of Femme Fatale is re-installed, it is treated as a ‘new’ copy and cannot bypass anything other than the ice chosen when it was just installed.
If Mandatory Upgrades is forfeited, the Corp loses the additional click immediately. The Corp cannot choose to spend the additional click before the forfeit, except as part of his last action (at which point it has already been spent, and there is nothing left for the Corp to lose). Each player should keep a running total of each click that is available for them to spend, rather than look at clicks individually.
TMI can be rezzed multiple times while the Runner approaches it. Timing structure of a run 2.3 is a window that allows the approached piece of ice to be rezzed. There is no limit to the number of times a Corp can rez an approached piece of ice if it is derezzed during this window.
If there is an icebreaker already installed on Dinosaurus, the Runner can install a different icebreaker onto Dinosaurus, trashing the previously installed icebreaker.
If the Runner has no free MU but a Dinosaurus that is not currently hosting an icebreaker, he can install an icebreaker on Dinosaurus without trashing a program. Declaring that you are hosting it on Dinosaurus as part of the install action, and so the memory cost of the program does not need to be taken into account.
The Runner may use the first ability on Personal Workshop to host a program or a piece of hardware on it. Cards hosted by this ability are not installed, and therefore are inactive.
The Runner can pay to remove a power counter from a card hosted on Personal Workshop as a paid ability. A program installed from Personal Workshop follows all the normal install rules; you must trash already installed programs to make room for the new one, if necessary.
When there are no power counters on a program or a piece of hardware that has a play restriction on it that cannot be met (such as a Parasite with no rezzed ice to be hosted on or a console when there is already a console installed), that program or piece of hardware is trashed instead of being installed.
If Personal Workshop is uninstalled, all cards hosted on it are trashed and all counters on those cards are removed.
Looking at the top 3 cards of R&D does not remove the cards from R&D. The cards are still in R&D and able to be affected by operations played with Accelerated Diagnostics.
Each operation the Corp looks at can be played in any order. The Corp does not have to play the topmost operation first.
When the Corp plays an operation, he fully resolves it before playing another one or trashing the rest of the cards.
If any o the 3 cards looked at are no longer in the top 3 positions of R&D (as determined when Accelerated Diagnostics was played), then those cards cannot be played.
The Corp can only play and look at the top 3 cards (as determined when Accelerated Diagnostics was played. Even if other cards are moved into the top 3, those cards are not eligible to be played/looked at by the Accelerated Diagnostics.
If one of the operations played shuffles R&D, the remainder of Accelerated Diagnostics' effect is ignored.
If Security Testing is uninstalled after a server is chosen, its ability cannot replace accessing cards if the first run on the chosen server is successful; the ability is no longer active since the card is no longer active.
The run is considered neither successful nor unsuccessful for the purpose of future card abilities, even if Crisium Grid is later trashed. (eg Tennin Institute will trigger if the only successful run the Runner made was against a server with a rezzed Crisium Grid.
Restrictions which require a successful run (eg Emergency Shutdown, Data Leak Reversal) cannot be used if the successful run was against a server with a rezzed Crisium Grid.
If the Corp has multiple copies of Daily Business Show installed, the abilities stack on top of each other (e.g. two copies result in the Corp drawing 3 cards and adding 2 to the bottom of R&D).
The Corp does not have to tell the Runner whether he or she kept the first or second card drawn. The Corp must keep the two cards discrete from the rest of his or her hand, though, when deciding; the Corp can shuffle the two cards together to obscure which card was taken.
The subroutine that resolves is not considered to be on Wormhole (e.g. when the Corp uses Wormhole with cards like Data Raven or Viktor 2.0, the power counters are placed on those cards and not on Wormhole).
When encountering an Archangel during access, the Runner follows timing step 3 of a run, ignoring the portions about approaching ice/the server.
If Archangel is encountered while accessed and it is moved from its position as determined when accessed (e.g., from R&D being shuffled during the encounter or from Archangel being trashed from HQ by Utopia Shard during the encounter), then the encounter immediately ends and any currently open paid ability windows close.
Archangel is not considered to be rezzed during its encounter, and cards that interact with rezzed cards, e.g., Datasucker, cannot affect it.
If the Runner steals an agenda from Jinteki using the core set identity, but has no cards in hand, who wins if the agenda gives the Runner his seventh point?The Runner wins the game. Whenever a player has 7 or more agenda points in his score area, the game immediately ends. The game ending takes precedence over any conditional ability that triggers when an agenda is stolen.
When a piece of ice allows the Runner to break subroutines on it by spending clicks, does the Runner have to match the strength of the ice before using this ability? No. The Runner only has to match the strength of a piece of ice with an icebreaker that he is using to interact with the ice. This ability allows the Runner to break subroutines by spending clicks without using any icebreakers.
Can the Runner use Datasucker to reduce the strength of a piece of ice before an ability on that ice triggers when it is encountered (such as a Tollbooth)? No. Tollbooth ends the run unless the Runner pays 3 before the Runner has the opportunity to use a paid ability. See step 3 of a run.
Can the Runner combine multiple effects to make a run, like using both Sneakdoor Beta and Account Siphon? No. Using each of those cards is an action, and a player cannot take an action during the resolution of another action.
The rules state that "The Runner cannot jack out while approaching the first piece of ice during a run." Can the Runner jack out after the subroutine on Cell Portal resolves and he is approaching the outermost piece of ice protecting the server? Yes. "The first piece of ice" refers to the first time a piece of ice is approached during a run, and not the ice itself. The Runner approaches the ice and has the opportunity to jack out.
There is a Parasite with 1 virus counter hosted on a rezzed Enigma, and the Runner has an Ice Carver installed. If the Runner encounters Chum, does not break its subroutine, and then continues the run and encounters Enigma, is the Enigma trashed? No. Chum's ability is a required conditional effect that creates a constant +2 strength effect. When the Runner encounters the ice, both modifiers (Chum at +2 and Ice Carver at -1) apply at the same time and the strength of Enigma would be 2.
If the Runner takes 4 brain damage from a single source, how many brain damage tokens would he get? The Runner takes 1 brain damage token for each point of brain damage he suffers, even if it was suffered all at once. The Runner would get 4 tokens to mark the brain damage he has suffered.
Where is an upgrade installed in a remote server? An upgrade is installed in a remote server in the same position as an agenda or asset. The Runner should not be able to tell what type of card is installed in a remote server by its position. This is different than installing an upgrade in a central server, where it is always installed in the root.
Can the Runner use multiple icebreakers on a single piece of ice? Yes, although there are few situations where this is beneficial. But the Runner cannot use one icebreaker's strength to allow another icebreaker to interact with the ice.
Can the Runner trash an accessed card with Demolition Run before any "when accessed" conditional abilities resolve? No. The card must be accessed before Imp, Demolition Run, or any other similar effect can be used to trash it, just as if the Runner was paying its trash cost.
Can the Runner install a program if he has no more available memory units? Yes. The Runner can trash any number of already installed programs before installing a new one (and must if there is not enough space for the new program). So if the Runner has no free MU, he can initiate an install action, trash any number of programs to free up MU, and then install the new program.
The Runner chooses an unrezzed Archer as the target of a Forged Activation Orders. Can the Corp choose to rez Archer, but then decline to pay the additional cost of forfeiting the agenda? No. If the Corp chooses to rez Archer, then as part of this choice he must pay 4 and forfeit an agenda. Otherwise, the ice is trashed.
Can the Corp rearrange his installed cards within a single server, to obscure the order that he installed them in? The Corporation must keep the order of his installs clear to the Runner; he cannot rearrange cards in servers however he likes.
If the Runner gains a click with Joshua B. and then trashes the card using Aesop's Pawnshop, would he still take a tag at the end of the turn, considering Joshua B is no longer active? Yes. The Runner would still take the tag, even though Joshua B. is no longer active, because "If you do…" is part of the same ability. Once an ability is triggered, it remains active and resolves unless prevented or avoided.
Can the Runner use New Angeles City Hall to avoid the tags from an Account Siphon if they have 0 credits when the ability resolves? No. The gaining of the credits and the taking of the tags resolves at the same time, so the Runner cannot use those credits to avoid the tags.
If the Corp uses Efficiency Committee for extra clicks, can he then play Shipment from Kaguya and Trick of Light to place/move advancement tokens during that turn? Yes. Placing or moving advancement tokens on a card is different than advancing it, and Efficiency Committee only stops the Corp from advancing cards.
The Runner does not break a subroutine that specifies "Trash 1 program." Who chooses the program to trash? The Corp chooses which program to trash. Unless otherwise noted, each player makes the choices required by the effects on his cards.
Can the Runner use the recurring credit on Cyberfeeder to pay for using Femme Fatale's bypass ability or Darwin's gaining counters ability? Yes. Triggering any ability on an icebreaker is considered to be using it.
How does Rielle "Kit" Peddler's ability interact with bypassing a piece of ice? Is there anyway to bypass a piece of ice and make the next piece of ice a code gate? There is no way to bypass a piece of ice and then make the next piece of ice a code gate. Rielle "Kit" Peddler makes the first piece of ice encountered a code gate, and this is a constant ability. The Runner encounters any ice bypassed, and cannot choose to resolve the bypass ability before Kit's constant ability, because the constant ability is always active.
If the Runner has The Source installed and plays a Notoriety, does the clause "Add Notoriety to your score area as an agenda" cause The Source to be trashed? No. Adding Notoriety to the Runner's score area is not the same as scoring or stealing an agenda, and so does not trash The Source.
The Runner encounters Heimdall 1.0 and uses a click to break the first subroutine. If the Corp rezzes a Tyr's Hand and uses its ability to prevent that break, can the Runner spend another click to rebreak the subroutine? Yes. Tyr's Hand prevents a subroutine from being broken once, but the Runner can break the subroutine again.
If the Runner encounters Heimdall 2.0 and uses two clicks to break the first two subroutines, and the Corp uses a Tyr's Hand to prevent one of them from being broken, can e3 Feedback Implants be used to break that subroutine again? Yes. Both subroutines are broken at the same time, and so the Runner can respond to the broken subroutine with e3 Feedback Implants.
The Runner encounters Heimdall 2.0 and spends two clicks to break both of the first two subroutines. He then uses e3 Feedback Implants to break the third subroutine, but has that break prevented by Tyr's Hand. Can the Runner use e3 Feedback Implants again, or has the chance to use it now passed? Yes, the Runner can use the e3 Feedback Implants again.
How does Project Ares interact with Sacrificial Construct? Can the Runner choose to trash a Sacrificial Construct, and then trash that Sacrificial Construct to prevent another card from being trashed by Project Ares? Yes. All installed cards being trashed by Project Ares are chosen at the same time, and the prevent ability on Sacrificial Construct can be resolved to prevent another card from being trashed.
The Runner has Blackguard installed and exposes an Archer. Is the Corp forced to rez the Archer? Blackguard only forces the Corp to pay the rez cost, if able. The Corp does not have to rez the Archer because he can decline to pay the additional cost of forfeiting an agenda.
The Corp has two copies of Director Haas installed, one rezzed and one unrezzed. The Corp spends four clicks and then rezzes the second copy. Does the Corp have an additional click to spend? No. Clicks are tracked as a running total and not individually. The Corp still has 4 clicks to spend on his turn, and he has spent 4 clicks, whether or not the additional click came from a different card.
If the Runner did not break a subroutine on Hudson 1.0 and accesses an installed Toshiyuki Sakai, can he access the swapped-in card? No. The Runner cannot access the card swapped with Toshiyuki Sakai because it is a new card and he has reached his access limit.
Can I spend credits to boost the strength of an icebreaker, or break a subroutine on a piece of ice, if I am about to encounter a Tollbooth during step 2.3 of a run? The Runner cannot break subroutines outside of step 3.1 of a run, but he or she can boost the strength of an icebreaker.
The Runner has Security Testing and Aesop's Pawnshop installed. At the start of his turn, the Runner names a server for Security Testing, then sells it to Aesop's Pawnshop. The first time he makes a successful run on that server, does he gain 2 credits instead of accessing cards? No. A conditional ability can only resolve if the card it is on is active when the trigger condition is met, and Security Testing is no longer active after it is trashed. Security Testing has two conditional abilities on it (like Femme Fatale), unlike Joshua B., who has one.
The Runner uses Femme Fatale to bypass a Komainu for 0 credits. If there is a Chum installed before the Komainu, are the 0 subroutines on Komainu broken, or does the Runner take the 3 net damage? The subroutines are not broken because the ice was bypassed, and the Runner takes 3 net damage.
If Security Testing is used on HQ and the Runner plays an Account Siphon, can he choose which replacement effect to use? No. Security Testing triggers at step 4.4 of a run, and replaces the access. Security Testing is also a required ability and the Runner cannot choose to not use it. Account Siphon does not trigger until step 4.5 of the run, at which point Security Testing has already resolved.
If the Runner uses a Tinkering on a Wendigo with one advancement token on it, is the Wendigo a code gate? Yes. Gaining and losing subtypes are tracked as a running total, but having the subtype is a binary state. In this scenario the Wendigo had two code gate subtypes and loses one, meaning it is still a code gate.
If the Corp uses the ability on The Foundry during the resolution of an Accelerated Beta Test, what happens? Each piece of ice is installed and rezzed one at a time. So the Corp installs the first piece of ice and then uses The Foundry to search R&D for another copy. This results in shuffling the other two looked at cards into R&D (they never actually leave R&D), preventing them from being either installed or trashed.
Can the Corp add subroutines to a piece of grail ice in any order (by using other grail ice)? Yes. The Corp can add subroutines to grail ice before or after any subroutines, including the subroutine printed on the card.
If the Runner has 2 credits and an active Net Celebrity, does he have to pay 3 credits (including the Net Celebrity credit) when encountering a Tollbooth? Yes. Cards with recurring credits (like Net Celebrity) or temporary credits (like Ghost Runner) have to be used if the requirement to use the credits on the card is met and an effect requires credits to be paid.
If the Runner chooses Archives for Security Testing, and the Corp has Crisium Grid installed there, can Security Testing be used? When the Runner makes a run on a server with Crisium Grid, the run is still successful but it is seen as neither successful or unsuccessful for the purposes of card abilities. Security Testing does not see that a successful run occured. If the Runner trashes the Crisium Grid and then successfully runs on Archives for a second time, the Security Testing triggers because it believes the first run was not successful or unsuccessful.
What happens if the Runner uses Eureka! to install Angel Arena? If Angel Arena is installed using Eureka!, then the X value the Runner chooses to pay is lowered by 10. So if the Runner paid 0 credits, he or she gets 0 power counters, because X was lowered from 10 to 0.
If the Runner has a Hivemind with 1 virus counter on it and an Imp with no virus counters on it, can he use Virus Breeding Ground to move 1 virus counter to Imp? Yes. Imp is considered to have the virus counters on Hivemind on it.
What happens if the Runner steals an agenda worth 3 points, and the Corp plays Punitive Counterstrike with The Board rezzed? Does the Runner take 2 or 3 meat damage if the trace is successful? The Runner would take 2 meat damage if the trace is successful, since the 3 point agenda is currently worth 2 points.
Can the Runner use Incubator to move all the virus counters on Hivemind to another card? If so, does the Runner have to move all the virus counters or can he pick how many to move? Yes, the Runner can and must move all virus counters from Hivemind to the chosen card when using Incubator.
Does Pheromones get a credit on it immediately if installed with a Grimoire out? Pheromones does not get an immediate credit on it with a Grimoire installed. Pheromones becomes active before the conditional ability on Grimoire resolves, and when it becomes active the recurring credits (0) immediately appear. Pheromones still gains the virus token from Grimoire, but the credit for it does not appear until the next turn when the recurring credits are replaced.
If the Runner accesses a Cyberdex Virus Suite from HQ, does the Cyberdex Virus Suite purge virus counters first or can the Runner use a virus counter on Imp to trash it before the purge? The Cyberdex Virus Suite removes the virus counters from Imp first; you cannot trash a card accessed with Imp until after all of the "when accessed" abilities are resolved.
Does Blacklist prevent the Runner from using Same Old Thing to play an event from the heap? Yes. The event must leave the heap when played using Same Old Thing, so while Blacklist is active it prevents the Runner from using Same Old Thing.
Can the Runner use Sacrificial Construct to prevent the trashing or a program on London Library? Yes. Programs on London Library are installed, the Library's effect is a conditional ability that resolves at the end of each of the Runner's turns. So Sacrificial Construct will delay the trash, but London Library will attempt to trash it again at the end of the Runner's next turn.
Can the Runner use Immolation Script during a run in which Eater was used to break a subroutine? No. Eater stops the Runner from accessing any individual cards, and so there is no access to replace with Immolation Script.
If the Runner trashes a Worlds Plaza that is hosting The Board, does the Runner add The Board to their score area? No. Since The Board is not currently being accessed, it is not added to the Runner's score area.
If the Runner takes net damage while both Titanium Ribs and the Chronos Protocol are active, what happens? If it is the Runner's turn, then Titanium Ribs resolves and the Runner chooses which card to trash. If it is the Corp's turn, then the Corp chooses which card to trash.
Can the Corp score a Research Grant, use Team Sponsorship to install another copy of it, and then score the new copy with the ability on the first Research Grant? Yes. The Corp can choose the order in which his or her simultaneous effects trigger.
If the Runner plays Drive By and the Corp uses Zaibatsu Loyalty to prevent the card from being exposed, can the card still be trashed if it is an asset or upgrade? No. The effect does not resolve because Drive By cannot confirm the card to be an asset or upgrade.
If a Runner with no tags accesses a Quantum Predictive Model that hosts Casting Call, does the Corp score the Quantum Predictive Model? No. The Quantum Predictive Model does not resolve if the Runner is not tagged when the access occurs.
If the Runner trashes a Worlds Plaza that is hosting a Hostile Infrastructure, how much net damage does the Runner take? The Runner takes 1 net damage from trashing the Worlds Plaza. The Hostile Infrastructure is trashed by the game (according to the rules for hosting) and not by the Runner.
If a run initiated with Dorm Computer is unsuccessful while John Masanori is installed, does the Runner avoid the tag? No. Dorm Computer's ability only applies during the run, and John Masanori does not trigger until the run has successfully ended.
Can a Runner playing as Kate "Mac" McCaffrey use a DaVinci with 1 power counter on it to install a 2-cost card like Clot? No. DaVinci's ability looks at the install cost of the card while it is in the Runner's grip, before it is installed by triggering the trash ability.
What happens if the Runner accesses an Archangel from R&D during an encounter with a Shiro? If the Corp pays 3 credits, then the Runner encounters Archangel; while encountering Archangel, the Runner is not considered to be encountering Shiro again until the Archangel access ends. Then the Runner continues the previous encounter with Shiro, resolving any other of its subroutines, if necessary, and continuing the run from that position.
