Shadowrun 4th Edition Combat Crib Sheet

Combat Turn Sequence [SR4 p132]:
1.Roll Initiative – Roll Initiative dice pool and add hits to the Initiative rating
2.Begin 1st Initiative Pass - Characters act in order of initiative, highest to lowest
3.Begin the next Initiative Pass – Characters with more than one Initiative Pass act again. Repeat this step, until no characters have any remaining Initiative Passes.
4.Begin new Combat Turn

Actions [SR4 p135 - 138 & 168 - 169]: On a character's Action Phase he can Walk or Run and take actions; either 1 Free action plus 2 Simple actions or 1 Free action plus 1 Complex action.

Free Actions
Call a Shot
Change Linked Device Mode e.g. activate cyberware, change mode on a smartlinked gun
Deactivate Focus
Declare Counterspelling spell defence
Drop object
Drop prone
Drop a sustained spell
Eject smartgun clip

Simple Actions
Activate a Focus
Call spirit on “standby”
Change gun mode manually
Change position / stand up
Command a spirit
Dismiss spirit to “standby”
Fire a weapon (SS, SA, BF)
Insert a clip/ remove a clip
Observe in Detail
Pick Up / Put down object
Quickdraw & fire a pistol
Ready a weapon
Shift to / from Astral Perception
Take aim
Throw a weapon

Complex Actions
Astral Projection
Banish Spirit
Cast a spell
Erase Astral Signature
Fire a weapon (FA).
Fire Mounted Weapon
Fire Vehicle Weapon
Full Defence
Make a hand to hand attack
Reload Firearm
Summon spirit
Use a Skill

Damage [SR4 p152]: Damage is either Physical (P) or Stun (S) and is ticked off on the appropriate Damage Track. A character suffers a -1 dice pool penalty for every 3 full boxes of damage.

Ranged Combat

Attacker Rolls [SR4 p141]: + Agility
Defender Rolls [SR4 p141]: Reaction
(+ Dodge if using Full Defence)
–1 per attack defended against since last action [SR4 p150]

If the attacker gets more hits than the defender he has hit and inflicts damage. A tie indicates that the attack made contact but did no damage (important for some touch based attacks).

Modify DV [SR4 p140]: Damage Value (DV) of weapon + Attacker’s net Hits
Modify Armour [SR4 p140]: Armour rating adjusted by weapon’s Armour Penetration (AP)
Use Ballistic Armour against firearms, Impact otherwise

If the modified DV does not exceed the modified Armour, the attack does only Stun Damage.

Damage Resistance [SR4 p153]: Body + modified Armour rating (Wound Modifiers do not apply)

Each Hit on the Damage Resistance Test reduces the modified DV by 1. The remaining DV is applied as boxes of damage to the appropriate Damage Track.

Melee Combat

As Ranged Combat except for the following:

Attacker Rolls [SR4 p147]: + Agility
Defender Rolls [SR4 p147]: or Dodge + Reaction
(+ Dodge if using Full Defence)
–1 per attack defended against since last action [SR4 p150]

Shadowrun 4th Edition Magic Crib Sheet


Spellcasting [SR4 p173]: Spellcasting requires a Complex action; the actual effects will vary by spell. The magician chooses the Force at which to cast the spell (any Force up to his Magic x2).

Casting [SR4 p173] Spellcasting + Magic (Hits are limited to the Force of the spell)
Resistance [SR4 p173] Attribute defined by the spell + Counterspelling (if allocated, see below)

If the casting Hits exceed the number of hits on the resistance test the spell takes effect. Inanimate objects receive no resistance test however a difficulty threshold must be exceeded.

Resist Drain [SR4 p174] Willpower + Logic for hermetic mages
Willpower + Charisma for shamen

Each Hit reduces the Drain Damage Value (DV) by 1; any remaining DV is applied to the Stun damage Track (or the Physical Track if the Force is greater than the magician’s Magic attribute).

Counterspelling [SR4 p175]: The Counterspelling Skill can be used to defend a magician and his allies from spells. Spell defence must be declared with a free action, and all people being protected must remain within line of sight of the protecting magician. Until the defending magician’s next action, all people protected gain the bonus of the Counterpelling dice in all their spell resistance tests.

If more than one protected person is targeted with the same spell (e.g. an area spell), Counterspelling is rolled only once and the hits applied to all the targets’ resistance tests.

Sustaining Spells [SR4 p174]: This imposes a universal -2 dice pool penalty to tests (except Damage and Drain resistance tests).


Summoning [SR4 p179]: The process of summoning a spirit requires only a Complex action, however only one non-bound spirit can be summoned and utilised at a time, and it will disappear at the next sunrise or sunset. The magician chooses the Force for the spirit (any Force up to his Magic x2).

Summoner Rolls: Summoning + Magic
Spirit Rolls: Force

Each net Hit on the Summoning Test results in one service that the spirit will perform for the magician.

Resist Drain [SR4 p179] Willpower + Logic for hermetic mages
Willpower + Charisma for shamen

The Drain Damage Value (DV) for summoning is equal to twice the Hits scored by the spirit (not net hits). Each Hit scored on the Drain Test reduces the DV by 1; any remaining DV is applied to the Stun damage Track (or the Physical Track if the Force is greater than the magician’s Magic attribute).

Binding [SR4 p180]: A summoned spirit can be bound to allow it to stay around indefinitely (it will not disappear at the next sunrise or sunset). In addition a magician can have a number of spirits bound to him at any one time equal to his Charisma. Binding works like Summoning except for:
The Binding Skill is used instead of Summoning and the Spirit rolls double its Force.
A ritual is required that takes a number of hours equal to the spirits Force.
Ritual materials must be used, costing 500 Nuyen per point of Force

The Astral Plane

The astral plane is another dimension overlaid upon our own. It is the domain of spirits and magic. Magicians can perceive this dimension and are able to view spirits and magic that would normally go unseen. The auras of people can be read to gain information about their emotions, health and nature. Some magicians can separate their astral self from their physical body and travel unheeded in the astral plane, invisible to those in the mundane world.

Astral Perception [SR3 p171]: Astral Perception allows a character to interact with both the physical and astral planes at once. However, whenever the character performs a completely mundane task they suffer a -2 penalty. It takes a Simple action to shift to or from Astral Perception [SR4 p182].

PostSubject: Matrix Crib Sheet   Wed Jul 14, 2010 3:00 pm

The Matrix – Crib Sheet
Computer System & Commlink Attributes [SR4 p212]: All computer systems (generically called nodes), whether they be a personal commlink or a megacorp’s mainframe, have a number of core attributes that define their processing power and speed, transmission range and base security defense.
Response [SR4 p212]: This is a measure of processing power, and is a function of the hardware.
Signal [SR4 p212]: This indicates the transmission power, and again is a function of the hardware.

System [SR4 p213]: System is a measure of the capabilities of the operating system (OS).
System cannot run at a rating higher than the base Response rating of the hardware.
The OS cannot run a program at a rating higher than its System.
For every (System rating) programs running, the computer’s effective Response is reduced by one.
The number of nodes, agents, or drones that a persona may actively subscribe to (access) at any one time is limited to the System x 2. The full subscription list of devices that are allowed to establish communication with the hacker is unlimited, only active subscriptions are limited [SR4 p212].
Firewall [SR4 p213]: Firewall is the operating system’s built in security and acts as a Difficulty Threshold for hackers to hack into the system.
Damage Track [SR4 p213]: In addition to these core attributes a computer system or device also has a single damage track equal to half the System rating (round up) + 8.
A computer system may also be running various programs, including Intrusion Countermeasures, to enable certain functions to be performed more easily and / or to increase security.
PANs [SR4 p19 & p211]: A character’s Personal Area Network (PAN) is a micro-network linking together all of his personal devices using his commlink as the central router and Matrix hub. The commlink thus acts as the “gatekeeper” for all interaction with that character’s devices.
A character can switch his commlink and PAN between 3 different modes as a Free Action.
Active [SR4 p211]: In active mode, you can both access and be accessed by other nodes (PANs, devices, and networks). Certain areas may require your PAN to be in active mode (e.g. airports).
Passive [SR4 p211]: A PAN in this mode can access nodes but cannot be accessed by them without your approval (i.e. it can block spam). PANs in passive mode still show up as active networks if searched for.
Hidden [SR4 p211]: A hidden PAN is invisible to other nodes unless you access them or authorize them ahead of time. Using hidden mode might be considered rude or suspicious.
Account Privileges [SR4 p216]: When a user logs onto the Matrix they can access any public nodes they can reach (like today’s internet) and also log on to any private nodes for which they have a valid account. Account are broadly defined into 3 categories.
Personal: These provide basic privileges to access the files and devices a character needs to do his job. The extent of access typically depends on the user’s position within the organization.
Security: These accounts are given to senior management and the mid-level technical staff. Most security hackers also have security passcodes.
Admin: Only granted to a few users, admin privilege gives you total access, so that any problems that come up in the system can be solved. Admin access authorizes almost any activity, including destruction of important data or actions that damage the system or render it inactive.
Augmented Reality [SR4 p209]: Augmented Reality (AR) is the use of the matrix while still in physical control of your own body. The matrix information overlays the normal sensory input from the world. This overlay is accomplished using cybereyes, glasses, AR gloves etc.
Virtual Reality [SR4 p228]: Virtual Reality (VR) is the complete sensory immersion in the matrix, all of the users real world senses are overridden so that they are only aware of the matrix (-6 dice to real world perception tests). VR matrix use is a lot faster than AR as all actions are performed at the speed of thought. A commlink sim module and either a datajack or trode net is required to use VR.
Cold Sim is standard legal VR, whilst Hot Sim is cranked to the illegal levels of BTLs, but provides a much more intense experience.
A Step by Step Guide to Hacking a System:
1.Detect the Wireless Network [SR4 p225]: Unless connecting directly to a node, a hacker must first locate its wireless connection.
2.Break In [SR4 p221]: This can be done over a period of time or on the fly. Once in a hacker should still be alert for roving security hackers and Intrusion Countermeasures (IC). In addition if an alert has been raised the system is likely to take active measures to deal with him.
3.Perform Tasks: Once a hacker is into the system he is free to go about performing any tasks that his account privileges would normally permit. Unauthorised operations will require a Test
4.Log Off [SR4 p220]: No test is required to log off; it is merely a Simple Action. The exception is when a hacker is engaged with Black IC in which case it may prevent him logging off [SR4 p231].
Intruder Alerts [SR4 p222]: An alert may be triggered by the system making a successful Analyze + Firewall test when the hacker breaks in. In addition patrolling security hackers or IC may raise an alert if they elect to scan the hacker and succeed on an Analyze + Computer (hacker’s Stealth) Test for hackers [SR4 p226] or Analyze + Pilot (hacker’s Stealth) Test for IC [SR4 p228].
A node on alert receives a Firewall bonus of +4 against the intruder that triggered the alert, this applies to all tests made by or against the node’s Firewall. Security hackers are alerted and may investigate.
In addition, when an alert is triggered a system will respond in one of the following ways (GMs call):
Launch IC Program [SR4 p223]: The GM decides what IC is launched to attack or track the hacker.
Terminate Connection [SR4 p223]: The system can try to sever the connection the hacker has made with it. This requires the system to win a System + Firewall versus the hacker’s Hacking + Exploit Opposed Test. If the hacker used a genuine account to log in the Exploit program does not apply.
System Reset [SR4 p223]: As a last resort the system can reboot which severs all connections to it in the process. Rebooting takes a System + Response (10, 1 Combat Turn) Extended Test. Anyone accessing the node when it shuts down is logged off ; all active programs are saved and shut down.
Intrusion Countermeasures (IC) [SR4 p228]: Intrusion Countermeasures are semi-autonomous programs capable of using other programs (e.g. Analyze, Attack and Track). IC programs have a Pilot attribute that acts as its Firewall attribute and used as its Computer, Hacking & Cybercombat skills.
IC runs on the computer node in which it is active and therefore uses the Response attribute of that node (nodes are careful not to run so many IC programs at once that it affects their performance.

Common System Operations
Anyone can use a commlink to perform basic tasks and searches, only hackers and professional users need the Computer, Data Search, Electronic Warfare and Hacking skills.

Breaking In – On the Fly [SR4 p221]
Hacking + Exploit (target’s Firewall, 1 Initiative Pass)
A hacker can hack a node on the fly obtaining Personal account privileges, increase the threshold by +3 for Security, or +6 for Admin privileges. Each time the hacker performs a test the system gets to make an Analyze + Firewall (hacker’s Stealth) Extended Test, if it succeeds an alert is triggered (see below).
Breaking In - Probing [SR4 p221]
Hacking + Exploit (target’s System + Firewall, 1 hour or 1 day)
Ideally a hacker will probe a target node’s weakness over a period of time looking for a way in, the Extended Test interval is 1 hour if in VR, 1 day if in AR. This will provide Personal account privileges, increase the threshold by +3 for Security, or +6 for Admin privileges.
Once the threshold has been achieved a hacker can break in with a simple Complex Action (no test required). However at this time the system gets to make an Analyze + Firewall (hacker’s Stealth) Test, if it succeeds an alert is triggered.
Control Device [SR4 p220]
Computer + Command
Control a device that you have accessed. Very simple tasks do not require a test (e.g. unlocking a door), otherwise a Test is required. Some tasks may require an appropriate skill to be used e.g. Mechanic + Command to repair a car using a repair drone.
Data Search [SR4 p219]
Data Search + Browse (2 to 16, 1 Initiative Pass to 1 Minute)
A data search allows you to find any piece of data you want (assuming it is available). An Extended Test is required with the Threshold and Interval determined by the difficulty & scope of the search.
Difficulty Easy: 2, Average: 4, Hard: 8, Extreme: 16.
Scope Same device: 1 Initiative Pass, Same network: 1 Combat Turn, Entire Matrix: 1 Minute.
Decrypt Signal / Data [SR4 p225]
Response + Decrypt (Encryption rating x 2, 1 Combat Turn)
Decryption of a wireless signal or data requires only a Simple action with the proper decryption key. Without the key an Extended Test is required.
Detect Wireless Node [SR4 p225]
Electronic Warfare + Scan (variable, 1 Combat Turn)
Locating an Active or Passive wireless network within range requires no test and takes only a Free action. If in an area of high wireless traffic the GM may require an Electronic Warfare + Scan (GM determined threshold, 1 Combat Turn) Extended Test.
If the target network is in Hidden mode an Electronic Warfare + Scan (4) Test is required. If looking for hidden nodes in general an Electronic Warfare + Scan (15+, 1 Combat Turn) Extended Test is required.
Edit [SR4 p218 & p225]
Computer + Edit or Hacking + Edit for unauthorised edits
Create, change, or erase a file, or alter the output of a device you have previously taken control of. Minor changes take a Complex action; extensive changes require longer and / or Extended Tests.
Intercept Traffic [SR4 p224]
Hacking + Sniffer
Intercept traffic passing through a wired medium e.g. a landline to landline comm call (one of the nodes it is passing through must be accessed),. The hits achieved becomes the Threshold for the tapped party to spot the tap with a Matrix Perception Test.
Intercepted communications can be copied / recorded automatically. The communication can be edited (see Edit above), however if the edits are to appear as if they originated from one of the parties you must succeed in a Sniffer + Hacking versus Firewall + System Opposed Test.
Intercept Wireless Signal [SR4 p225]
Electronic Warfare + Sniffer (3)
Intercept traffic passing through a wireless medium. There is no way to detect interception of a wireless signal. Intercepted signals can be copied / recorded automatically and edited with an Edit Test. If the wireless communication is encrypted, it must be decrypted before being able to intercept it.
Matrix Perception [SR4 p217]
Computer + Analyze
Make Perception Tests in the Matrix. Each net hit reveals one piece of information, for example type, rating, alert status, or any other pertinent information. (e,g. whether a file has been edited).
If your target is hiding a Computer + Analyze versus Hacking or Firewall + Stealth Opposed Test is required. As a rule, anything running a Stealth program is considered to be hiding.
Redirect Trace [SR4 p224]
Hacking + Spoof versus Computer or System + Track
A Redirect Trace requires an opposed test against the person or node attempting the track. Each net hit adds 1 to the Track Test’s Threshold (see Track below).
Spoof Command [SR4 p224]
Hacking + Spoof versus Pilot + Firewall
Transmit forged instructions to an agent or drone controlled by another user, against whom a successful Matrix Perception Test has been made to gain its access ID. A Complex action is required [SR4 p239].
Track [SR4 p219]
Computer + Track – Target’s Stealth (10*, 1 Initiative Pass)
You can trace the datatrail of a user you have previously detected with a Complex action. If the originating node is wired to the Matrix you identify the physical location. If the node is a mobile wireless device, the device’s physical location is triangulated to within 50 metres.
* +1 per hit on target’s Redirect Trace action, –2 if the target’s connection is jammed open by Black IC
Transfer Data [SR4 p219]
Computer + Edit (only if GM desires)
You can transmit, receive, upload and download data from one node to another with a Simple action.
Matrix Initiative [SR4 p230]: Matrix initiative is determined as follows:
Initiative Passes
Augmented Reality
As physical Initiative
As physical Initiative Passes
Virtual Reality (Cold Sim)
Commlink Response + Intuition
Virtual Reality (Hot Sim)
Commlink Response + Intuition + 1
Agents, Drones, Sprites & IC
Pilot + Response
Matrix Attacks [SR4 p230]: Cybercombat requires a Complex action and uses programs like Attack and Black Hammer to attack.
Attacker Rolls [SR4 p230]: Cybercombat / Pilot + Program rating
Defender Rolls [SR4 p230]: Response + Firewall (+ Hacking / Pilot if using Full Defence)
If the attacker gets more hits than the defender he has hit and inflicts damage. A tie indicates that the attack made contact but did no damage.
Modify DV [SR4 p140]: Program rating + Attacker’s net Hits
Damage Resistance [SR4 p231]: System + Armour (if damage is directed at the Icon)
Willpower + Biofeedback Filter (if damage is directed at Hacker)
Each Hit on the Damage Resistance Test reduces the modified DV by 1. The remaining DV is applied as boxes of damage to the appropriate Damage Track (the Icon’s or the Stun or Physical Track of the Hacker).
Dump Shock [SR4 p231]: When a hacker is dumped from the Virtual Reality Matrix (e.g. when his Icon crashes due to taking damage that fills its Damage Track) he suffers system shock.
Damage Value[SR4 p231]: 5 (Stun for Cold Sim, Physical for Hot Sim)
Damage Resistance [SR4 p231]: Willpower + Biofeedback Filter
In addition to any Damage a character suffering from dump shock suffers a -2 dice pool penalty to all actions for (10 – Willpower) minutes.

Rigging & Drones
Controlling Drones [SR4 p238]: In order to control a drone or vehicle via wireless communication it must be an active subscriber [SR4 p212]. Multiple drones can be subscribed as a single device, but all must be given the same orders. A drone can be issued a command and unsubscribed to carry out its instructions by itself. Drones can subscribe to each other to co-ordinate actions and share data.
Drones acting on their own use their Pilot and autosoft [SR4 p239] ratings for all necessary tests, and act on their own Initiative (Pilot + Response with 3 Initiative Passes).
Rigger Perception [SR4 p239]: When observing through a drone, a hacker rolls Sensor + Perception (rather than Intuition + Perception). Drones operating on their own roll Sensor + Clearsight autosoft.
Jumping Into Drones [SR4 p239]: A hacker may control a drone via full VR (taking a Complex Action to “jump into” the drone); this is known as rigging. The drone acts on the hacker’s Initiative and uses the hacker’s skills and attributes. A rigger who has jumped into a drone can still issue commands to other drones.
If the hacker is using Hot Sim he may suffer damage whenever the drone does. If the drone is destroyed the hacker is dumped from the Matrix and suffers Dump Shock.
Damage Value[SR4 p231]: Half the Damage the Drone suffered
Damage Resistance [SR4 p231]: Willpower + Biofeedback Filter
Rigging Action [SR4 p239]: A number of additional actions are available to hackers rigging drones.
Free Actions
Simple Action
Complex Actions
Activate / Deactivate Sensors
Actively Subscribe a Drone
Fire a Weapon System
Activate / Deactivate ECCM
Issue Command
Jam Signal
Arm / Disarm a Weapon System
Jump into / Leave a Drone
Spoof Command
Call Up a Status Report
Observe in Detail

Jamming [SR4 p225]: Jammers come in two varieties: area jammers 9jamming all wireless comms in range) and spot jammers (narrow angle jamming of specific frequencies). Initiating jamming is a Complex Action. Any device with a Signal + ECCM rating less than the jamming device’s Signal rating is overwhelmed.
