Tactical Starship Rules
The key difference between a tactical starship encounter and a typical combat encounter is that starship encounters take place on board the players’ starship; they use a starship map depicting the parts of their starship as well as a sensor map displaying other starships and hazards in the vicinity. When acting as crew members during a tactical starship encounter, PCs can use most of their abilities as normal, but if they want to interact with starship-scale objects on the sensor map, they’ll need to helm a battle station (such as gunnery or scanners). Starship stations grant special actions that can only be used while helming that station, but a crew member isn’t confined to a single station. A crew member might begin combat at a gunnery station, then move to the engine room to fight off boarders or fix a malfunction, then return to the gunnery station to finish off an enemy starship. Meanwhile, another crew member might spend the whole time at the pilot’s console performing desperate maneuvers to evade enemy fire!
A character-scale combat encounter might take place on board the player starship—such as if a rampaging garaggakal phases through the hull and begins stalking the crew. The starship’s battle stations won’t have any effect against the garaggakal, and a sensor map would be useless to track its movement. To change this scene to a tactical starship encounter, the same combat with the garaggakal might occur during a deep space skirmish with Aeon Guard starships, or the garaggakal’s presence might alert a nearby Hellknight patrol sworn to purge the monster at all costs—even if it means battling the crew trying to contain it!
What You'll Need
- A starship sheet with details about the crew's starship, its customizations, and its statistics.
- A starship map depicting the player starship, such as a Starfinder Flip-Mat, a custom map from an adventure, or a map of your own creation.
- A sensor map that's easily visible to the GM and all players.
- A list of the station actions granted by the battle stations on the player starship.
- Statistics for one or more enemy starships or starship hazards
- Familiarity with the new rules for tactical starship combat, such as new conditions, terms, and traits.
Starship Sheet
A player starship sheet has a similar structure to player character sheets. It lists the starship’s Hull Points, Shield Points, AC, Speed, sensor range, size, traits, and saving throw modifiers. Many of these statistics are derived from the starship frame chosen. The starship’s AC and saving throws can improve when crew members helm certain battle stations on the ship.
The starship sheet lists the number of expansion bays available on the player starship. An expansion bay is a room or deck that can house facilities such as a medical bay or leisure spaces like a holo den, which can facilitate certain downtime activities or give other boons. These facilities are listed on the sheet, along with the benefits they provide. You can find the list of expansion bays.
The starship sheet also lists the starship’s battle stations and other equipment like weapons and upgrades.
You can find a blank starship sheet in the back of this book or on paizo.com as a free PDF. While you might have one player or the GM handle the work of tracking and updating the starship’s statistics, it’s a good idea to keep a copy of the crew’s starship sheet for each player as well as for the GM so everyone knows the most up-to-date statistics, options, and other important information about the ship’s capabilities during tactical starship combat.
Starship Map
Every crew should create a starship map indicating the position of each battle station. Each crew member typically begins starship combat helming a battle station, as determined by their exploration activity. Battle stations enable crew members to affect distant enemies detected by the starship's sensors, but sometimes, enemies board a player starship, or hazards appear on deck to represent malfunctions and other dangers. A map is essential for tracking encounters between the crew and boarding enemies or deck hazards. A player can spend every turn helming one battle station, or they can switch to another battle station during the encounter. Reasons to switch battle stations include needing a new approach against a tough enemy, not having the means to repair your malfunctioning battle station, stepping in for a teammate who goes down, or simply wanting to change things up.
Creatures and hazards might appear on the player starship. During an invasion or malfunction, the crew might choose to leave their battle stations to deal with these threats or ignore the problem until the threat comes to them. If left alone for too long, these threats can cascade into greater problems as invaders wreak havoc in an engine room or a hull breach begins to suck more and more air out from the starship's interior.
The players and the GM need to work together to build a wonderful home for the crew.

Once activated, a minibot has the minion trait. It obeys you to the best of its ability when you use an action to Command it. You must be within 60 feet to verbally command a minibot.
Battle Stations
A battle station can be enhanced similar to any other equipment and gains benefits depending on its grade, including the ability to equip it with station upgrades. These upgrades often grant additional abilities beyond the basic functions of a battle station. With access to many types of battle stations and station upgrades, a party of adventurers can customize their ship to their liking, making the starship into something that's especially suited to their capabilities.
Many station actions are similar to actions a character can use in combat; for example, you can Strike using the weapons in your starship's gunnery, firing its weapons against targets within range. Many character abilities interact with battle station actions; as a new example, an operative can use the Aim action to pierce cover from an asteroid and add precision damage to their gunnery Strikes against their mark. In such cases, these actions can be used in tactical starship combat the same way they can be used in regular combat. In this example, the operative can Aim a gunnery station's weapons to enhance their damage against that target, but Aim otherwise functions as usual. Or, if the gunnery has an automatic weapon equipped, a soldier can use their primary target ability to make an additional Strike against their primary target when they Auto-Fire with the gunnery.
Most station actions require a creature to helm a battle station, meaning the creature is in the battle station's square, usually an apparatus or console, and is using it.
Enemy Starships And Hazards
Some tactical starship combat encounters involve creatures or hazards that appear on board the crew's starship while they're fighting enemies on their sensor map. GMs can find plenty of monsters and NPCs in Alien Core, published adventures, and other Starfinder books or create their own using the guidelines in GM Core. Some of the hazards appear on the starship map rather than the sensor map and affect characters directly. Many hazards presented in GM Core work well in starship combat.
Starship Combat Structure
Step 1: Roll initiative. The process of rolling initiative is the same as any other encounter, but crew members can choose to roll a skill associated with the battle station they're helming.
The player starship doesn't roll its own initiative, as its actions are determined by the crew, but enemy starships and hazards always roll initiative.
Step 2: Play a round. Each crew member gets three actions to use on their turn. Turns are typically spent on taking station actions and moving between stations, but if a battle station malfunctions or a boarding pod hits the hull, characters have to make some tough choices about how to use their actions!
Step 3: Begin the next round. Similar to any other combat encounter, combat continues in rounds until the GM determines the encounter has ended. Typically, this occurs when all enemy starships are defeated and all hazards are disabled, or when the player starship has been defeated.
Step 4: End the encounter. At the end of a tactical starship encounter, crew members earn experience for defeating foes and overcoming hazards just as they would for any other combat encounter. Tactical starship encounters don't necessarily need to continue until every enemy ship is destroyed; a pirate crew might surrender rather than see their ship scrapped, or a military scout might flee capture after taking heavy damage.
If the player starship is defeated instead, the GM might choose to have enemies send boarding parties, starting a new normal combat encounter.
New Rules
Helming Battle Stations
To helm a battle station, a crew member must occupy its square and must have at least one free hand. A crew member can't helm the battle station if they're unconscious or otherwise incapacitated. A crew member keeps helming the battle station until they're no longer occupying the battle station's square. Only one character can helm a battle station at a time.
A character helming a station gains access to the battle station's various station actions. Battle stations often grant one or two additional effects, such as allowing a character in the pilot's console to use their Piloting DC in place of the starship's AC. Battle stations upgraded to a higher grade often grant additional station actions and benefits.
Zones
Whether to maneuver to a different zone is often an important decision in tactical starship combat; the pilot must consider the crew’s capabilities as well as their enemies’ weapon ranges and the proximity of features that provide cover or hide environmental hazards. Some actions require a target to be in the same zone as the starship, and other actions can be used from great distances or have different effects depending on range. For example, if a player starship has a gunnery, the crew can catch another starship off-guard by getting behind them before firing.
Starship Movement
Heading
A starship is off-guard to attacks made from the opposite direction of the starship’s heading. Starships in the same zone always treat each other as being in the direction of their heading. Specific rules and actions might have different results depending on starships’ headings.

Hull Points
If it’s ever unclear whether an effect referencing HP is referring to Hit Points or Hull Points, check whether the effect has the starship trait, or originates from a starship or a starship hazard. Any such effect typically affects Hull Points rather than Hit Points.
Shield Points
Shield Points can’t be restored by effects that restore Hull Points, but they can be restored by other means, such as the Generate Shields action at the generator battle station. An effect can restore a starship’s Shield Points even if it has 0 Hull Points; restoring shields has no effect on a starship’s Hull Points or any other conditions resulting from hull damage, but in this case, the Shield Points might still protect the ship from taking enough damage to be destroyed (see Destroying Starships below).

Destroying Starships
Becoming Compromised
When a player starship is reduced to 0 Hull Points:
- The starship gains the compromised 1 condition. If the effect that reduced the starship to 0 Hull Points was a critical success from the attacker or the result of the starship's critical failure, the starship gains the compromised 2 condition instead. If the starship has the wrecked condition, increase its compromised value by an amount equal to its wrecked value. If the damage was dealt by a nonlethal attack or nonlethal effect, the ship doesn't gain the compromised condition; it's instead inoperable with 0 Hull Points.
A compromised starship is heavily damaged and difficult to operate. Compromised always includes a value; if this value reaches compromised 10, the ship is destroyed. While the ship is compromised, its compromised value can increase or decrease in three ways: hull integrity checks, taking damage, and ship repairs. - Each battle station on the starship gains the malfunctioning condition. This prevents most station actions from being used, though crew members can still move around the ship, fight boarders, and gain passive benefits (if any) from helming battle stations. Most importantly, they can conduct repairs to restore function to battle stations and stop the ship from being destroyed!
- Note the initiative count when the starship became compromised. The starship enters initiative, positioned directly before the turn in which it was reduced to 0 HP. This is when it must attempt hull integrity checks in subsequent rounds, as described below. It leaves initiative if it ever loses the compromised condition.

Exploration Activities
When you want to do something other than simply travel, you describe what you’re attempting to do. It isn’t necessary to go into extreme detail; you don’t need to say, “I activate the starship’s tactical-grade scanners and pinpoint the positions of all bogeys in zone 3,” for example. “I’m scanning for enemies” is sufficient.
New exploration activities are available to you while you’re traveling on board a starship. They often determine both where you are on the ship and what you can do if tactical starship combat breaks out. Many of the exploration activities available to your crew are determined by the battle stations on your starship.
These are the most common starship exploration activities.
Class Roles In Starship Combat
Any class can helm any battle station, and most excel at helming more than one. It's not uncommon for a character to switch stations as battlefields evolve and enemies begin using unforeseen tactics. This is especially true when confronting starship hazards like boarding pods that can completely change the dynamics of an encounter. Crew members can find new and exciting ways to utilize their class abilities while fighting a tactical starship battle. For example, an envoy who leads from the front can use Into Position! to rush the crew to their battle stations when the starship is unexpectedly ambushed.
Naturally, any spellcaster excels when helming the magic conduit station, and when upgrading the crew's starship, they should install upgrades that are built for their class. Spellcasters should familiarize themselves with the starship's spell repository. The spells give options for dealing damage as well as for restoring Hull Points and Shield Points. Even if a spellcaster runs out of spell slots, they're likely to be as competent as any other character at most battle stations.
Envoy
An envoy with Get In There! can also help their entire crew reposition in the case of an enemy boarding their starship or if one of their crewmates needs help switching battle stations.

Example Of Starship Combat
Obozaya (Mike): “Time to Lock and Load.” I'm counting our ammunition in the gunnery.
Chk Chk (Dustin): “Let's see what secrets the void holds.” I'm Scanning for Magic. Do I feel anything through the magic conduit? Scan for Magic allows a character to detect the presence or absence of magic within the starship's sensor range much like the spell detect magic.
Aras: Nothing—for now, at least. Iseph (Jessica): I'm Flying the Ship. As always. I want to Boost Thrusters to get the starship away from all the rocks floating out here.
Navasi (Jenny): Chk Chk has magic covered, so I'll Scan our Surroundings for everything else. There's a hazard on the sensor map, so Aras rolls a secret check for Navasi to notice it. She fails to notice the tachyon burst, but it isn't the only danger.
Aras: The sensors ping, and a surge of divine rage blasts the magic conduit. A massive, purple vessel looms in the sensors. It's an ambush—roll for initiative!
Aras reveals the sensor map, placing an Azlanti Sovereign Dominator four zones behind the player starship. Everyone rolls Perception for their initiative. Jessica gets a total of 22. Jenny rolls 16, Mike rolls 10, and Dustin gets 14. Aras rolls for the Dominator and gets a 21, then records the initiative order from highest to lowest. Thanks to their choice of exploration activities, everyone but Chk Chk can take a special free action when they roll initiative. Since she was Locking and Loading, Obozaya can Lock On to the Dominator to get a bonus on her first attack. Iseph gets to Evade, granting their starship a +1 circumstance bonus to its AC until their first turn. Navasi can Scan Target, attempting a Computers check against the Dominator's Will DC. Jenny rolls a 26. The Sovereign Dominator has a Will DC of 27. The Scan Target fails, so Navasi still learns about the Dominator's model name and its battle stations—a generator, a gunnery, a pilot's console, and scanners—but she can identify only one of the battle stations, allowing the crew to target it with other actions later to potentially cause it to become malfunctioning.
Navasi (Jenny): I'll identify the gunnery. “Obo, try to take out their guns!” Aras: That'll have to wait—Iseph's up first.
Iseph (Jessica): Got it. I'll Change Heading with my first action, then Juke with my second.
Jessica rolls a 28 total on her Piloting check to Juke, which beats the Dominator's Perception DC of 27. With a success, the Dominator is off-guard to the player starship for 1 round.
Iseph (Jessica): “We've got them right where we want them.” I'll use my third action to Evade again.
Aras: You'll need that AC bonus—it's the Azlanti starship's turn. It Boosts Thrusters to get you in range, then hits you with a beam of amethyst energy. Someone roll a Will save!
Mike rolls a 9 and adds the starship's Will modifier of +12, for a total of 21—a failure against the Dominator's Lissala's Eye save DC of 23. With that failure, the player starship is now off-guard to all attacks from Azlanti starships for 1 round.
Aras: Finally, the enemy starship fires on you with a bolt of electricity.
Aras rolls a 34 for the Dominator's Strike, which is a critical hit on the starship's AC of 24 for a whopping 35 electricity damage. The player starship's 20 Shield Points are taken out instantly, and the remaining 15 damage is dealt to its Hull Points. The electrical discharge also triggers the tachyon burst hazard. The starship critically fails this time, causing the generator to become malfunctioning.
Navasi (Jenny): “I'd better fix that if we want to get our shields back online!” I Stride from the scanners to the generator, and I rolled a 17 on my Computers check to repair it.
Navasi needs to helm the generator to repair it, so she must Stride twice to reach its location on the starship map. The DC to repair a malfunctioning battle station is 15, so her 17 succeeds.
Aras: The generator buzzes back to life. You can use it to Generate Shields next turn. Chk Chk, you're up.
Chk Chk (Dustin): “Embrace the pain. I'll hold us together for now.” I use a 1st-rank spell slot to cast cosmic fortification from the magic conduit, then a 3rd-rank slot for cosmic bombardment to return fire.
Chk Chk can cast starship spells using his own spell slots while helming the magic conduit. Cosmic fortification restores a total of 7 Shield Points to the starship, and cosmic bombardment deals a total of 16 force damage to the Sovereign Dominator without requiring any checks.
Aras: The barrage of divine missiles leaves the Azlanti ship's shields battered and barely intact.
Obozaya (Mike): “Time to finish the job!” I'll Target Battle Station—choosing the gunnery Navasi pointed out, obviously—then Area Fire with our farseeker missiles.
Since Navasi's Scan Target identified the Dominator's gunnery, Obozaya can target it. Thanks to Obozaya's primary target ability, she first Strikes the Dominator as a free action, rolling a 25—a hit! The Dominator takes a total of 17 piercing damage, tearing through the rest of its shields and taking 1 Hull Point damage. Since Obozaya used Target Battle Station and the Strike dealt Hull Point damage, the Dominator's gunnery is malfunctioning. The Dominator rolls a 21 on its Reflex save against the Area Fire—a failure—and takes another 10 piercing damage.
Aras: The mighty Azlanti warship looks seriously battered as your missiles explode all around it. Its shields and guns are both down—this ambush probably isn't going the way that crew had hoped! But what's that seven-sided portal materializing at the edge of your sensors? Uh oh, it looks like Azlanti reinforcements have arrived!
This marks the end of the first round of combat. The second round moves back to the top of the initiative order with Iseph's turn, ready to press their advantage before more foes show up. Now, it's your turn…
