Subset Games, meaning Justin Ma and Matthew Davis, shipped this on 14 September 2012 after a Kickstarter that asked for 10,000 dollars and collected roughly twenty times that. You run a Federation ship through eight sectors with a Rebel fleet closing behind you, spending scrap on systems and weapons, and the run ends against a three phase Rebel Flagship in Sector 8. The free Advanced Edition update in April 2014 added the Lanius, hacking, mind control, the Clone Bay and the Backup Battery, and it is on by default now. Nothing is randomised in your favour, and a good run is mostly a sequence of decisions about what not to buy.
This guide covers everything you need: core mechanics, the best builds, equipment worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
Reactor power split across systems
Every system needs reactor bars and you never have enough. Shields cost two bars per layer, so a third shield layer is six bars sitting there permanently, and that trade against a fourth weapon or a Cloaking system is the central decision of every run.
Active pausing during combat
Space pauses everything and you can still issue orders, target rooms, move crew and change power allocation. Playing without using it is possible but the difference in outcome is enormous, since manually staggering weapon volleys so they land together is only practical while paused.
Crew skills and boarding
Crew improve at whatever station they man, and each of the eight species has a hard rule attached: Engi repair at double speed and take half damage in melee, Rockmen carry 150 percent health and ignore fire, Zoltan supply one free power bar to whichever room they stand in, Lanius drain the air out of rooms they occupy.
Fuel, scrap and the advancing rebel fleet
Every jump costs one fuel and advances the rebel fleet behind you, so the map is a race rather than a tour. Scrap is simultaneously your currency and your upgrade material, which means buying a weapon is always also a decision not to buy a shield layer.
The three phase Rebel Flagship
Sector 8 ends against a Flagship with four weapon mounts, a boarding drone, and three separate phases that repair between fights. It is the one fight in the game you can prepare for precisely, because its loadout never changes: expect a triple missile launcher, an ion weapon and a beam.

Equipment Guide
| Equipment | Why It Matters | Best For |
|---|---|---|
| Burst Laser Mark II | Two power, three shots, twelve second cooldown, and the single most recommended weapon in the game. | Any ship at any point in a run, and the backbone of every laser stack build |
| Halberd Beam | Three power, seventeen second cooldown, two damage per room, and unusually it pierces one shield layer, so it still lands one damage per room through a single barrier. | Pairing with lasers or ion weapons that drop the enemy to one shield layer or fewer |
| Flak Gun Mark I | Two power, three projectiles, ten second cooldown, and no ammunition cost. | Feeding a beam weapon by clearing shield layers on a short cycle |
| Glaive Beam | Four power, twenty five second cooldown, three damage per room and it pierces two shield layers. | Late run ships with high evasion and a Cloaking system to cover the long charge |
| Ion Blast Mark II | The fastest cycling ion weapon available. | Locking down enemy shields so beams, drones or boarders can work unopposed |
Burst Laser Mark II: Two power, three shots, twelve second cooldown, and the single most recommended weapon in the game. Three shots strip three shield layers on their own, or strip two and land a hull hit, which is why players build entire runs around finding a second one.
Halberd Beam: Three power, seventeen second cooldown, two damage per room, and unusually it pierces one shield layer, so it still lands one damage per room through a single barrier. On a typical ship layout it crosses at least three rooms per sweep for six damage from one shot.
Flak Gun Mark I: Two power, three projectiles, ten second cooldown, and no ammunition cost. It trades accuracy for cycle speed, and because each fragment that connects removes a shield layer it is the cheapest reliable shield stripper in the game.
Glaive Beam: Four power, twenty five second cooldown, three damage per room and it pierces two shield layers. It is powerful enough that you build the ship around it rather than the other way round, since four power in one slot leaves very little for anything else.
Ion Blast Mark II: The fastest cycling ion weapon available. Ion damage reduces a system's power temporarily rather than harming the hull, so it never starts fires or hurts crew, and a single Ion Blast Mark II held on the enemy shield room keeps it offline indefinitely.

Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Civilian Sector | Sectors 1 to 3 | Stores, low risk events, fuel and drone parts |
| Nebula Sector | Any sector, most useful when you need time | Slower rebel pursuit, hidden beacons, ion storm hazards |
| Mantis Homeworlds | Sectors 3 to 6 | High scrap rewards, Mantis crew recruits, heavy boarding risk |
| Abandoned Sector | Sectors 3 to 6, Advanced Edition only | Lanius crew, derelict salvage, unusual system rewards |
| The Last Stand | Sector 8, final | Run completion, ship unlocks, achievement progress |
Civilian Sector: The safest sector type on the map, with more shops, more stores and fewer forced fights than anything else. Take one early while your ship is still weak, and take a hostile sector instead once your loadout has come together and you need scrap rather than safety.
Nebula Sector: Sensors do not work, the rebel fleet advances more slowly, and ion storms cut your reactor output in half inside affected beacons. Slug crew see through the fog, which is the one reason a Slug in the crew roster matters more here than anywhere else.
Mantis Homeworlds: The most dangerous species sector in the game because Mantis ships board aggressively and Mantis crew win most melee fights. Bring a Medbay you can retreat to, and consider venting rooms rather than fighting boarders directly.
Abandoned Sector: Added by the Advanced Edition update along with the Lanius themselves. The sector runs on derelict stations and Lanius encounters, and Lanius crew drain the air from any room they stand in, which means fights here take place in vacuum more often than not.
The Last Stand: Sector 8, where the run ends. You get a short window to repair and buy at the Federation base before the Rebel Flagship arrives, and the fight runs across three separate phases with the Flagship repairing between them. Its loadout is fixed, so it is the only encounter you can plan for exactly.

Tips That Actually Matter
- Pause and stagger. Charging three weapons and firing them in one instant strips three shield layers at once, where firing them as they finish charging lets shields regenerate between shots.
- Buy the second shield layer before a third weapon, every time. Two layers stop most sector one to three enemies outright, and the scrap saved on repairs pays for the weapon later.
- The Rebel Flagship has a fixed loadout with four weapon mounts across three phases. Plan for its triple missile launcher specifically, since that is what kills unprepared ships.
- Blue option events are the free scrap of FTL. Carrying a Slug, having a Medbay upgraded, or owning a specific system unlocks them, and they almost always resolve better than the default choice.
- Halberd Beam pierces one shield layer and Glaive Beam pierces two. Every other beam in the game is stopped completely by a single layer, so pairing them with a shield stripper is mandatory.
- Sell missile weapons you cannot supply. An Artemis Missile with no ammunition is dead weight in a slot that a Flak Gun Mark I would use better.
- Boarding is the highest scrap strategy in the game because killing the crew leaves the hull intact for a larger reward. Disable the enemy Medbay first or your boarders will fight the same crew forever.
- Zoltan crew supply one power bar to whichever room they occupy. Moving one from Engines to Weapons mid fight is a free reactor upgrade that costs nothing but a few seconds of walking.
- Take Civilian sectors early and hostile sectors late. Your ship in sector two cannot absorb the fights that your ship in sector five will want for the scrap.
- Fuel is the one resource that ends runs silently. If you drop below four fuel with no store in reach, start taking distress beacons even when the risk looks bad.
Common Mistakes to Avoid
- Playing unpaused because it feels more skilful. Every strong player pauses constantly, and unstaggered weapon volleys are the single most common reason a run stalls in sector four.
- Upgrading Weapons power to run four weapons while still sitting on one shield layer, which turns every fight into a race you lose the moment a missile lands.
- Boarding a ship without disabling its Medbay, so the enemy crew heal faster than two Mantis can kill them and you lose boarders for nothing.
- Hoarding scrap for a store that never appears. Scrap in your pocket at the Flagship is worthless, so spend it by the end of sector six.
- Jumping into Sector 8 with a Glaive Beam and no Cloaking system, then discovering the twenty five second charge never completes against a Flagship that fires continuously.
Frequently Asked Questions
What is the best starting ship in FTL?
The Kestrel Cruiser Type A is the most forgiving, since it opens with a Burst Laser Mark II, Artemis Missiles and three crew with no gimmick to manage. The Mantis Cruiser is stronger in the hands of someone who already understands boarding, because captured ships pay more scrap than destroyed ones.
Which weapons should I always buy?
Burst Laser Mark II, Flak Gun Mark I and Halberd Beam, in roughly that order. The first two strip shields cheaply, the Halberd pierces one shield layer and hits two damage per room across a whole sweep, and together they cover both halves of almost every fight.
How do I beat the Rebel Flagship?
Arrive with three shield layers, a way to stop its missiles such as Cloaking or Defence Drones, and enough burst damage to break a phase before it repairs. The loadout never changes across the three phases, so the fight rewards preparation more than reaction.
Is Advanced Edition worth turning on?
It is free, it is on by default, and it added the Lanius, Hacking, Mind Control, the Clone Bay, the Backup Battery and the Abandoned Sector. The only argument for switching it off is that the extra systems make an already tight scrap budget tighter.
Why do I keep running out of fuel?
Every jump costs one fuel and there is no way to generate it without events or stores. If you are burning jumps exploring rather than moving toward the exit beacon, you will hit sector four with two fuel and no store, which is how most fuel deaths actually happen.
