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 walkthrough takes you from your first session to endgame content. Each phase has specific goals, priorities, and milestones. New to the game? Start with our beginner's guide first.
Quick Progression Summary
| Phase | Area | Focus | Build | Duration |
|---|---|---|---|---|
| 1. Start | Civilian Sector | Reactor power split across systems basics | Engi Cruiser | 1-2 hours |
| 2. Early | Nebula Sector | Active pausing during combat mastery | Engi Cruiser | 3-5 hours |
| 3. Mid | Mantis Homeworlds | Crew skills and boarding + gear | Kestrel Cruiser or Engi Cruiser | 5-10 hours |
| 4. Late | Abandoned Sector | Build optimization | Kestrel Cruiser | 5-10 hours |
| 5. Endgame | The Last Stand | Min-max | Kestrel Cruiser or Zoltan Cruiser | Ongoing |
See our maps guide for detailed area breakdowns.
Phase 1: Getting Started (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.
Level/Difficulty: Sectors 1 to 3 Key Rewards: Stores, low risk events, fuel and drone parts
What to Do in Civilian Sector
- Learn Reactor power split across systems. Every system needs reactor bars and you never have enough. Spend your first session getting comfortable with this.
- Pick Engi Cruiser as your starting build. See our builds guide for why.
- 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.
- Acquire your first equipment upgrade: Halberd Beam or whatever's available.
- Clear all main content before moving on.
Phase 1 Checklist
- Understand Reactor power split across systems fundamentals
- Engi Cruiser selected and functional
- Civilian Sector main content cleared
- Ready for Nebula Sector
Phase 2: Early Game (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.
Level/Difficulty: Any sector, most useful when you need time Key Rewards: Slower rebel pursuit, hidden beacons, ion storm hazards
What to Do in Nebula Sector
- Work on Active pausing during combat. Space pauses everything and you can still issue orders, target rooms, move crew and change power allocation. This system becomes critical from here on.
- Farm for Halberd Beam if you haven't already. It's the key upgrade for this phase.
- 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.
- Complete all objectives before pushing to Mantis Homeworlds.
- Consider whether Kestrel Cruiser might suit your playstyle better than Engi Cruiser.
Phase 2 Checklist
- Active pausing during combat integrated into gameplay
- Halberd Beam acquired
- Nebula Sector fully cleared
- Ready for Mantis Homeworlds
Phase 3: Mid Game (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.
Level/Difficulty: Sectors 3 to 6 Key Rewards: High scrap rewards, Mantis crew recruits, heavy boarding risk
What to Do in Mantis Homeworlds
- Master 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. This unlocks a new layer of gameplay.
- Start working toward Burst Laser Mark II. It's the best equipment and becomes accessible around now.
- 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.
- This area is the main skill check. If you can clear it, you're ready for late game.
- Start investing in Fuel, scrap and the advancing rebel fleet for the tactical depth you'll need going forward.
Phase 3 Checklist
- Crew skills and boarding mastered
- Burst Laser Mark II acquired or in progress
- Mantis Homeworlds fully cleared
- Ready for Abandoned Sector
Phase 4: Late Game (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.
Level/Difficulty: Sectors 3 to 6, Advanced Edition only Key Rewards: Lanius crew, derelict salvage, unusual system rewards
What to Do in Abandoned Sector
- Finalize your build. You should be running Kestrel Cruiser or Engi Cruiser with optimized gear.
- Burst Laser Mark II should be your primary. If you don't have it yet, prioritize getting it.
- 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.
- The three phase Rebel Flagship optimization starts here. Small improvements compound into massive advantages.
- Farm this area for the resources needed to push into The Last Stand.
Phase 4 Checklist
- Build fully optimized
- Burst Laser Mark II upgraded to max
- Abandoned Sector fully cleared
- Ready for The Last Stand
Phase 5: Endgame (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.
Level/Difficulty: Sector 8, final Key Rewards: Run completion, ship unlocks, achievement progress
What to Do in The Last Stand
- The Last Stand tests everything. Come prepared with your best build and gear.
- 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.
- The endgame loop: run The Last Stand, optimize gear, push harder content.
- Experiment with Zoltan Cruiser for a fresh take once you've mastered the standard builds.
- This is where The three phase Rebel Flagship mastery separates good players from great ones. See our tips guide for advanced strategies.
Phase 5 Checklist
- Endgame content on farm
- Best-in-slot gear acquired
- The Last Stand fully cleared
- Ready for challenge content
Common Progression Mistakes
- 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.
Key Tips for Smooth Progression
- 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.
