Augmentations are items that passively provide benefits to your ship. Your ship can equip up to three of them; spare augmentations cannot be stored in the cargo hold. They can be bought at stores or rewarded from events.

Their benefits range from improving stats (FTL Recharge Booster) to granting entirely new abilities (Adv. FTL Navigation) and effects (Reverse Ion Field).

Most of the stat-boosting Augmentations stack with each other. The ones that don't stack are grayed out in stores if you already own one (or if all your augmentation slots are filled). If you loot an augment that you already own and does not stack, you receive 25 scrap instead (regardless of the augment value). If you loot an augment and don't have room for it, you must choose one augment to leave behind, and you do not earn the resale value.

Weapon Augmentations[]

Automated Re-loader[]

"Cooldown between weapon shots is improved by 10 percent."

  • This also applies to the artillery system on the Federation Cruisers
  • Stacks additively with multiple reloaders, and stacks multiplicatively with crew skill
  • Cost: 40 Ftlgame-scrap.png
  • Rarity: 2

The augment description is somewhat misleading. It actually increases firing rate by 10%. You could think of it as increasing shots per minute. Reloaders stack additively, so three of them increase firing rate by 30%. Cooldown is the inverse of firing rate, so one Automated Reloader divides cooldown by 1.1.

If "C" is the crew skill multiplier and "R" is the number of reloaders, the charge time multiplier is: C/(1 + R/10)

For example, with fully-trained crew and three reloaders, the multiplier is 0.8/(1 + 3/10) = 0.615, meaning a Flak 1 would fire in 6.15 seconds.

Weapon Pre-Igniter[]

"Weapons are made immediately available after an FTL jump."

  • Only works for weapons that were powered from the previous beacon.
  • Only skips the first charge cycle of chain weapons (so no "instant Vulcan")
  • Only gives one charge to charge weapons, by default. Can fully charge them using a trick.
  • Does not affect the artillery weapons found on the Federation Cruisers.
  • The most expensive augment in the game.
  • Cost: 120 Ftlgame-scrap.png
  • Rarity: 4

Stealth Weapons[]

"Prevents your weapon fire from disrupting your cloak, allowing you to shoot at will while cloaked."

  • This augmentation removes the cloak-shortening effect caused by firing non-beam weapons while cloaked.
  • Cost: 50 Ftlgame-scrap.png
  • Rarity: 3

Helpful with quick-firing weapons, if you want to fire during cloak. However, the augment also prevents intentionally breaking cloak, which can help your cloak recharge between Flagship power surges.

Explosive Replicator[]

"Missile based weapons have a 50 percent chance of not using a missile."

  • Multi-shot weapons (Swarm and the Pegasus Missiles) have the same 50 percent chance of not using a missile in their volley. This is because one missile is used when firing these weapons, even though there are multiple attacks from them.
  • Not stackable.
  • Cost: 60 Ftlgame-scrap.png
  • Rarity: 3
  • Advanced Edition only.

Hacking Stun[]

"All crew inside a room during a Hacking Pulse will be stunned for the duration."

  • Affects both the enemy's and player's crew members.
  • Crew members who enter the affected room during the Hacking Pulse are stunned to the end of the duration as well.
  • Cost: 60 Ftlgame-scrap.png
  • Rarity: 3
  • Advanced Edition only.

This augment is almost useless, since hacking already locks doors and impedes enemy crew movement.

Defense Scrambler[]

"Prevents enemy defense drones from targeting anything."

  • Causes defensive drones to completely stop working.
  • Does not affect the enemy Shield Overcharger.
  • Does not affect enemy combat drones or boarding drones.
  • The Engi Cruiser Layout C starts with this augment.
  • Cost: 80 Ftlgame-scrap.png
  • Rarity: 4
  • Advanced Edition only.

Defensive Augmentations[]

Shield Charge Booster[]

"Boosts the ship's shield recharge rate by 15 percent."

  • Stacks additively with multiple Shield Charge Boosters, and multiplicatively with crew skill
  • Cost: 45 Ftlgame-scrap.png
  • Rarity: 2
  • Useful when dealing with a lot of lasers, such as the drone assault in phase two of the flagship.

It's a 15% increase in recharge rate, not a 15% decrease in recharge time. Recharge time is the inverse of recharge rate. To find the improved time, divide by 1.15, giving about 87% of the base time (not 85%).

Shield Charge Boosters stack additively, so three of them give a 45% increase in recharge rate (dropping the recharge time to about 67%).

Reverse Ion Field[]

"Protects your ship from ion damage, giving a 50 percent chance to negate it entirely."

  • Stackable.
  • Immunity to ion damage with multiple.
  • Can protect from the ion pulse environmental hazard.
  • Cost: 45 Ftlgame-scrap.png
  • Rarity: 2

Repair Arm[]

"Repairs your hull every time you collect scrap, but reduces scrap collected by 15 percent."

  • Repairs your hull for 2 points every time you collect scrap.
  • The scrap reduction percentage rounds against you.
  • Not stackable.
  • Cost: 50 Ftlgame-scrap.png
  • Rarity: 3
  • Widely considered an undesirable augment, since the scrap loss might be significant. But it may find its use in between Flagship battles.

Emergency Respirators[]

"Crew take half damage from low oxygen."

  • Crystal crew members take only 25% damage from low oxygen with this augment.
  • Allows crew members to heal in a level 1 medbay without oxygen.
  • The effect also works when boarding enemy ships, allowing safer boarding of Lanius or Automated ships.
  • The Lanius Cruiser (Type A and Type B) start with this augment, as does the Federation Cruiser Type C.
  • Not stackable.
  • Cost: 50 Ftlgame-scrap.png
  • Rarity: 2
  • Advanced Edition only.

Fire Suppression[]

"Automatically put out fires throughout the ship."

  • Cost: 65 Ftlgame-scrap.png
  • Rarity: 3
  • Advanced Edition only.
  • Puts out all fires at once, slightly slower than a Human crew.

Backup DNA Bank[]

"Your crew is safe in clone storage even if the system is off or broken."

  • Has no effect with a Medbay.
  • Dead crew members will remain in the clone queue regardless of the state of the Clone Bay, allowing you to delay their cloning for as long as necessary.
  • Does not resurrect crew members who died before getting the augment or who died when a Clone Bay was not installed.
  • Discarding the augment while crew members are in the clone queue with the Clone Bay depowered will trigger the "Crew are dying" warning.
  • If all of your crew die and the Clone Bay is destroyed, there will be no-one to repair the Clone Bay (unless you are able to deploy a System Repair Drone or Repair Burst) and your crew will stay in the bank forever. The game over screen won't show, forcing you to restart manually.
  • Can be used in the Crystalline Research Facility event.
  • Cost: 40 Ftlgame-scrap.png
  • Rarity: 2
  • Advanced Edition only.

FTL Augmentations[]

FTL Recharge Booster[]

"The ship's FTL Drive powers up 25 percent faster."

  • Stackable.
  • Cost: 50 Ftlgame-scrap.png
  • Rarity: 2
  • The bonus works like Automated Reloaders. It's a 125% multiplier for the charge rate, not a 75% multiplier to the charge time; so charge time is multiplied by 80%.
  • The recharge boost from this augment is rather weak, so scrap is usually better spent on engines instead.

FTL Jammer[]

"Scramble enemy ships' FTL computers, doubling the time it takes for them to jump."

  • Not stackable.
  • Cost: 30 Ftlgame-scrap.png
  • Rarity: 3
  • Can be slightly useful for defensive setups, though the 30 scrap might be better spent on improving your offensive capabilities instead.

Adv. FTL Navigation[]

"Allows the ship to jump to any previously visited Beacon."

  • Not stackable.
  • This means you can go back to any 'blue' beacon in only one jump.
  • Can be used in the Civilian FTL Haywire Escort event.
  • Cost: 50 Ftlgame-scrap.png
  • Rarity: 3
  • Occasionally this lets you get extra beacons when "diving" past the exit. Otherwise, mostly useless providing you plan your route in advance.

Distraction Buoys[]

"Leaves a false signal at sector start to delay Rebels 1 jump."

  • Not stackable.
  • Only works at the beginning of a sector, so it's never useful right away.
  • Can be used in the Crystalline ship messaging about Rebels event.
  • Cost: 55 Ftlgame-scrap.png
  • Rarity: 3
  • Advanced Edition only.
  • Best to sell it by Sector 7 as its effects become pointless in the final sector. This augment is similar to Scrap Recovery Arm.

Misc. Augmentations[]

Long-Ranged Scanners[]

"Adds additional info about nearby Beacons on the star map."

  • Allows you to see if an adjacent beacon contains a ship or an environmental hazard before jumping to it.
  • If a beacon does not indicate a ship, it may still result in a ship fight. Likewise, even if a ship is detected, there may be ways to avoid a fight.
  • Is used in some events.
  • The Stealth Cruiser (All Layouts, A, B and C) starts with this augment.
  • Some quests will not be shown on the map with the scanner (Rebel Shipyard, Unarmed Zoltan Transport, and The Engi Fleet Discussion).
  • Cost: 30 Ftlgame-scrap.png
  • Rarity: 1
  • This augment is well worth purchasing. Finding more fights significantly increases scrap income, and seeing hazards is also useful.

Scrap Recovery Arm[]

"Allows the ship to collect 10 percent more scrap from any source."

  • It always rounds down, and extra arms stack additively (before rounding).
  • If you had the arm and got 19 scrap, you would get 1 extra scrap. If you had 2 arms, and got 15 scrap, you would get 3 extra scrap.
  • Provides a blue event option which involves mining an asteroid field.
  • Cost: 50 Ftlgame-scrap.png
  • Rarity: 1

This augment will almost always pay for itself, unless purchased very late. The scrap gains are considerable. However, the opportunity cost can also be high, especially when purchased early. Rarely a wise purchase on Hard.

Drone Recovery Arm[]

"Non-destroyed drones will be retrieved when jumping, allowing their parts to be reused."

  • Only recovers your own drones, not enemy drones.
  • Only recovers external drones. Does not recover Boarding Drones, Ion Intruders, or hacking drones.
  • Allows you to use multiple combat or defensive drones in every fight, without running out of parts.
  • Can be used together with Hull Repair Drone. The drone always repairs a minimum of 3 hull before vanishing, so jumping after 2 repairs makes those repairs always free.
  • Cost: 50 Ftlgame-scrap.png
  • Rarity: 2

Battery Charger[]

"Backup Battery's lock time is halved."

  • Not stackable.
  • Reduces the battery cooldown period to 10 seconds.
  • Cost: 40 Ftlgame-scrap.png
  • Rarity: 2
  • Advanced Edition only.

Zoltan Shield Bypass[]

"Allows crew/bomb teleportation and mind control to work through Zoltan Shields."

  • Can be useful when boarding, especially against the Rebel Flagship in phase 3.
  • Cost: 55 Ftlgame-scrap.png
  • Rarity: 3
  • Advanced Edition only.

Reconstructive Teleport[]

"Crew gets fully healed by teleportation."

  • More useful with a clone bay, allowing you to have full-health boarders without waiting multiple jumps or resurrecting them with loss of skill.
  • Will heal mind-controlled enemies.
  • Cost: 70 Ftlgame-scrap.png
  • Rarity: 3
  • Advanced Edition only.

Lifeform Scanner[]

"Detects the location of any life forms, even when sensors don't function."

  • Functions exactly like a slug crewman showing crew. You could just spend 45 scrap and outright buy a Slug crewman, however.
  • Can be used in some events.
  • Cost: 40 Ftlgame-scrap.png
  • Rarity: 3
  • Advanced Edition only.

Non-Purchasable Augmentations[]

Engi Med-bot Dispersal[]

"Engi nano med-bots heal the crew outside of the med-bay (at a reduced speed)."

  • Does not work if you have a Clone Bay instead of a Medbay.
  • Your Medbay must be powered.
  • Not affected by Medbay upgrades.
  • Used in some blue event options.
  • Not stackable.
  • The Torus (Engi Cruiser Layout A) starts with this augment.
  • Can be acquired by any ship through the Rebel attacking Engi event.
  • Cost: 60 Ftlgame-scrap.png
  • Heals 1.6 health points per second.
  • Does not work on crew that is on another ship (teleported).

Rock Plating[]

"Superior hull armor provides a 15 percent chance to negate incoming hull damage (hit systems will still be damaged)."

Titanium System Casing[]

"All ship systems have additional plating that provides a 15 percent chance to negate damage when hit (hull will still be damaged)"

  • The Nesasio (Stealth Cruiser Layout A) starts with this augment.
  • Can be acquired by any ship through the Stealth Cruiser unlock event, even if the Stealth Cruiser has already been unlocked.
  • Cost: 80 Ftlgame-scrap.png
  • This augment is essentially the counterpart to Rock Plating: instead of reducing hull damage, it reduces system damage.

Drone Reactor Booster[]

"Your shipboard drones have their movement speed increased by 25 percent."

  • The Vortex (Engi Cruiser Layout B) starts with this augment.
  • Can be acquired by any ship through the Engi Virus event.
  • Cost: 50 Ftlgame-scrap.png
  • A very negligible boost. It makes drones move from 50% the speed of most crew to 62.5% the speed of most crew. Selling it for 25 scrap is the recommended strategy.

Slug Repair Gel[]

"Slug ships excrete a thick gel that automatically repairs any hull breaches."

Mantis Pheromones[]

"Your crew's movement speed is increased by 25 percent."

  • Applies both on your ship and when boarding an enemy.
  • The Mantis Cruiser (A, B and C Variants) starts with this augment.
  • Can be acquired by any ship through the Mantis Cruiser unlock event, even if the Mantis Cruiser has already been unlocked.
  • Cost: 50 Ftlgame-scrap.png
  • Somewhat useful, especially when boarding with 2 crew. Faster movement is helpful with advanced boarding techniques. Less relevant on 4-crew boarding setups.
  • In practice, Mantis Pheromones seems to give about a 23% speed increase.

Crystal Vengeance[]

"Every time your ship takes damage, there is a 10 percent chance to break off a shard that flies at your enemy."

  • This counts as a normal missile shot that does 1 damage and has a 10% chance to breach. Like any other projectile, the enemy can dodge it with their current evasion percentage.
  • The Crystal Cruiser (A and B Variants) starts with this augment.
  • Can be acquired by any ship through the Crystal Cruiser unlock event regardless if the Crystal Cruiser has been unlocked.
  • Cost: 80 Ftlgame-scrap.png

Zoltan Shield[]

"An unexplained technology creates this nearly impenetrable shield. Only the energy outburst from an FTL engine is powerful enough to recharge it."

  • Cost: 80 Ftlgame-scrap.png
  • Upon arrival at a beacon, you start with an additional green energy shield that will absorb 5 points of damage before your standard shields and hull will start to take damage.
  • Absorbs damage from all weapon types, including missiles, bombs and beams, but takes twice as much damage from ion weapons. Beam weapons deal their room damage twice to the shield (including the Artillery Beam). With precise use of some beams, it's possible to get through a Zoltan Shield and deal damage to one or two rooms. Aiming the Hull Beam at systemless rooms will not increase damage on the Zoltan shield.
  • Until they are destroyed, Zoltan Shields prevent boarding, hacking, and mind control. However, the Zoltan Shield Bypass augment will allow boarding, bombs, and mind control. Certain events that spawn intruders aboard your ship are explained in-game by the enemy having this augment.
  • Leaving and returning to an area with an enemy ship that has a Zoltan Shield will cause the enemy's shield to replenish.
  • Pulsar waves cannot penetrate the Zoltan Shield, but will quickly strip it.
  • The Zoltan Cruiser (A, B and C Variants) starts with this augment.
  • Can be acquired by any ship through the Zoltan Cruiser unlock event, even if the Zoltan Cruiser has already been unlocked.
  • Phase 3 of The Rebel Flagship uses a more powerful version of the Zoltan Shield.

Damaged Stasis Pod[]

Spoiler warning: The following contains spoilers for the game. Continue at your own risk if you do not mind ruining some fun of the game.

"This bizarre alien artifact appears to be barely operational. It has no practical function but perhaps someone can repair it."

  • This "augment" is used exclusively in an event sequence to access the Hidden Crystal Worlds.
  • Can only be acquired during the Dense Asteroid Field Distress Call random event.
  • Can only be used during the Zoltan Research Facility random event.
  • More than one Stasis Pod can be acquired and held at a time; each one will occupy an augmentation slot. It is also possible to encounter multiple Zoltan research facilities (even in the same sector), and each one will open a single pod.
  • Cost: 30 Ftlgame-scrap.png
