"This was supposed to be for use in Nebulas and other, more creepy areas, but listen to the thing! FTL is not a psychological horror game, and this track was way too freaky and claustrophobic. Still pretty cool, though."FTL: Faster Than Light is light on graphic depictions of violence and horror, leaving it up to the player's imagination to fill in the gruesome blanks.
—Ben Prunty, the composer of the FTL soundtrack, on the Cut Song "Horror"
The Nightmare Fuel must have a Zoltan Shield Bypass!
- The Giant Spiders Random Event. The first possible option is sending in your crew, and if you're unlucky, your crew gets to deal with massive spiders coming out of a vent, before you finally leave, losing a crew member in the process.
- The Damaged and Dilapidated Space Station Random Event. The whole place is filled with corpses and the stench of death and decay. If you're unlucky, one of your crew members can contract the fatal disease that wiped out the station, and not even a Clone Bay will save them (an Improved Medbay will, though).
- The Mantis's sprite resembles that of a spider. Imagine you're just merrily jumping from sector to sector when all of a sudden, the alarms go off and there are six of these insectoid creatures after your blood.
- In an event you can find in Zoltan sectors, one of your crew members undergoes rapid reverse aging until they disappear.
- Nebula sectors can be frightening due to the empty-sounding explore music. With every jump, there comes the risk of enemy ships, which doesn't sound too bad, or a Boarding Party that you may have trouble locating due to your sensors being unusuable. If you aren't paying attention to the narration, the sudden "INTRUDERS DETECTED" warning can come off as a Jump Scare. The worst part about boarding parties is that unlike ships, which are marked on the map if you have updated map data or Long-Range Scanners, there's no way of telling if your next jump will dump you into boarder territory.
- Ion Storms can come as a Jump Scare by playing the loud thunder noises as soon as you jump into one.
- Slug ships in Slug-controlled nebulas can shut off your oxygen. We hope you like asphixation!
- On the original soundtrack, there is a bonus track aptly called "Horror". This was supposed to be one of the nebula sector tracks, but was removed because it was considered too scary. So if you think the current nebula tracks are scary, be glad this track didn't make it in.
- When enemy crew die, they don't make any noises. When your crew die, you get to hear anywhere from the grinding clank of Engis being dismantled to humans groaning in pain as their last bits of HP are wiped out.
- The event of finding weird horse like creatures. Don't try to sell them to slavery.
- The Explore version of "Debris" sounds very lonely and ghostly, painting the feeling of exploring abandoned wreckage in dark areas of space. The Battle version sounds less ominous, but is reminiscent of alien abductions.
- When you fight an enemy ship, the game will reward you with extra loot if you manage to wipe out its crew without destroying it. This normally requires a boarding action and brutal fight to the finish, but there's other options:
- Disable or destroy their life support systems and wait as all the oxygen leaks out of the air and they suffocate to death. This takes an especially horrific aspect if you find yourself blasting the oxygen and/or medibay compartments every time your desperate opponents manage -- briefly -- to get them operational again.
- Use fire weapons to set fire to their entire ship.
- Combine the two to give the enemy the choice between burning to death or suffocation!
- Lanius can teleport into the enemy O2 bay and start draining oxygen immediately as well as blowing it up. Without an immediate overwhelming attack, this can result in the Lanius standing in an oxygen-deprived O2 room laughing as the enemy crew run around knowing their oxygen will slowly move from room to room and their only chance will be to charge into an airless room to fight a metal man who doesn't need oxygen to survive.
- Combine that with an Hacking Drone targetting the same O2 bay. Cackle maniacally about the ensuing result.
- The Anti-bio beam, a weapon that deals damage only to crew, works too. Imagine your comrades at arms suddenly dropping dead around you mid-battle, like puppets with their strings cut.
- Advanced Edition introduces the Lanius race. What do they do? They not only can survive without oxygen, but they absorb it from whatever rooms they're in. Their presence on an enemy ship means bye-bye to the victims' air supplies.
- Hacking the medbay doesn't just deactivate it, it hurts anyone who's unlucky enough to be in it at the time. Since hacking a room also seals the doors, anyone in there is probably going to die. Since the medbay works by pumping people full of healing nanomachines, they're going to die a death of a trillion cuts frantically trying to force a door open as the room that was supposed to heal them tears them apart.
- There was a "Ghost" race and ghosts ships planned, as mentioned on the main FTL page. The AI that takes over the Rebel Flagship if you kill of its crew is, by the game's coding, actually an invisible, invincible ghost. One way to interpret it is the ship becoming haunted if you kill off the crew.
- For those fighting the Flagship's second phase for the first time, the distinct "WARNING — POWER SURGE DETECTED" klaxon gives you that dreadful feeling that something very, very bad is about to happen to your ship.
- Some of the "uneventful" beacons. There are quite a few beacons where you find abandoned mines and no life signs are detected, with no clues given as to why they're completely empty. And then there's the event where "a rudimentary automated planetary defense system is looping its message into space: "Warning! Quarantine Level 5 in effect under FHA Act 22, article 11.2. Warning! Quarantine Level 5..."" - Just what is going on there?
- The Crystal race have a power called lockdown, which surrounds a room in crystals, preventing anyone getting in our out. There is an achievement for doing this to four enemies at once. Its called 'No escape'.
- Using the mind control system on enemies, turning them against their crewmates. Imagine some one you've know for years suddenly trying to kill you. It gets worse with upgrades as those controlled have increased health and damage.
- Combining this with the teleporter allows you to abduct an enemy crew member every 20 seconds. Imagine being taken over, fighting your friends then regaining control, only to find yourself on any enemy ship surrounded by hostile forces.
