Ships and ship names
- The Kestrel Cruiser is a reference to the Escape Velocity series by Ambrosia. Also a spacefaring simulator, The Kestrel is the popular and most powerful civilian ship available in Escape Velocity and returns as a powerful endgame ship in Escape Velocity: Nova available upon game completion.
- Layout B of the Rock Cruiser (Shivan) is possibly named after the Shivan race in the game Freespace. The color scheme is evidence of this, although the Shivan race in that game utilizes more shielding than armor, in contrast to the Rock ships. (Not entirely true. Note: Shivan bombers have enormous amount of armor plating, especially the Nephilim class which is really hard to shoot down with shields down, even with missiles)
- Layout A of the Crystal Cruiser (Bravais) is named after a Bravais lattice - a mathematical method of describing/representing a crystal structure and the points within it.
- Layout B of the Zoltan ship (Noether) is named for Emmy Noether, a groundbreaking mathematician and physicist.
- The Nesasio is probably designed after Mass Effect's SSV Normandy, as both are stealth-themed ships, share a similar delta form, and have similar room layouts (FTL's being a simpler version).
- The Kestrel (Kestrel A), Red-Tail (Kestrel B), The Swallow (Kestrel C), The Osprey (Federation A), The Fregatidae (Federation C), The Shrike (Lanius B), and The Nesasio (Stealth A) all share their names with a bird or a bird genus. The Gila Monster (Mantis A) is a species of venomous lizard, Ariolimax (Slug C) is the genus of the banana slug, and a Basilisk (Mantis B) is a legendary reptile.
- The Shrike could also be a reference to the almost mythical mechanical terror from Dan Simmon's Hyperion cantos, especially considering the resemblance between it and the Lanius. Shrike is also a killer robot in book Mortal Engines, and it has knife-like claws in both its hands.
- Nisos (Fed B) was king of Megara, and Simo-H (Stealth C) is a shortened version of Simo Häyhä, who was a Finnish sniper.
- Theseus (Mantis C) was the mythical founder of Athens; furthermore, the eponymous Ship of Theseus refers to a ship which had all of its parts replaced, but still considered the same ship - a situation which is bound to happen to your boarding party, as the ship is outfitted with a clone bay.
- A Torus (Engi A), Vortex (Engi B), and Tetragon (Engi C) are all geometric terms that describe the shape of the ship: a torus is donut-like, vortices loop around many times, and tetragons are four-sided.
- Cerenkov (Zoltan C) could be a reference to the physicist or radiation (Cherenkov radiation is caused by particles moving faster than light in a medium).
- Bulwark (Rock A), Tektite (Rock C), and Carnelian (Crystal B) are types of minerals.
- The Man of War (Slug A) is both a kind of warship and a kind of jellyfish., in reference to the warship resembling a jellyfish.
- Several beam weapons are named after polearms, a category of spear-like weapons known for their long reach:
- Several missiles are named for Greek myth:
- "Lanius" is Latin for "Butcher".
- Lanius ships, especially the non-player ones, look very similar to the Shadow Ships from Babylon 5.
- When renaming a ship, entering a blank string automatically renames it "The Nameless One."
- In a random encounter with a pirate, the pirate will refer to himself as The Dread Pirate Tuco, a reference to The Dread Pirate Roberts from the book and film "The Princess Bride."
- Tuco was the name of Eli Wallach's character (The Ugly) in well-known Spaghetti Western "The Good, The Bad and The Ugly."
- The visual effect during an FTL jump (a bright flash of light that travels along the length of the ship) bears a striking resemblance to the FTL jump effect in the remade Battlestar Galactica series.
- In a random mission, you will come to a station and when asking to refuel, the station's respond will be, "Go away! We don't serve your kind here! (Star Wars Episode IV: A New Hope, during the cantina scene, a quote from the bartender to R2-D2 and C-3PO)
- If you run out of fuel and wait, one of the ships that finds you is described as a modified YT-1300 Freighter obviously used for smuggling. This is a reference to the Millennium Falcon from Star Wars.
