Eleven figures on a ridge at dusk looking down at a walled colony, a crashed drop-pod to one side, two moons in the sky

Xenotypes

Eleven theme tracks, one for each of the main xenotypes on the rim. In-game music: no lyrics, one shared sound, and a different feel for every people.

The sound

Every track is built on the same palette: fingerpicked acoustic guitar, warm analog synth pads, sparse deep percussion and a wide dusty reverb — a frontier sci-fi ambient sound in the spirit of the game's own soundtrack. Each xenotype then adds one or two signature instruments and its own tempo and mode, all in the key family of D so the album plays as one piece.

The range

From the slowest, the Neanderthals' 46 BPM ritual drums that never hurry, to the fastest, the Impids' 132 BPM desert gallop. The Hussars' martial charge and the Neanderthals' immovable weight are the album's two poles: the quick combat-honed machine against the slow unstoppable force.

How it was made

Music generated with Suno from written style and arrangement prompts. Artwork generated locally with a painted-illustration look, one image per track and a cover of all eleven together. Title and song documents live alongside this page.

  1. An ordinary colonist sitting on a crashed drop-pod at dawn with a mug, looking over a valley
    01

    Baseline

    Baseliner 76 BPM · D major / Mixolydian · solo guitar → full ensemble → solo guitar

    A colony's first morning on a new planet. The reference track: the pure palette with nothing added, open and quietly hopeful.

    Brushed kit, clean electric swells, pedal-steel-like slides.

  2. A grey-skinned miner swinging a pickaxe at an ore seam by lantern light
    02

    Deep Vein

    Dirtmole 52 BPM · D minor · drone → dense low ensemble → drone

    Grey-skinned miners who see in the dark and flinch from the sun. Subterranean and heavy, patient and blind, quietly industrious.

    Palm-muted guitar, bowed double-bass drone, tapping percussion like distant pickaxes, felt piano.

  3. A hairless, thin engineer assembling a glowing component at a white workbench
    03

    Clean Room

    Genie 100 BPM · D Lydian · layers added one at a time, removed one at a time

    Hairless, long-fingered engineers built for the space navy, brilliant and fragile. Clockwork motion, precise and elegant.

    Sixteenth-note synth arpeggios, glassy bell plucks, clicky percussion, guitar reduced to harmonics.

  4. Two figures close together on a porch at dusk, hands joined
    04

    Lovebond

    Highmate 84 BPM · 3/4 waltz · D major with major sevenths

    Beautiful, gentle, psychically bonded companions who cannot raise a hand in violence. A tender waltz that rises to one lush peak and settles back to piano alone.

    Glassy electric piano, chorused guitar, brushed snare, shimmering high synth swells.

  5. A squad of red-eyed soldiers in grey armour advancing through dust
    05

    Go-Juice

    Hussar 120 BPM · D minor · ratchets up in steps, cuts dead on a final brass hit

    Red-eyed engineered super-soldiers, relentless, held together by their next dose. Disciplined, aggressive, machine-like stamina.

    Hard-strummed muted guitar pulse, snare rolls and marching snare, floor toms, distorted low brass stabs.

  6. Horned, orange-skinned figures sprinting across a cracked desert under a white-hot sun
    06

    Dustrunner

    Impid 132 BPM · D Phrygian dominant · sprint → smouldering half-time → sprint

    Horned, fire-breathing desert runners, fast and wild. The fastest track on the album, restless and reckless and sun-scorched.

    Galloping darbuka and frame drums, fuzzed slide-guitar lead, rapid fingerpicked runs, heat-haze tremolo pad.

  7. A heavy-browed tribe around a night fire, beating log drums
    07

    Old Blood

    Neanderthal 46 BPM · D minor · every layer enters late and stays

    A slow, unstoppable tribe that was old before the rest of us were born. The slowest track on the album: a three-note chant that never varies, and drums that only ever get heavier.

    Log drums, wooden slit drums, stomping floor toms, rattles, unison handclaps, low wooden flute.
    Listen on Suno →
  8. A cheerful crew of pig-eared, snouted people in a muddy farmyard, one sitting on explosives crates
    08

    Trotters

    Pigskin 92 BPM shuffle · D Mixolydian · slide guitar alone → stomp section → slide guitar alone

    Snouted, hardy, cheerful, and able to eat anything. A swampy stomp-blues bounce, good-natured and sturdy and lazy.

    Resonator slide guitar, jaw harp, foot-stomp kick, handclaps.

  9. A pale figure lying in an open ornate casket in a shaft of moonlight, a machine with a red glow beside it
    09

    Deathrest

    Sanguophage 58 BPM · D minor with Phrygian shading · near-silence → organ bloom → the heartbeat stops

    A centuries-old blood-drinker sealed in its casket, dreaming. Nocturnal, seductive and patient, gothic and ancient.

    Nylon-string guitar, sub-bass heartbeat pulse, bowed cello drone, glassy music-box, one church-organ chord.

  10. A gaunt grey-skinned figure grinning in a polluted wasteland as yellow-green fallout drifts down
    10

    Toxfall

    Waster 88 BPM · D minor · thin and sick → heavy distorted → wobbling pad alone

    Grey, gaunt and immune to the poison that falls from the sky. Sludgy and grimy, defiant and hollow-eyed, strangely proud.

    Lo-fi fuzzed guitar, detuned wobbling pads, distorted bass drone, clanking metallic percussion.

  11. Fur-covered warriors on a frozen ridge, one raising a horn, beasts surging forward below
    11

    Warcall

    Yttakin 96 BPM · D Dorian · lone fiddle → thundering march → a single horn call

    Fur-clad warriors calling their beasts across the ice. Fierce and loyal, cold and proud — the most epic track of the eleven, as it should be.

    Bowed fiddle and nyckelharpa drone, frame drums and floor toms, long low horn calls.
