LAST PULSE - Horror Tracks & Interactive Sound Effects

Veinhold, 2089. The Rupture has torn reality open, Hemocyte-X has turned humanity into the Thirsting, and the Architect is "renovating" what is left. The Last Pulse is a horror audio collection built for that world, and ready for yours.

Everything was synthesised and composed from scratch for this pack. There are no samples, no recycled libraries and no cloned voices, so you can use it with confidence in commercial games.

What you get [current release]

10 horror sound effects: zombie snare, sword strike, a fictional 2089 pistol and shotgun (with dry versions for engine reverb), layered Thirsting growls, a wet blood-pulse loop, Hemocyte infection, the Architect's surgical drill, the Webbed Staircase emitter and the Rupture. Most have 2-3 variations so repeated hits don't sound repetitive.

6 procedural voice designs: a distressed Thirsting, the Hollow Church's ritual chant, the Children of the Pulse's whispered prophecy, a Remnant radio transmission (static, squelch and Morse), the mechanically altered Sculpted, and the Lost humming a half-forgotten lullaby. [4 scripted character lines are in production and will be added as a free update.]

10 original music tracks (about 20.5 minutes): exploration, dread, pursuit, the Architect's lullaby, the Hollow Church, the Webbed Staircase, Sera's memory theme, the industrial Rebirth Chamber, a combat track with a seamless 64-second loop, and the main theme. Every track includes stems that sum exactly to the mix, plus MIDI.

10 interface sounds: hover (3 variations), select, inventory open/close, mission accepted/failed, a looping low-health warning, an infection warning, humanity up/down, and save point.

10 gameplay feedback effects: enemy detection (near/far), a Blood Sense trigger and loop, stealth success/failure, a critical-health heartbeat at three intensities, infection stages, memory discovered, mercy confirmed, an empty weapon, and a safe-zone stinger and bed.

A recurring Last Pulse motif runs through the music, the Architect's drill pitch, the Sculpted's voice and the Lost's humming, so the whole soundtrack feels like one world.
