A Cursed Bloodline

DUSKVEIN

BLOODLINE

The last cursed heir of a dying bloodline.

Every night the Duskveins open — bleeding seams of shadowlight that spit the dead, the broken, and the cursed back into the world. You're the last vessel of a fading line, and the only thing left to hold the dusk in place. Survive. Evolve the curse. Break the line before it breaks you.

Four things this game does, and does hard.

A survivors-like built around chaos scaling, cursed evolution, and bosses that don't forgive sloppy runs.

01 / 04

Survive the dusk

Veins crack open and the dead pour through. Hold the arena until the dusk closes.

Detail
02 / 04

Evolve the curse

16 source weapons fuse via Bloodseals into 8 evolved forms. Builds spiral fast.

Detail
03 / 04

Break the line

Five handcrafted bosses are live, each with signature mechanics — no recycled health-sponges.

Detail
04 / 04

Walk the bloodline

200 nodes across the new tree: 6 Keystones, 18 Notables, and 176 Small Nodes. Your line gets meaner every run, even when you die.

Detail
Trailer

One minute of cursed combat.

No cinematics. Just hordes, chain reactions, and the moment a build breaks open.

Arenas

Five places the dusk leaks through.

Each arena is hand-built: its own enemy roster, its own boss, its own way of killing you. No procedural mush — every floor is intentional.

Arena I / V

Cursed Graveyard

Bonefields, broken chapels, soil that breathes.

Boss · Malgor, the Rot-Abbot
Arena II / V

Gloamwood

Dusk-weavers in the gallows roots. Spiders and lingering wisps.

Boss · Gallowroot
Arena III / V

Cinderforge

Cursed casting ruin. Lava, slag, the executioner’s wheel.

Boss · Carnreaver Executioner
Arena IV / V

The Vein Cathedral

Three rooms beneath the city. The saint is awake.

Boss · Veyrath, the Vein Saint
Arena V / V

The Rift

Riftweaver dimension. Three chambers. Reality is the boss.

Boss · Riftweaver Mage
Bestiary

Every arena has something waiting to ruin your build.

Five boss encounters are live at alpha, with three featured here. Each main boss drops a Bloodseal — guaranteed — which fuses two of your equipped weapons into an evolved form. Survive the duel, claim the seal, and turn the run sideways.

Weapons

Every upgrade feeds the chaos.

16 source weapons. Auto-fire. Five slots. Pair two of them with a Bloodseal and they collapse into an evolved form — and free a slot for the next curse.

Source · BloodLV. 1

Cadaver Ignition

Slain enemies detonate. Lethal in dense crowds — and dense crowds are the only kind we ship.

Pairs · Chain Lightning
Source · VeilLV. 2

Vein Rail

A focused crimson beam that punches through formation. Patient builds win whole rooms with this.

Pairs · Blood Tornado
Source · BoneLV. 3

Phantom Sickle

Sweeping reaper-arc that returns to you. Punishes enemies who get too comfortable behind cover.

Pairs · Hollow Ring
Source · AshLV. 4

Plagueveil Rain

Toxic curtain falls in a circle around you. Stand in it — let it work.

Pairs · Gravetide Spikes
Evolved Weapons · Bloodseal fusion

Two source weapons. One Bloodseal. A curse you can't take back.

8 evolved forms · Bloodseals from bosses only

Stack two — survive. Stack three — break the screen. Stack four — break yourself. The system rewards the player who can read the floor mid-detonation.

Bloodline Tree

200 nodes. Six Keystones. One cursed line.

Ashes carry across runs. Spend them on 6 Keystones, 18 Notables, and 176 Small Nodes that quietly turn the dial — until a Keystone changes the math entirely.
