ACCRETION: THE VEIN

Accretion app icon

One thumb. One button. Five parasite structures, ten layers deep — and the nuclear fire never stops. An arcade cave-flyer for iPhone.

The ship flying the vein, the nuclear fire two metres behind, a drone ahead
Two metres ahead of the fire. Do not slow down.

The Accretion is eating the star system — and the only way to kill a structure is one small fighter, flown down its own throat. Read the AAF briefing →

THE GAME

ONE THUMB, ONE BUTTON

Drag to fly. Push to burn, pull to brake. The main gun fires itself — your thumb is for the line, and the one button is the smart bomb. Full controller support, experimental and honest about it.

THE FIRE NEVER STOPS

Every tunnel triggers the Accretion's failsafe: a wall of nuclear fire that enters behind you and never slows. The only thing that holds it at bay is the guardian waiting at the core. Nothing survives it. Keep moving.

5 STRUCTURES, 50 LAYERS

Each structure runs ten layers deep — breach the sealed vents, fight the outer and inner guardians, and kill the core to set off the chain reaction. Every vein is generated, and every one is provably flyable.

EARN, ARM, DESCEND

Score converts to credits; credits buy ships, weapons, launch levels, plating, and the shield enhancer in the hangar. Nothing rescues a run. Everything shapes the next one.

THE ACCRETION FIGHTS DIRTY

Drones, swarms, turrets, five guardian voices — and bait: corrupted tech seeded on the easy line that degrades your weapon if you brush it. The reward is always in the dangerous place.

EVERYTHING IS GENERATED

The tunnels, the sounds, the music, the icon, even the block-letter title font — all procedural, all fuzz-tested for fairness. If a vein exists, it can be flown.
