About This Game

One gauge. No health bar, no ammo, no timer.

Fast shooters all need an engine that forbids waiting. This one uses

thermodynamics. Your core heats up when you fire, and the only heat sink in the

game is the air moving over your body.

The consequence needs no tutorial: take cover to shoot in peace, and you melt in

eight seconds.

The ground is where you burn

Walking doesn't cool you. Sprinting doesn't cool you. [b]Standing on solid ground

dissipates nothing at all[/b] — and the faster you fly, the harder you cool.

Every weapon's recoil is a thruster. The starter pistol pushes back exactly as

hard as gravity pulls, so holding the trigger holds your altitude. You do not

shoot [i]and[/i] move. Shooting [b]is[/b] moving.

The red zone pays

Damage scales with your own temperature. At 92% you hit nearly twice as hard, so

the whole economy of the game pushes you to the edge of an explosion and keeps

you there. Overheat and you spend a cycle. Spend your last one, and the core

melts.

Three ways to play

• LA DESCENTE — the campaign. Five sectors, five rooms each, a boss at

the bottom of every one, and an ending. Each boss makes one rule compulsory that

the rest of the game only rewards: the red zone, flight, weapon rotation, a

deliberate overload. Learn one, and the next one sends you back to school.

• LA COULÉE — endless waves, one arena, one score.

• LA VOLÉE — twelve movement courses, no enemies at all. A launch pad, a

void, a gate and a clock. Two ways to lose: the void, and your own core.

And a foundry between runs

Ingots earned in a run buy permanent upgrades — and every one of them can be

refunded at any time, in full. A meta-progression you can permanently get

wrong is a trap, not a system of choices.

Six weapons. Twenty-two species. Five bosses.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

The text in HEATSINK — its interface strings and its translations — was written with the assistance of generative AI.

Nothing is generated while you play. There are no AI-generated images or audio in this game, because there are no image or audio files at all: every shape on screen is drawn by code, and every sound is synthesised when the game launches.
