About This Game

HELL IS A NINE-CIRCLE TOUR

You are a doom metal band. The venue is Hell. Twenty-seven gigs stand between you and getting off this stage — three fights per circle, nine circles deep, with a boss waiting at the end of each one.

VESTIBULE is a roguelike deckbuilder about building a band, stacking riffs, and hitting hard enough to kill things that are already dead.

STRIKES, NOT TURNS

Every fight gives you a set number of Strikes to work with — four, most runs. Between them you play cards: riffs that buff your members, utility that keeps you alive, embers that pay for all of it.

Then you Strike, and every member swings at once — one multiplier cascade of cards, Riff Chains, artifacts and pedals, all stacking into a single number.

BUILD THE BAND

Eighteen musicians across nine roles — guitarists, a drummer, a synth player, a vocalist, and a few things that aren't technically people. Ten keywords define how they play, and they stack: FRENZIED, BLASTBEAT, DISSONANCE, DIRGE, ANCHOR, TRICKSTER, and more.

Only the third fight of each circle — the boss — has a real trick up its sleeve. The Drifter survives its own death, once. The Devourer heals off every card you play. Lucifer gets two full health bars.

SIXTEEN RIFF CHAINS, NONE OF THEM LABELLED

Certain cards, played in the same Strike, chain into each other for a real multiplier spike. The chains aren't listed anywhere in the UI — you find them by playing. (There's a toggle if you'd rather just be told.)

THE DESCENT

Nine circles, Dante's own, three fights each: Limbo, Lust, Gluttony, Greed, Anger, Heresy, Violence, Fraud, Treachery. Then Lucifer — two phases, 6,660 HP — waiting at the bottom. About one run in a hundred sees him dead. He's meant to be a wall.

Between fights: a shop, a descent choice, and if you've got the Stash for it, a trip from the Dealer — special items, each one a gamble on a one-fight buff that can just as easily go bad.

FIVE DECKS, FIVE STAKES

Five starter decks, each a different way to play: Standard's balanced and chain-dense, the Shredder is pure aggro, the Chaos deck reshuffles itself at random every single run, the Engineer builds around card copies, and the Survivor gives every member a second chance before they go down. Beat one, unlock the next.

Climb the Stakes and the whole thing gets meaner — more enemy damage, pricier shops, no heals between fights — until Demonic drops you to three Strikes a fight instead of four.

THE MUSIC IS REAL

The soundtrack is doom metal, recorded rather than assembled. Real riffs, written for the circle you're standing in.

EARLY ACCESS — LAUNCHING OCTOBER 2026

Vestibule is in active development. Everything above — the band, the decks, all nine circles, Lucifer — is built and running. What's left before launch is balance, polish, and whatever more playtesting turns up.

AI Generated Content Disclosure

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

Vestibule's pixel art was generated with an AI art tool, with every design directed, refined, and hand-edited by the developer. Individual trailer and cinematic clips were generated with an AI video tool, built from the game's own artwork and developer-written scene descriptions — the final edit, scene sequencing, and music timing were done manually by the developer in After Effects. All game design, systems, writing, and code are original work.

Mature Content Description

The developers describe the content like this:

Vestibule includes an optional, minor gameplay system: between fights, players may buy items from an in-game character referencing recreational substances for a temporary, randomized in-battle effect. This is a small side-mechanic played for the game's dark comedic tone, not a focus of the story or a major system — no drug use is depicted on screen, and its effects are limited to numerical stat changes.
