The Complete Guide to Bullet Hell Subgenres (Yes, There Are This Many)

If you tried to draw the bullet hell family tree on a napkin, you'd run out of napkin. The genre has been splitting and recombining for thirty years and the offspring have offspring now. Some of them are arguing with each other at family dinner. Most of them refuse to share a Steam tag.

This is the field guide. One pass through every flavor of bullet hell currently making games, with examples, defining traits, and notes on which audience each one is for. Bookmark it, send it to confused friends, refer back when a Steam tag lies to you.

The trunk: classical danmaku

The original. Cave-style, Touhou-style, whatever-the-arcade-cabinet-was-running-in-1997-style. Vertical or horizontal scrolling, you fly a small ship or a small witch, the screen fills with bullet patterns that look like origami unfolding, and you thread the gaps.

Defining trait: the bullets are the level design. Enemy variety is decoration. The real game is reading patterns and finding the safe lane.

Modern entries: ZeroRanger, Crimzon Clover, Mushihimesama, the entire Touhou mainline, DoDonPachi DaiOuJou.

Audience: people who like sheet music made of projectiles. High skill ceiling, devoted fandom, scoring-system depth that makes chess look casual.

The branch that ate the rest of indie: bullet heaven

The Vampire Survivors family. Not really bullet hell at all once you look at the verb—you're the one filling the screen, not the one dodging. Auto-attacks, build optimization, escalating swarm waves, run-based meta-progression.

Defining trait: power fantasy via numbers. The bullet count is yours.

Modern entries: Vampire Survivors, Brotato, Halls of Torment, Death Must Die, 20 Minutes Till Dawn, Magic Survival.

Audience: optimization brains, build-crafters, anyone who loved the moment in Diablo when their character became a god. I unpacked the full split in bullet hell vs bullet heaven because the genre confusion is doing real damage.

Roguelike bullet hell

Bullet hell plus permadeath plus procedural rooms plus item synergies. The branch that explained Enter the Gungeon to a generation that didn't grow up on shmups.

Defining trait: each run is short and chaotic, the dodge skill matters but the build matters too. Hybrid muscle memory.

Modern entries: Enter the Gungeon, Tiny Rogues, Star of Providence (formerly Monolith), Neon Abyss.

Audience: roguelike fans who want twitch on top of their RNG. The Gungeon is the canonical entry point and probably always will be.

Twin-stick bullet hell

You aim independently of where you walk. The screen still fills, but now you're a brawler with a mouse, not a ship on rails.

Defining trait: directional aim breaks the genre's traditional auto-fire-forward grammar. Movement and aim are two separate puzzles.

Modern entries: Nuclear Throne, Hotline Miami at the edges, Geometry Wars, Helldivers 2 if you squint.

Audience: people who find the rigid forward-fire of classical shmups limiting and want more agency in the chaos.

Boss-rush bullet hell

Strip out the levels. Keep only the boss fights. Each fight is its own bullet pattern puzzle, often with phases, often gorgeous.

Defining trait: no traversal, no chaff enemies, just patterns and a healthbar.

Modern entries: Furi, Titan Souls, Cuphead in spirit if not in genre tag, Hyper Light Drifter at moments.

Audience: people who skip to the bosses anyway. Pattern-puzzle obsessives.

Bullet hell platformer / metroidvania hybrid

The screen-filling bullet patterns adapted to a side-scrolling traversal game. Rare, precious, hard to design.

Defining trait: you're not just dodging in 2D space, you're dodging while platforming, which means the bullet patterns have to account for gravity, ledges, and intentional positioning.

Modern entries: Touhou Luna Nights, Record of Lodoss War: Deedlit in Wonder Labyrinth, Hollow Knight in specific fights.

Audience: people who want the bullet hell language in a richer world. Smaller scene but devoted.

Turn-based bullet hell

Yes, this is real now. Enter the Chronosphere came out in May 2026 with the wild conceit that the world only moves when you do, and suddenly the bullet patterns are puzzles to be reasoned through rather than dodged in real time.

Defining trait: the time pressure that defined the genre is gone, replaced by spatial reasoning. You see the bullet, you plan around it, you commit.

Modern entries: Enter the Chronosphere is the cleanest example. Cobalt Core has shades of it. The subgenre is too young to have a deep bench yet.

Audience: tactics fans, puzzle brains, anyone who always wanted to play DoDonPachi but only had the reflexes for chess. I wrote the dedicated piece on this branch over in turn-based bullet hell as an emerging subgenre.

Open-world bullet hell roguelike

The newest branch on the tree. Take the dense bullet patterns, the run structure, and graft them onto an open exploration map where you choose your routes and your fights. PUNK is in playtest as I write this, and the design space it's opening up is the kind of thing that produces a genre offspring or a beautiful failure—either way, worth watching.

Defining trait: spatial freedom inside a genre traditionally defined by linear stages. The exploration loop and the combat loop pull in different directions, and how a designer balances that is the whole game.

Modern entries: PUNK (in playtest), elements of Hyper Light Breaker, gestures in this direction from a few experimental indies.

Audience: too early to say. Watching the scene closely. Covered the emerging shape in open-world bullet hell as a subgenre.

Spellcaster bullet hell

The wizard branch. You're not piloting a ship, you're casting—projectiles that orbit, beams that chain, AOEs that bloom—and the screen fills with magic instead of metal. The Spell Brigade just left early access and crystallized the subgenre into something nameable.

Defining trait: the bullets are flavored as magic, which sounds cosmetic but actually changes the design language. Spells chain, scale, combo with each other in ways guns don't.

Modern entries: The Spell Brigade, Magicraft, Magicka in spirit, Noita as a wild edge case.

Audience: people who like Vampire Survivors but wish their character was a wizard. Bigger audience than you'd think. Full breakdown in the spellslinger bullet hell microtrend.

The hybrids that don't fit anywhere

There's a whole drawer of games that share bullet hell DNA without committing to any one branch. Returnal is a third-person bullet hell roguelike with sci-fi horror dressing. Devil Daggers is a bullet hell first-person shooter you can finish in a minute or never. Hades dabbles in bullet hell language without being one. Genres do this—they leak into adjacent genres and produce things that are technically uncategorizable.

Don't let the tag confusion stop you from playing them. The verb test from the heaven-vs-hell breakdown still works. If you're dodging more than dominating, you're in the family.

Why the family tree keeps splitting

Genres split when designers find a constraint that produces a different game. Turn-based broke the time-pressure constraint. Bullet heaven flipped the bullet-direction constraint. Open-world is breaking the linear-stage constraint. Each split started as a weird experiment and grew into a subgenre with its own fans and its own design problems.

There will be more. Someone is going to ship a co-op bullet hell that actually works and that'll be a branch. Someone will ship a narrative bullet hell where the patterns tell a story and that'll be a branch. The tree is still growing. Keep watching.
