How to Play MUGEN Characters in the Browser (No Install)

Play MUGEN Characters in the Browser — No Install

For more than two decades, playing MUGEN characters meant downloading a local engine, unpacking files into the right folders, and hoping everything was configured correctly. Tarunk Engine changes that: load MUGEN-compatible characters and battle in your browser — no install, no download, no setup.

What Does "MUGEN-Compatible" Mean?

A MUGEN character is defined by five plain-text and binary formats:

• .cns — state definitions (the character's state machine: idle, walk, jump, attacks, get-hit)
• .sff — sprite data (images plus their axis/anchor points)
• .air — animation definitions (how sprites play in sequence)
• .snd — sound definitions (hits, K.O., voice lines)
• .cmd — command definitions (input combos like quarter-circle-forward)

Tarunk Engine reads these original file formats directly — that is what "MUGEN-compatible" means here. No conversion, no re-export, no plugin. If a character was built for MUGEN or Ikemen GO, it will almost certainly run on Tarunk too.

How to Play MUGEN Characters in Your Browser

1. Open the Tarunk Engine play page.
2. Drag & drop a character .zip or .rar (up to 200MB) straight onto the screen — or pick one of the built-in template characters.
3. Select your fighters and press start.

That is the whole flow. The engine resolves the state machine, hitboxes, animations, sound, and AI in real time — at 60fps, inside your tab.

Built-In Templates to Try Right Now

No files handy? The engine ships with two original characters you can play immediately:

• TARUNK Bot — the free template character with 241 sprites, 117 animations, and 58 states (read the full showcase)
• TARUNK Ember — a second original fighter with its own palette

Both are fully playable and perfect for testing the engine before you dig out your own character collection.

Honest Compatibility Notes

• Your files are processed 100% in your browser — nothing is uploaded to a server, so your characters stay private.
• The free tier includes one custom character upload; upgrade to Pro or Enterprise for unlimited uploads.
• Standard .cns/.sff/.air/.snd/.cmd work out of the box. Exotic engine-specific hacks from the classic era may behave differently — we target the mainstream MUGEN 1.1 feature set.
• Stages and BGM are supported too — drop a full stage zip alongside your fighters.

Create Your Own Characters

Playing is only half the story. Tarunk Studio turns a MUGEN-compatible character into a visual editor: drag hitboxes, reorder animations, edit state machines, and export your build — all in the browser. New here? Start with the command grab tutorial or remix the TARUNK Bot template.

Finished characters can be published to the Assets Store — free or paid, with wallet payouts.
