the story

He was out. Then his brother went missing.

Marcus "Atlas" Reed is a former bounty hunter, retired and done with it. His brother Daniel, a reporter, vanished while following the money behind an underground fighting circuit called the Meridian.

So Marcus comes back. Three chapters, three cities, three of the circuit's champions, and then the man who runs it. Twenty-two painted story panels, a passport that fills with stamps, and an ending you earn.

The Tokyo rooftop arena at night, neon skyline and wet concrete.

Chapter 1 · stamp 1 of 3

Tokyo

vs Ren "Switch" Sato

A rooftop above the city, rain on the concrete. Switch fights with nunchucks: long reach, fast hands, and big swings you can punish.

Story panel: Marcus arrives in Tokyo.
The São Paulo warehouse arena, painted murals and shipping containers.

Chapter 2 · stamp 2 of 3

São Paulo

vs Camila "Lock" Torres

A warehouse ring under work lights. Lock carries two tonfas and a counter that punishes anything careless. Bait it, then make her pay.

Story panel: Marcus arrives in São Paulo.
The Tangier hangar arena at sunset, a private jet behind the ring.

Chapter 3 · stamp 3 of 3

Tangier

vs Elias "The Broker" Voss

A hangar at sunset and the man who runs the Meridian. Voss mixes everything the first two taught you, and he saves his best for last.

Story panel: ring lights in Tangier.

{ core } · the rule that doesn't bend

Powerful moves create openings. Commit to the wrong one and you're punishable.

  • 60Every fight runs on a fixed 60-tick clock, the same on any screen.
  • 0No move can cancel its own recovery. Whiff, and the window is theirs.
  • 3Three moves can't be blocked. Jump them, or walk back out of range.

mod kit coming

Built to be remixed.

The plan is simple: we guard the rule above, and you get to change almost everything around it.

{ stays }

  • The combat rule: big moves open windows, and wrong commitments get punished.
  • Every attack has startup, active and recovery frames, and nothing cancels recovery.
  • The fixed 60-tick simulation, so a fight plays the same on any screen.

the rest / becomes yours

  • Fighters: new faces, new movesets, new specials.
  • Arenas: your city, your rooftop, your warehouse.
  • Stories: your own reason to get on the plane.

There's no mod kit or license yet. Follow along and you'll hear first: @kaseybuilds on TikTok.
