About This Game

Turn your enemy’s strike into your opening.

IAI//BREAKER is a bullet-hell swordfighting action game where iaido slashes send enemy bullets flying back. Wield your blade with the mouse and face ten formidable foes.

Press the attack or hold your ground?

Deflect incoming bullets to recover energy, or sheathe your blade and strike with a sweeping draw slash. With limited energy, every counterattack is a choice.

Turn danger into a counterstrike.

Use Focus to slow the bullets and read their paths. Even an attack that breaks through ordinary defense can become a powerful counter when caught at the center of your blade.

Read. Break. Overcome.

Wear down your foe with returned bullets, then follow up when their guard breaks. Learn each opponent’s patterns and timing, and master the decisive strike.



Choose your challenge across three difficulty levels.
