Real punches
Your phone camera recognizes your moves in real time: straight punches, hooks, uppercuts, kicks, side dodges and hands-up blocks. No controllers, no wearables.
Six heroes, six Ultimates
Light Lance, Thunderbolt, Gale, Fireball, Blizzard and Shockwave, each with its own follow-up effect: Burn, Shock, Freeze, Armor Break, Stun and Light Mark.
Giant kaiju
Rock, shell, pterosaur, mech and crystal core: five kaiju types take the stage, getting tougher as you go, with enrage mode and Ultimates of their own.
Fighting is exercise
Squat, jumping jack, high knees and burpee challenges pop up mid-fight. Finish one to counterattack or unleash your ultimate move.
