Iron Circuit is a free online fighting game that runs in your browser. It has an overworld you walk, fifteen towns to reach, and a full side-on fight — with a ground game underneath it — every time somebody squares up.
The road between towns is four shades of green, the way a handheld screen used to be. You walk it, knock on doors, talk to people who are not going anywhere, and take the flatbed when the walking gets long.
Then somebody squares up, and the whole thing changes colour.


You do not start with a moveset. You start with hands. Sweeps, dashes, throws, armour, counters, the surge arts — every one of them is locked until you meet the fighter who built their whole game around it and take it off them. Your list of moves is a list of people you have beaten.
Spread down one road, each with their own stats, look and habits.
Doors you can walk into, people who talk back, and a flatbed for fast travel.
Bare hands upward. Switch mid-fight if you have earned the option.
Handheld green on the road, arcade cabinet the moment it kicks off.

Most browser fighters stop at punch and kick. This one takes it down: position matters, being underneath is its own problem, and there is a clock on how long you are stuck there. Hammerfist, ground elbow, kimura, armbar, choke — and a scramble back to your feet if you can earn it.
A controller works too — plug one in and press A, or pick it on the first screen. The game tells you every button it has on the panel under the screen, including the ones you have not unlocked yet.
Touch controls appear on their own, and change with what you are doing: a stick and talk out on the road, the full striking set in a fight, and the submissions when it goes to the floor. Turn the phone sideways and the picture fills the screen.
Yes. It is a free online fighting game that runs in your browser with no download, no account and no purchases. Your progress saves to your own device.
You learn a move by losing to it first. Every move belongs to a fighter somewhere on the road, and beating that fighter is what teaches it to you. There is no shop and no skill tree, so your moveset ends up being a list of people you have beaten.
Crouch first, then press the low kick. Holding down turns the low kick into a sweep, which puts the opponent on the floor and goes under a standing block. You unlock it by beating Sensei Okada.
Fights can go to the floor. Down there you have five moves — hammerfist, ground elbow, kimura, armbar and choke — and an escape meter that takes five seconds to fill before you can stand. Land three hits from the bottom and you reverse the position.
Fifteen towns on the road plus three places past it, and 94 fighters in total.
Yes. On a touch device the game shows a number-pad control layout that mirrors the keyboard, and only the moves you have actually unlocked appear on it. It also supports a gamepad.
