Build a fighter, work the circuit, and put your mark on the world before anyone else. The amateurs are waiting, and the WFL is watching.
A new contender walks in off the street. What happens next is up to you.
Glass Jaw is a retro MMA career sim you play as the manager. Create a fighter, work the circuit, and climb from the amateurs to a world title in one shared, always-on world where the other corners are real managers and every card actually happens, live.
FIGHT NIGHT NEVER STOPS
Four live cards a day: morning card to after-hours. Book a bout, walk to the cage, and follow the round-by-round call as it streams in real time. Between rounds you work the corner. Read the fight, switch your game plan, dial the aggression from CAUTIOUS to ALL-OUT, and answer the bell.
BUILD THE FIGHTER
Create your fighter from eight fighting styles across eight weight classes. Boxer, Kickboxer, Muay Thai, Karate, Wrestler, Brazilian Jiu-Jitsu, Sambo, and Well-Rounded. Shape their look with an avatar, then develop them for real by assigning attributes, skills, and a technique kit of 33 named moves you learn, sharpen, and master.
WORK THE CIRCUIT
Every career starts on the amateur circuit and earns its way up: AMATEUR → REGIONAL PRO → THE WFL, the big show of the World Fighting League. Chase rankings, call out rivals (or duck them), sign the open contract when you just want a fight, and force your way into title contention. Belts are defended in public, on live cards, against whoever earned the shot.
RUN THE STABLE
Manage multiple careers at once. Negotiate call-ups, bank purses and win bonuses, spend on recovery, and decide who fights tonight. When a career ends, your record and legacy grade are immortalized.
START A FIGHT CAMP
Sign with a fight camp for better training and corner boosts, pay your dues, and build the war chest or charter your own camp, set the dues, recruit a roster, and put your name on the sign.
A WORLD THAT KEEPS SCORE
Cards run in 34 host cities with authored venues, crowds, and gates. Headlines get written, KO / FIGHT / SUB OF THE NIGHT hardware gets handed out, rankings reshuffle after every card.
DAMAGE IS PERMANENT
Wars leave marks. Chins crack. Every fight is a bet of long-term durability against short-term glory and knowing when to retire a legend is part of the job.
THE HOUSE RULE
Gold speeds up time by finishing a training session, accelerating a camp, buying back recovery. It never buys a win.
Add the Fight Night widget to your home screen, keep an eye on your booked bouts, and be there when your fighter makes the walk.
The bell doesn't wait. Answer it.
Advanced saved fight strategies, cosmetic backgrounds on fight tape, the Mexico flag cosmetic, and reliability improvements.
