Sim: Heavyweight Boxing Champion

Choose Your Era — 1880 to 2026+
Start your career in any year from the bare-knuckle age of the 1880s to the modern mega-fight era and beyond. The game world evolves authentically with the times — title fight rounds change from 25 to 20 to 15 to 12 as the sport modernises, sanctioning bodies appear in their real years (one world title until 1963, then WBC, IBF in 1983, and WBO in 1988), venues shift from Yankee Stadium and the Polo Grounds to Caesars Palace and Riyadh's Kingdom Arena, fighter nationalities reflect each era's talent pools, and purse money grows from thousands to tens of millions. Boxing news announces every historic rule change as it happens.
Play As A Legend
Don't just fight alongside the greats — become one. Choose from the 300 greatest heavyweights of all time and relive their careers from the beginning. Each legend starts with their authentic overall rating, real fighting style, true hometown, and the exact age they turned professional. Take Iron Mike Tyson from his 1984 debut as a wrecking machine, or step in as Muhammad Ali — turning pro at 18 in 1960 as the reigning Olympic gold medallist. Then rewrite history: drop any legend into a different era and see how they'd fare against the champions of another age. Start fresh at 0-0 and build their legacy your way.
2,500+ Real Heavyweight Fighters
Ali, Tyson, Foreman, Frazier, Louis, Dempsey, Lennox Lewis, Holyfield, Holmes, Marciano, Klitschko, Fury, Usyk, Joshua, Wilder, Jack Johnson, Jim Jeffries, Bob Fitzsimmons, and over two thousand more. Every significant heavyweight from 1880 to 2026 and beyond (upcoming top-rated amateurs) is in the game with authentic ratings, fighting styles, stances, and nicknames. Start in their era and share the ring with the greats — or begin in a different decade and watch them emerge as young prospects turning professional.
Your Journey to the Top Starts Here
Start as an unknown amateur and fight your way through a living, breathing heavyweight division of 500 unique boxers at any one time. Every fighter has their own record, style, strengths, weaknesses, and personality. Choose your fighting style, pick your stance, and begin the long climb from unranked nobody to undisputed world champion.
Live Round-by-Round Fight Commentary
Every fight unfolds in real time with rich, detailed commentary that makes you feel ringside. Choose your strategy before each round — box from range, apply pressure, fight on the inside, or go for the knockout. Watch stamina drain, cuts open, swelling develop, and momentum swing round by round. Legendary fighters even bring their signature moves to the ring — see the Ali Shuffle and the Dempsey Roll light up the commentary. Judges score independently with realistic split decisions, majority decisions, and controversial verdicts. No two fights ever play out the same way.
A Title for Every Era
In the early eras, there's one heavyweight champion of the world — winning that single belt makes you the champion, undisputed by definition. From 1963 onwards, sanctioning bodies fragment the picture: the WBC arrives, then the IBF in 1983, then the WBO in 1988. By the modern era, four world titles sit at the top of the mountain.
Regional titles emerge in their own historical order as stepping stones for rising contenders. The British title (1891) is the oldest, followed by the European (1946), Oriental and Pacific (1952), Commonwealth (1954), North American (1969), African (1973), and Pan Asian (1995). Hold all four world belts simultaneously and become the undisputed heavyweight champion of the world.
A Living, Breathing Division
This is not a static roster. The heavyweight division evolves every month. Fighters age, decline, and retire. New prospects turn professional from the amateur ranks. Champions rise and fall. Mandatory challengers are ordered. Title fights are scheduled, cancelled, and rescheduled. Sons of legendary fighters emerge carrying their father's surname and a genetic edge. The division has a life of its own — and you are part of it.
Authentic Fighters, Authentic Identities
The legends fight like themselves. The biggest punchers in history carry power and killer-instinct ratings true to their real careers, so the sluggers hit like sluggers and the slick boxers box. Authentic nicknames appear throughout the game — across rankings, fight cards, results, news, and profiles. Square off against "Iron" Mike Tyson, Tyson "The Gypsy King" Fury, "The Brockton Blockbuster" Rocky Marciano, and hundreds more. Fighters carry their real hometowns, and amateur honours like Olympic gold medals are recorded in their biographies.
Rivalries That Write Themselves
Rivalries form naturally through close fights, controversial decisions, callouts, and press conference confrontations. Your rivals will call you out in the media, demand rematches, and fuel grudge matches that the whole division watches. Some rivalries last an entire career.
Deep Career Management
Every decision matters. Choose your opponents carefully — fight too far above your level and you risk a devastating loss; stay too safe and you will never climb the rankings. Before every fight, select a training camp — Power, Speed, Defence, Cardio, Technical, or Brawler — each with genuine tradeoffs that shape how your fighter performs on the night. Manage your fighter's age, energy, and physical condition across a career that can span over a decade. Purses grow from thousands to millions as your reputation builds. Watch your social media following explode as you become a household name — or build your fanbase the old-fashioned way in the pre-internet eras.
Annual Awards and Recognition
At the end of every year, the boxing world hands out its awards. Fighter of the Year, Young Fighter of the Year, Fight of the Year, Knockout of the Year, Upset of the Year, and Comeback Fighter of the Year — each with a detailed writeup that captures the story of the season. Win them and cement your legacy. Watch them go to your rivals and fuel your motivation.
Complete Fight Records and Statistics
Every fighter in the division has a full BoxRec-style record with detailed fight history, opponent records, methods of victory, venues, and purses. Active fighters retain their full pro fight history with no cap, so every bout is documented. Your own career page tracks everything from knockouts and win streaks to earnings and title defences. The all-time records page celebrates legends past and present — most career wins, longest title reign, oldest first-time champion, retired with fewest defeats, and many more.
Watch the Division Unfold
You are not the only story. Watch title fights play out with full commentary. Follow the rise of young contenders. Track who holds each belt. Read the boxing news that covers every major result, upset, and title change in the division. The heavyweight landscape is always shifting.
Olympic and World Amateur Championships
The amateur scene runs in parallel with the professional division. Olympic Games every four years and World Amateur Championships every two years produce medal winners who turn professional and enter the rankings. Olympic gold medalists arrive as elite-tier prospects, with appropriate floors for silver and bronze — and their medal honours follow them into their professional biographies. Some of them may become your greatest rivals.
Hall of Fame and Legacy
When the time comes to hang up the gloves, retire and see how your career measures up. Your record, titles won, title defences, earnings, and achievements are preserved in the Hall of Fame. Then start again — create a new fighter in the same universe and enter an evolved division where the legends you fought alongside are now retired icons.
Built for Replayability
No two careers play out the same way. Eight fighting styles, multiple stances, adjustable difficulty, 300 playable legends, and a division that generates its own drama ensure that every playthrough tells a different story. Generate up to 1,000+ years of heavyweight history and watch dynasties rise and fall.
