Play Greatest Heavyweights Online

Game Overview

Greatest Heavyweights is basically the Sega Genesis boxing game that actually makes you feel like you're in the ring—well, as much as a 16-bit console can manage. You've got all the legends here: Ali, Frazier, Holyfield, even Rocky Marciano, each with their own fighting style and signature taunts (Ali’s are especially cocky, obviously). The pseudo-3D view makes it feel a little more dynamic than your typical side-scroller, and the damage system is brutal—watch your fighter’s head or torso slowly grey out on the meter as you take hits, and if it fills up? One good punch and you’re done.

Career mode’s the real meat of it. You create a boxer from scratch, picking everything from stats to weirdly colored skin (green fighters, why not?), then grind your way up from the bottom of the rankings. Between fights, you’re juggling training minigames to boost your stats, which actually matters because the AI doesn’t mess around. Once you hit #1, the real challenge starts—the game throws all eight heavyweight champs at you, one after another. Good luck.

Fights are fast, the animations are smoother than Holyfield’s previous game, and yeah, Michael Buffer’s voice announcing "Let’s get ready to rumble!" never gets old. Just don’t stand around too long or the crowd starts booing. They want blood, and honestly? So do you.
