Last Bronx is a 3D fighting video game developed by Sega AM3 on the Sega Model 2 mainboard.

Each match is a best out of two rounds fight with victory by knock out or remaining health at the end of the 30-second time limit. The stages are set in real Tokyo city closed areas without any ring outs. However, fighters can jump on the barriers (and eventually make a disqualifying ring out backflip from there).

Sega AM3 used the "PKG" 3-button system introduced by the AM2 in Virtua Fighter – "P" stands for "Punch" (or weapon), "K" for "Kick" and "G" for "Guard".[7] The player uses the arcade joystick to move the character. Certain joystick and button combinations result in special attacks and combination attacks. The "G" button is used to block the opponent's attacks and to perform a feint attack called "Attack Cancel". Strong attacks, throws and rolling moves can be performed using different button combinations. Taunts can also be used – Last Bronx is part of the rare games in which the CPU uses this feature against the player or even another CPU controlled character.
