Final Fight Game

The Final Fight game ” features a strong/fast/average character trinity that has been copied by later beat-em-ups (such as The Combatribes and Streets of Rage).” ScrewAttack takes a look back at this title after the break.

..the lead character Cody, is a martial artist who balances strength and speed and is the only character who stab enemies with knives at close range; Haggar, a former pro-wrestler, is very powerful yet slow and vulnerable to attack; Guy, a ninjutsu expert, is very agile, can hit and run, yet has weak offensive power.
