I remember a flash game that I've been played repeatedly on Newsground when I was 12 years old but can't remember the name anymore.
It was created by a Chinese programer where you play as a white haired dude (possibly portraiting the creator ) in a green overall and fight in Street of Rage- like style a wave of enemies. With the money you win from the fight you can unlock melee weapons, firearms, perks and utilities. The antagonist consist of three peoples, a lanky long-haired guy with sunglasses, a Nemesis- like huge guy with a mini gun and a twin-tail haired girl who looks like Jinx on crack. Would be a pleasure if someone knows it name.
