Gangster Bros

About

Gangster Bros is a chaotic run-and-gun platformer where you control either Mario, Luigi, or Mr T. Each level is a gauntlet of enemies, explosive traps, and power-ups that let you blast your way forward. The controls lean into simple but frantic action, with shooting and jumping forming the core loop. Levels are short but packed with hazards, requiring quick reflexes to avoid getting taken out. You can play solo or team up, though the game’s focus stays on fast-paced combat over deep strategy. This Newgrounds classic has been played over 1.2 million times since 2009, with many praising its over-the-top energy. The mix of retro Mario visuals and sudden gunfights creates a quirky charm. While the gameplay is straightforward, the variety of weapons and traps keeps each run fresh. Some find the difficulty spikes jarring, but the retro appeal and absurd humor have kept it in rotation for browser game fans.
