Bonanza Bros. is a 1990 action-platformer developed by SEGA Enterprises for the Sega Genesis. Playing as the bumbling thieves Robo and Mobo, you must infiltrate heavily guarded buildings to collect valuable evidence and escape to the blimp waiting on the roof. The game features a distinctive split-screen perspective and a unique blend of stealth and shooting mechanics.

How to play

Navigate each building to collect all designated items before time runs out, then head to the roof exit. Use walls and background objects to hide from patrolling guards, and utilize your stun gun to temporarily incapacitate enemies.

Tips

Flattening yourself against a wall is crucial; guards cannot spot you when you are hidden, even if they walk past.
You can squish guards behind doors by opening the door right as they pass.
Your stun gun only incapacitates guards temporarily, so run past them quickly before they recover.
