~Bonanza Bros~ A masterpiece of the 16-bit era that pioneered the later “stealth action” genre

• Bonanza Bros. is a 1990 Sega action game with a unique 3D-like visual style. Players control a thief duo to collect items within a time limit.

• The brothers ROBO and MOBO infiltrate "Bad Town" to find evidence of corruption. They take requests to clean up the crime-ridden city.

• ROBO is 1P in red, and MOBO is 2P in blue. Their geometric designs were inspired by the 1980s film The Blues Brothers.

• The game uses a split-screen for independent 2-player action. Players use stealth and knock out guards with doors or stun guns.

• In Japan, they are "chivalrous thieves," but in the West, they are "security testers". Overseas names were changed to Mike and Spike.

• Critics praised the "plastic look" visuals and innovative co-op gameplay. The jazz-funk soundtrack also received high acclaim.

• Some players found the jump mechanics heavy and imprecise. Others noted that the split-screen reduced visibility in single-player mode.

• The Mega Drive version removed stages like the "Department Store" due to limits. Infinite continues also made the game feel too easy.

• The duo appeared in the Tanto-R series and Sonic & SEGA All-Stars Racing. A secret command allows for invincibility.

• It is a pioneering stealth-action masterpiece that blends technical innovation with comedy. It remains a beloved symbol of Sega’s golden era.
