Bonanza Bros. is a 1990 Sega arcade game in which two brothers, Robo and Mobo, infiltrate buildings full of guards to steal valuables, in an isometric perspective that favors route planning and stealth over direct confrontation: guards can be stunned but not permanently eliminated. It was designed for two players, with each controlling one of the brothers.
It's one of the most original offerings in Sega's catalog of the time, with a lighthearted tone and an infiltration mechanic uncommon for arcades back then. It holds up well today as a piece of clever design, distinct from the pure action that dominated arcades in those years.
