DESCRIPTION: Bonanza Bros. is a side-scrolling stealth action game, with shooter and platform game elements. The players take the roles of one or both of the brothers Robo (1P, red) and Mobo (2P, blue) (Mike and Spike in some PAL versions), who may have been modeled on The Blues Brothers.[citation needed] The object of the game is to travel stealthily around each building while avoiding guards, retrieve several objects within a time limit, and move to the roof where a blimp is expecting the player with the loot. In this fashion the plot and gameplay resemble the Atari 2600 game Keystone Kapers, but with additional features similar to ones in Lock 'n' Chase. Two players can play cooperatively at the same time, as the screen is always split in two.
