Bonanza Bros — About this game
Enter guarded buildings to gather the marked loot before time runs out. Floors, stairs and doors let you plan a route around patrols; a shot only knocks a guard out temporarily. Collect everything required and head for the escape point. Unlike the split-screen Mega Drive game, this Master System adaptation is a solo outing.
