Bonanza Bros.

In Bonanza Bros., Mobo and Robo accept a mysterious stranger’s challenge to retrieve hidden items from ten buildings in just three minutes. Security guards patrol each location and raise the alarm if the brothers are caught.

Choose either Mobo or Robo, use bullets to knock guards unconscious for a few seconds, and collect every treasure before escaping. An in-game map helps locate the objectives, while the time limit keeps each stage moving.

Bonus Stages

After every three buildings, a bonus stage challenges you to collect gold bars while avoiding three moving spotlights. Hiding behind open doors can help, and collecting all the bars awards 10,000 points. There are three bonus stages, each with a different layout.

Originally released in 1989, the game combines action, arcade, platforming, shooting, and puzzle elements.
