Overview and Gameplay
Mike and Spike infiltrate guarded buildings across Badville, collecting every piece of evidence before racing to the rooftop exit. This 1991 Sega Genesis conversion of Sega’s arcade game uses a permanent split-screen view, even in solo play, and lets characters move between the foreground and background of each corridor.
Ten missions introduce larger layouts, tougher guards, traps, noisy objects, and stricter routes. Players can stun ordinary guards, hide against walls, use doors as weapons, and approach shield guards from behind. Each operation has a three-minute limit, while collected evidence, enemy encounters, survival, and remaining lives contribute to the score.
Controls And Mechanics
- Directions: Move, change depth, climb stairs, or press against walls to hide.
- A or C: Jump.
- B: Fire the stun gun or open a door.
- Co-op: Two players control Mike and Spike simultaneously, splitting up to search different floors and reach the shared objective faster.
Version Notes
This English Rev B release was distributed for the USA, Europe, and Korea. North American materials call the heroes Mike and Spike and frame their mission as gathering evidence, while the game is also commonly titled Bonanza Bros. Rev B adds a TM symbol beneath the title-screen Sega logo.
