About this game
Mobo and Robo Bonanza are enjoying their favorite television show when the picture crackles and a shadowy figure of a mysterious stranger appears on screen.
This figure asks them to collect certain items that he has placed inside various buildings to test his security force.

If they return the items successfully, Mobo and Robo will be rewarded.
The two of them state that they will get the job done in just three minutes.
However, little do they know that each building is packed with security guards who will raise the alarm if they are caught red-handed.
Fortunately both Mobo and Robo are equipped with bullets that can knock the guards unconscious for a few seconds.
An $100 reward will be given out if Mobo and Robo are apprehended.
As either Mobo or Robo, you must collect all the treasures before leaving the ten buildings and shoot any security guards that get in your way.
Remember that you are under a time limit.
An in-game map will help you locate the treasures.
There is a bonus stage after three buildings, where the object is to collect the gold bars in a limited amount of time without one of the three spotlights shining on you.
If it is possible, hide behind open doors.
If you manage to get all the gold bars, 10,000 points is added to your score.
There are three of these bonus stages, but each of them varies.
About Sega Genesis
Known as the Mega Drive outside North America, the Sega Genesis (1988/1989) was Sega's most successful console and Sonic the Hedgehog's original home, fueling the "console wars" era against Nintendo's SNES. Genesis cartridge collecting is well-established: common sports and platformer titles are affordable, while sports-license and later-era games with smaller print runs can carry a meaningful premium.
