Choose one of five characters with different powers and get the bad guy who has infiltrated an amusement arcade. Fly into the machines and battle all the things found in a classic arcade: cocktails, uprights, printed circuit boards, pinballs, fruit machines, skill games and lots more.

The Sega Saturn version added an auto-bomber function that automatically uses bombs when hit by bullets, as well as original stages and additional playable characters.

In addition, a scene in which deformed characters perform skits between stages has been added.

These additional elements can be viewed by selecting "Arrange Mode" on the title screen.

You can also select the arcade version without the added elements, but the ending will be changed.

Genius Yamada, a mad scientist with a plan for world domination, has taken over a game machine at the You&Me Kamiyoga game center in Kamiyoga, Setagaya-ku, Tokyo, for starters.

Yuki Ito, a clerk at the game center, tries to solve the problem during her working hours by forcibly piecing together her own collection of game boards and asking the protagonists of each game to help her defeat Genius Yamada.
