You are a member of the International Alliance, a global group of super-powered heroes that fight the Kraken organization.

The task force consists of you, a.k.a. Leo, and several other heroes. Your mission is to stop the evil Kraken and destroy their base.

As you progress through the game, you will unlock more abilities and weapons to help you fight the monsters.

The monsters include several different types of enemies. You will have to dodge, blast, and out-maneuver them to survive. The monsters will also become more powerful and more difficult to fight as you go deeper into the game.

As you fight the monsters, you can earn a game cartridge that you can use to unlock the Arcade Room.
