You enter the battle for the future of the world, where only the law of the jungle prevails. With each level, your character evolves, improving their weapons and shooting abilities. You start with simple throwable weapons and gradually learn to use tools that allow for different types of projectiles. A two-player mode is also available. The controls are very simple! Move your character with the control pad, aim the crosshair with the Wii remote, and shoot at your targets while dodging enemy attacks. If you're hit by an enemy bullet or come into contact with an opponent, it counts as an injury. Each injury costs you one heart on the display. Once you lose all your hearts, the game is over.
