Co-op Play

Co-op Play is a mode in Super Monkey Ball: Step & Roll. In it, a second player points at the screen to aim a reticle at obstacles, and shoot them to damage and destroy them.

Gameplay

Player one controls the game as usual. Player two points at the screen to aim a retical at obstacles. The retical turns red when aiming at an obstacle that can be destroyed. Obstacles may take 1-6 shots to destroy depending on the obstacle, or may require to be shot in a specific location. Firing at obstacles consumes ammunition, but ammo can be replenished by shaking the Wii remote.

This game mode is played on the same stages as single player mode, but with the layout of obstacles being different, usually either containing more obstacles, or obstacles in more disruptive locations, often blocking the player's path and requiring player two to shoot them to progress. Different guns can be picked up by the player, or shot by player two, to be equipped, and have different amounts of ammo and different effects. The gun type resets to the default at the start of each new level, or when respawning from a fall out.

Weapons

There are 3 weapon types:

• A standard green gun, which has 9 ammo and no special properties
• A red rocket launcher gun, which has 30 ammo and fires explosive rounds which do triple damage and can hit multiple obstacles at once. However, it also destroys bananas.
• A blue laser gun, which has 30 ammo and fires lasers which can pierce through obstacles and hit multiple obstacles in a line.
