An evil megalomaniac named Kogg wants to destroy the planet. As everyone knows, destroying a planet can be a difficult task, so he enlists the skullmonkeys to help him. You must take control of Klayman, the only person who can stop Kogg's evil plan. You will travel through seven worlds comprised of more than 90 stages on your quest to save the world. In each level, you will have to face legions of Skullmonkeys, who can be defeated by jumping on their heads or by firing projectile weapons at them. To aid in the quest, there are several power-ups available, like Ma Birds (which act as checkpoints) and orange balls that will grant an extra life once 100 are collected. All of the world and characters are created using claymation figures and sculptures, so you can expect some pretty cool visuals. The fate of the planet is in your hands can you defeat Kogg and the SKULLMONKEYS?
