Keroro Gunsou: MeroMero Battle Royale

Keroro insists he is still trying to conquer the planet, but seems more interested in building Gundam models than world domination, and fails miserably with every attempt. MeroMero Battle Royale is a multiplayer party fighting game similar to Power Stone, based on the popular anime and manga franchise known internationally as Sgt. Frog. Up to four players can play as one of twelve characters -- five of the frog-like invaders, five human characters, plus two hidden characters -- and duke it out in an overhead-view arena. Many items and weapons pop up during battles, which characters can grab and use against their opponents. One peculiar feature of the game is that everything takes place in a diorama, and each stage has two such arenas connected, which will switch depending on conditions in the battle. The game includes a Story Mode that follows specific characters and offers unlockable bonuses, a Free Mode where up to four players can duke it out on a stage of their choosing, and a Training Mode. There is also a gallery mode where unlockable illustrations, videos, and voice clips can be viewed.
