Fast-paced and strategic, Fat Princess: Fistful of Cake pits two hordes of players against each other in a comic medieval battle on the PSP. The player's goal is to rescue a beloved princess from the enemy castle. There is a catch, though; the adversary has been feeding her magical cake to make her heavier to carry. Therefore, it will take much of the army working together to carry her across the battlefield. Team balance and strategy is crucial in Fat Princess: Fistful of Cake because players can switch between five different character classes, literally, at the drop of a hat.
