(Patapon 2. It has been revealed that it will host a four player (adhoc/gamesharing) multiplayer mode. the multiplayer mode stems from the single player mode, the former of which will involve giant eggs. These eggs are said to contain helpful items or smaller eggs. To hatch the eggs, four players must defend the egg on an enemy-laden multiplayer battleground, while moving it to a special egg-hatching altar. At this altar, all players must perform a hatching ceremony, which involves playing their rhythms in synchronization to crack the egg.)
Dear we need to have 2 PSP to hatch the egg
