Patapon 2 is a direct sequel to the game Patapon. The tiny eyeball warriors return in their quest to find "IT" at Earthend. To help them in their various ordeals, the player once again takes on the role of "The Mighty One" or "Mighty Patapon", who leads them by playing the sacred Pata, Pon, Chaka and Don drums following the game BGM's beat. Different combinations mean different orders that the Patapons follow.
The game itself is a succession of levels accessed from Patapolis, most of which are repeatable, but increase in difficulty each time. The player must use their skills and knowledge to overcome challenges and defeat enemies.
A new ally joins the Patapon party, the Hero Patapon, who can be of any type of Patapon available in the game, if they are unlocked. The hero has the same stats as other Patapons, but can have different attributes, depending on which kind of mask he is wearing. He also has different special abilities fitting the type of Patapon he is set to.
The game features new minigames and various features added to those taken from the first game, including an evolution tree, in which every Patapon can change his appearance, level up, and gain different properties.
Multiple players can now play together via the Patagate Shrine, using their unique customized Hero Patapon to defeat Giant Bosses and destroy enemy fortresses. Doing so yields treasures such as new masks for the Hero to wear, Komupons (Hero Patapon NPC'S), various materials, and equipment.
Patapon 2 was released on May 5th, 2009 in North America for the PSP console.
