Phineas and Ferb: Across the 2nd Dimension
The story follows Phineas and Ferb as they navigate through various dimensions after being pursued by Normbots. The game fills in gaps from the movie, including references to episodes of the TV show not featured in the film. Players can co-op with a friend or play solo with a computer-controlled partner.
The gameplay is reminiscent of traditional platformers, featuring puzzles, mini-games, and boss battles between exploration and combat. Collecting items and unlocking special characters with unique abilities adds depth to the game. Characters can be switched in levels once more than two are unlocked, and customization options for weapons become available. Achievements and increased difficulty mode are also present, along with seasonal background props that change depending on the time of year.
This PSP title differs from other versions, such as the DS game with the same name, which has a distinct plot line, gameplay mechanics, and content.
