Disney Interactive Studios. Based on the Disney cartoon -- specifically an upcoming original movie -- Phineas and Ferb: Across the 2nd Dimension will feature the TV voice talent of the principal characters, including Phineas and Ferb.
The PS3 and Wii versions include ten playable characters and two-player cooperative play. The PS3 version also features PlayStation Move compatibility. All versions of the game also include a secret agent platypus, making this probably the coolest sentence we've ever written.
