There's no such thing as just an ordinary day during Phineas and Ferb's last week of summer vacation.
There's a whole lot of stuff to do during the last week of summer vacation, and of course Phineas and Ferb want to do it all. Join the charismatic brothers of invention as they travel to out-of-this-world places in their newest invention, the A.T.T. (All-Terrain Transformatron). This upgradeable, customizable, ultra-cool amphibious ride helps the boys in their search for artifacts to stock their Museum of Cool. Meanwhile, bumbling villain Dr. Doofenshmirtz unleashes his latest obscure "-inator" devices to further his plot to take over the entire Tri-State Area.
Play as Phineas, Ferb, or Perry the pet platypus (aka double Agent P) in four intertwining episodes. Along the way you'll meet and interact with characters from the show including Candace, Isabella, Buford, and whiz-kid Baljeet.
Infiltrate the Doctor's lab as Agent P and jump, run, crouch, slide, hang from ledges, fight robotinators, and sneak past traps and obstacles.
Upgrade the A.T.T. by assembling new parts like pinchers, drills, rocket boosters, and headlights to access new areas. Customize the A.T.T. as you like with colors, sounds, and decorative parts.
Fight flying Norm Bots and robot hordes including the Patroller, Jumper, Charger, and other “get-rid-of-cool-stuff-inators.” Avoid Dr. Doof’s nasty lab traps: collapsing floors, laser beams, and falling boulders.
