Transport-inators of Doooom!

 is a free, online Phineas and Ferb game on the Disney XD website. In it, the player controls Ferb and Agent P as they make their respective ways through 9 levels for each character that set inside the Doofenshmirtz Evil Incorporated building.

Prologue
Mom has left Phineas and Ferb a "huge list of chores" to do. In order to get the list completed faster, they decide to build teleporters. Meanwhile, Dr. Doofenshmirtz, looking for a Peglegged Hemisphingus to complete his Official Tri-State Area Bird Watching Sticker Book, notices the teleporters and zaps one with a Duplicat-inator to copy it just as Phineas is going through it, inadvertently teleporting Phineas into his building. Ferb grabs a plunger and follows after his brother.

After Tutorial Level
Agent P kicks his way through a window and into the DEI building, where Doofenshmirtz locks him inside a cage (which he is mass producing). He explains that the teleporters ("Transport-inators of Doom") will allow how to produce more evil inventions, which he calls "Evil 2.0." Perry puts his hand in a teleporter, his hand then comes out of another teleporter and grabs the key near it to free himself. Seeing Perry escape Doofenshmitz escapes through a teleporter with Perry in pursuit.

After Level 3
Phineas wonders seeing the cages that are platypus-size and continues to look for Ferb in the building while Ferb follows him a minute later. Meanwhile, Doofenshmirtz is angry that Agent P escapes his platypus-sized cage factory and decided to activate his Conveyor Belts of Chaos-inator.

After Level 6
Doofenshmirtz taunts Agent P that he's almost finish building 10,000 Transport-inators. Meanwhile, Phineas tries to look for a map that he presses a button at a computer terminal, activating the building's Freeze-inator freeze rays and setting off its intruder alert, causing Doofenshmirtz's security robots to capture Phineas and put him in a force field cage.

Level 9
Ferb successfully locates the three switches to reconstruct the bridge between Phineas's cage and the exit, disabling the cage and allowing he and his brother to successfully escape, although they do not see each other.

Level 10
Agent P overcomes Dr. Doofenshmirtz firing a Freeze-inator at him to first disable his two Transport-inator production lines, and then use a well-placed transport-inator to turn the Freeze-inator against Doofenshmirtz, freezing him and knocking him backwards into an infinite Transport-inator loop to defeat him and Evil 2.0.

Epilogue
Phineas and Ferb are reunited in their backyard, and Perry joins the boys shortly thereafter. Meanwhile, Dr. Doofenshmirtz is still stuck in the infinite loop, looking for someone to help him break it.

Gameplay
Ferb and Agent P control mostly the same with a few minor differences. The main difference is that Ferb can use his rocket boots to perform a double jump, while Agent P has a glider that allows him to glide. Along the way, each encounters a series of robotic enemies; cleaning robots require only one hit to defeat them, while security robots will charge when you get close to them and take two hits to defeat, while in level 7, it takes three hits to defeat the Hockey-inator robot. On each level, there are also anywhere from 100 to 400 gears or O.W.C.A. badges to collect, although it is not necessary to do so.

There are three types of power-ups in the game: a magnet that attracts nearby gears or badges towards you; a lightning bolt icon that turns Ferb or Agent P invincible and allows them to instantly defeat any enemies they touch; and a red stop sign, which stops all of the robots from moving for a limited time.

There are also several TV monitors that appear in both versions of each level. If you go near them, you will get a tip or a comment, and to listen to it again, press enter in front of it. For Ferb, the people on the monitor are Isabella, Ginger, and Milly. For Perry, Major Monogram and Dr. Doofenshmirtz will appear.

Background Information

 * Starting in late November 2010, the graphics of the game were given a special look for Christmas. Among the graphical additions include snow falling in the stages, Perry wearing a Santa Claus hat, and Ferb wearing reindeer antlers and a candy cane for a weapon. As of January 6, 2011, the holiday look disappeared, but is available by going to the setup menu and turning on "Holiday". The Holiday style was restored for December 2011.
 * Several of the elements of this game are similar to that of the popular video game Portal.
 * On level 9, it is possible for Ferb to jump onto the platform that Phineas is stuck on, though he does not acknowledge the fact that you are there.
