Transformers: Autobots is a video game made for the Nintendo DS by Vicarious Visions, and published by Activision on June 19, 2007, in North America, and July 20, that same year, in Europe, and uses multiple locations and items from the blockbuster Transformers movie directed by Michael Bay.
Transformers: Autobots is just one of the two versions of the game released for the DS, with the other focusing on the Decepticons, the antagonists of the whole universe, and sees some of the most iconic robots appear, including Bumblebee, Optimus Prime or Ironhide, who battle against their enemies, alongside humans and the US Army, in locations like the Hoover Dam, a Casino Strip or The Arctic.
The current unlockables and hints apply only for the Autobots version of Transformers for the DS, not for the Decepticons one.
HINTS
Spotting Decepticons
If you see a car which is a different color than usual, that could be a Decepticon. If it has its engine out in front of its front window, it definitely is a Decepticon. If you want to battle, transform and fight it.
Finding a Raider
Successfully complete all the Ice levels. Start the next level. Go to the police helicopters and police cars. Pause game play and select "Quit Mission." Find a circle of boxes, climb into it, then scan the car.
Police Brutality: Defeating the Boss
In the fight in the "Police Brutality" mission, if you are low on heath make a run for it in Vehicle mode. This also works in the Boss fight in "Know Thy Enemy."
GLITCHES
Fountain ramp
Go to the Tranquillity Museum with Create-a-bot using Hot Rodder form. Find the fountain and drive up to it slowly, facing east. When the front of the car is touching the fountain, stop, then press B + R. The car will boost off the fountain and fly high into the air. This requires practice, and will not work every time.
