From Wikipedia: Transformers Decepticons is an action-adventure video game based on the 2007 live action film Transformers.[1] It is the Nintendo DS port of Transformers: The Game, but follows a different storyline and focuses exclusively on the Decepticons. It was developed by Vicarious Visions alongside Transformers Autobots, which follows the Autobots; the two games share some basic similarities, but overall feature different characters, missions and locations.[2] Both games were published by Activision in June 2007, and received mixed reviews.
