Transformers: The Game is an action-adventure video game based on the 2007 film Transformers, developed by Traveller's Tales and published by Activision. The game closely follows the story of the film, depicting the Autobots and Decepticons' arrival on Earth following a war between them that has ravaged their home planet of Cybertron. While trying to conceal their existence from humanity, both factions search for a powerful artifact called the AllSpark, which could be used to restore Cybertron to its former glory, or to enslave Earth's population. The game features a split-campaign format, with players choosing to join either the Autobots or the Decepticons, and completing various missions for whichever faction they chose. A sequel, Transformers: Revenge of the Fallen, was released in June 2009, based on the film of the same name.
