When Revenge of the Fallen lands in your hands, you'll be able to take up arms as either the Earth-protecting Autobots or the cranky and destructive Decepticons in a cast of characters Activision is calling "the largest, most diverse range of playable Transformers."

Each of those 'bots will pack specific abilities and weaponry. On their way to places such as Cairo and Shanghai, players will be able to switch instantly between their Transformers vehicle and biped forms and be able to take the action online and battle other players in new multiplayer modes.
