Taking place before the events featured in 2011's Transformers: Dark of the Moon movie, the video game tie-in introduces new characters as well as an all-new play mechanic. As players engage in giant robot battles on Earth, they will be able to activate a third conversion phase: stealth force. This transformation combines the firepower of robot mode with the agility and movement found in vehicle mode. Utilizing all three modes, you'll battle rival Transformers throughout multiple locales across the globe: from the jungles in South America to urban areas in Detroit to military compounds in Siberia. As with previous Transformers games on the DS handheld, two versions are available, each focusing on either the Autobots or Decepticons faction, which influences the types of characters you'll control. The bundled version includes a miniature car featuring the Decepticons logo. ~ Scott Alan Marriott, All Game Guide
