Taking place before the events featured in 2011's Transformers: Dark of the Moon movie, the video game tie-in introduces characters such as Shockwave 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. In addition to the single-player campaign, Dark of the Moon also includes online multiplayer action across various game types.
