A prematurely leaked, and in the meantime taken down, listing on Xbox Live revealed an upcoming DLC with four new maps (thanks TFormers).

Become the ultimate weapon and wage war in four new maps – engage in multiplayer combat in HAVOC and FORTRESS or fend off waves of Autobots in DISTRICT, and Decepticons in FORSAKEN, two new Escalation mode maps. Also gain access to 5 characters and their chassis for use in Escalation mode and Multiplayer character creation; SCATTERSHOT, ONSLAUGHT, DEMOLISHOR, SHOCKWAVE and JAZZ are ready for battle. Fight to the end in the war that started it all!

Transformers: War for Cybertron features two distinct storylines: the Autobot campaign tells a story of heroism to save their home planet against overwhelming odds, and the Decepticon campaign tells a story of an unquenchable thirst for power to control the universe.

Transformers: War for Cybertron challenges players to become the ultimate weapon as a Transformers character in the final, epic war that will determine the survival of their entire race.  Armed with a diverse arsenal of lethal, high-tech weaponry and the ability to instantly convert from robot to vehicle at any time, players will engage in heart-pounding battles on land and in the air in this gripping, 3rd person action shooter set in the Transformers' war-ravaged homeland.  Complete with several multiplayer modes, Transformers: War for Cybertron allows gamers to play through story missions with their friends in drop in/drop out online co-op, and also create their own Transformers character for competitive head-to-head multiplayer modes, choosing among four distinct character classes, personalizing its look and selecting from a huge variety of weapons, skills and abilities.

The game features a sci-fi art style that introduces to fans the entire living, metallic world of Cybertron, as well as all-new visualizations of the iconic Transformers characters in their original Cybertronian forms.
