A companion to Transformers: War for Cybertron, the Wii's Cybertron Adventures is a combination rail-shooter + driving game rather than a third-person shooter.
From the publisher:
* Battle as the AUTOBOTS and DECEPTICONS through two unique campaigns
* Original Missions designed exclusively for the Wii tell the untold story of Cybertron
* Team up with a friend in two player co-op to dominate the battlefield
