Vanessa, a member of NEST, and Bumblebee have been assigned to guard a strange device that belongs to a civilian named Jay. However, the Decepticons, lead by Megatron himself, attack and steal the device. A team of humans and Autobots, the Human Alliance, is sent out to stop Megatron’s plan. Sega’s action adventure game, Transformers Human Alliance, partners up to two players with one of three of the movie’s stars, Optimus Prime, Bumblebee or Sideswipe. Players must battle their way across America, Africa and Europe destroying the Decepticons before they find the All Spark, a material capable of bringing any mechanical or electronic object to life.
