Transformers: Revenge of the Fallen
Transformers: Revenge of the Fallen is set a few years after Megatron's defeat in the first game. The game is a linear third-person shooter in which the player takes control of many of the main characters from the movie and switches between the Autobots and Decepticons factions.
Story
The story is told in cutscenes, which also allow the player to easily switch from one character to another. The playable characters on the Autobots' side include: Optimus Prime, Iron Hide, Jetfire and Bumblebee. On the Decepticon side, playable characters include: Starscream, Sideways (a new character) and Megatron. Although the player can't transform wherever he wants, transformation has been introduced as a special attack in robot mode, as a fixed alternate game mode (driving through Shanghai tunnels as Sideways and flying through the skies of Russia as Starscream) and, in both robot and vehicle modes, as special moves that give the player alternate abilities. For example, if you transform as Starscream while flying, you can fly backwards as a robot to take out enemies behind the protagonist. In multiplayer mode, a friend can join in at any time during the single-player campaign as a "Remote Weapon System" to shoot enemies, create a shield, and transfer energy between both players.
