The PlayStation 2 and Wii versions of the game combine third person shooter elements with brawlers. In this version, there is only one linear campaign, with factions changing between some levels. Their ability to transform into vehicles is absent, and is instead used as a power-up that instantly defeats all enemies around the player, and costs Energon, which is displayed in the HUD, underneath the health bar. Energon is earned from defeating enemies, and can also be used to restore health. There are also several unlockables, such as concept arts and character models, and a local co-op multiplayer mode, where two players have to survive against waves of enemies for as long as possible.
