Transformers : La Guerre pour Cybertron - Decepticons

Set on the Transformers' home planet of Cybertron, Transformers: The War for Cybertron tells the story of the Transformers long before they ever made contact with Earth. In Transformers: War for Cybertron - Decepticons, players can play as their favorite Decepticon characters and fight as the ultimate weapon, transforming at a moment's notice between vehicle and robot and striking enemies with devastating firepower.

As in the console version, there is a linear campaign of missions, which more or less follow the same story.
There is also an Arena mode with five "arenas", each with six available missions, four bonus levels from the opposing game, and seven multiplayer levels.
