Transformers: War for Cybertron is a third-person shooter video game developed by High Moon Studios and published by Activision.
The game takes place on the planet Cybertron, prior to the Transformers arrival on Earth. The Autobots and Decepticons are engaged in a civil war. The game can be played starting from either faction’s perspective, but begins chronologically with the Decepticon campaign. The game revolves around the use of a substance known as Dark Energon, which the Decepticon leader Megatron believes will allow him to return the planet to what he refers to as a golden age.
