In Transformers: War for Cybertron, you take control of the classic G1 Autobots and Decepticons as they fight for control of planet Cybertron. Set millions of years in the past, War for Cybertron offers up an alternate retelling of the Transformers' origin in both an Autobot and a Decepticon campaign. Before the start of each mission you can choose from one of three classic Transformers characters to play as. Once you are done with the single-player you can hop online to play a variety of competitive multiplayer modes with your own customized Transformer and rank up to unlock new abilities. If you prefer to play cooperatively instead of competitively there is also 3-player online co-op for the entirety of the campaign as well the Firefight-like mode known as Escalation, where up to four people hold off successive waves of enemies.
