Someone was able to get their hands on an early copy of the next Gameinformer magazine which reveals what Metroplex looks like and it talks about Escalation, which will indeed return for the War for Cybertron sequel. This bit of news comes just before E3, where High Moon Studios was expected to release this information.
Metroplex appears in the Optimus Prime level and while you are unable to control him directly, you can mark targets for him to destroy while playing as Optimus. It looks like Escalation has changed slightly, but that's really all we know at this point. By the time this edition of Gameinformer hits the shelves, the Gameinformer website will give us a first look at some of the Escalation website.
Stick around for more Fall of Cybertron news during E3 this week.
