Details about the next game from the creative minds behind Call of Duty 4: Modern Warfare already leaked last week from an errant publication of an upcoming Game Informer issue.

But people all over got to see the thing in action as it closed out Microsoft’s Xbox E3 event this morning. Jetpacks, mechs and a voice that sounds a lot like Mr. Ubiquitous Troy Baker all whizzed by in the gameplay clip. It’s not until next year, meaning that there’ll be a lot more teasing and refinement to show before players will get their hands on it.
