A YouTube user has uploaded the first teaser for Battlefield 3's newest expansion, End Game. Among other things, the trailer features players chasing each other on dirt bikes, dodging helicopter fire with a dirt bike, and detonating explosives... while on a dirt bike. Dirt bikes!

End Game is scheduled to arrive March next year.
