Upcoming multiplayer shooter Hawken, which just looks fucking cool, doesn't have a singleplayer campaign. So it doesn't really have much of a story. What it does have, though, is a filthy dirty megalopolis/anime setting, which this moody new trailer shows off.
There's also some gameplay footage at the end, if all you're here for is more shots of mecha blowing the crap out of each other.
Hawken, the work of nine men, is one of the big surprises of 2011, coming out of nowhere and landing a prominent spot on many people's "must see MORE" lists.
