IGN now offers the promisedtrailer for Hawken, Adhesive Games' upcoming mech combat game. The clip highlights the game's story, but caps off with a little combat just for good measure, noting that this is still from a prototype, and is not reflective of the finished product. It also concludes showing a logo for DJ2 Entertainment, the company that that recently picked up the game's film rights.
There have been a bunch of mech games released over the past decade. Armored Core, Front Mission Evolved, Steel Battalion and Chromehounds come to mind. Granted, these were all Japanese (or Japanese-inspired) mech games but mech games nonetheless. Hawken doesn't really resemble traditional western mech games and looks to be a hybrid between Japanese and western styles.
