The mech shooter Hawken has spent a long while in closed beta, but all of that is set to change tomorrow. The open beta is just around the corner, and Adhesive Games has released a new trailer to celebrate the impending bundle of mechanized joy.

The cinematic scene takes a cutaway view of Hawken's enormous walking tanks, showing some of the grinding gears and pistons at play. You can still sign up for a free beta account at the official site, and claim your call sign before the veil on the game lifts tomorrow. Check out the trailer below.
