It's no shame if you're not familiar with Hawken, it's a game in development by a small indie developer called Adhesive Games.

Also here's a vid that shows some desert combat and shows off the UI rather well.
So if you're interested in some multiplayer mech mayhem and supporting indie games, get yourself over to their closed beta sign up page.
