According to Adhesive Games, the open beta of Hawken will start on December 12th when the game will be made available worldwide, and you can try Hawken at that time if you want to. Checking their fuel levels, re-supplying their Tow Launchers and generally priming their engines, Adhesive Games has done all the preparation for the release of their upcoming Mech FPS, Hawken. Having had a successful few rounds of closed beta testing also boosted the open beta date. 
The term “Open Beta” has in recent years has in many cases unofficially marked the actual release of the game, with players able to start progressing without fears of further beta wipes. Hawken’s original release date was set for December 12th and now it seems the official launch will be delayed until early 2013.
The good news is Adhesive Games seems committed to staying in touch with the communities feedback. According to Hawken’s Lead animator Chris Lalli: “Open beta is our chance to implement all the good feedback we’ve gotten from closed beta players on the forums, and deliver the changes the community wants to see.”
