Have a level 40 Zigfrak character with campaign completion? If so, you are cordially invited... to the Backyard BBQ Open Beta!
Visit the BBQ Beta sub-forum for all your Backyard BBQ needs.
To switch to the public test branch (Zigfrak 1.5), right-click on Zigfrak in your collection, and modify your opt-in status under the Betas tab. You may need to restart Steam to make sure it pulls down the right build. The download is about 260 megs, and the start screen says "Zigfrak v1.5.0".
