Free Wallace & Gromit episode and more for 20th anniversary of series

To celebrate the 20th anniversary of the Wallace & Gromit series, Telltale Games is offering Episode III of its Wallace & Gromit's Grand Adventures series, Muzzled!, for free! If you've been curious about how polite bumbling and cheese lust translate into game mechanics, now's your chance to find out. This offer applies to the PC version.

The company is also marking the auspicious occasion by discounting the full season of the PC version to $20 (from $35), releasing the whole set on Xbox Live Arcade, taking orders for a Collector's DVD, and participating in a charity drive with the Wallace & Gromit Children's Foundation and Penny Arcade (to which your full-season purchase will contribute). The discount and free game will only be available until November 8.
