November 4th is a very important day for Wallace and Gromit fans, and Telltale Games is celebrating their 20th anniversary in style.

From Nov 4 to the 8th you can download for FREE the PC version of the duo’s latest adventure, Muzzled! Help Wallace and Gromit stop con-man Monty Muzzle from making off with investment dollars meant for the dog shelter by signing up on the Wallace & Gromit site.

From today on, all four Wallace & Gromit’s Grand Adventure games are on Xbox Live. Each game costs 800 Microsoft points. There are also themes and gamerpics for you to check out.

You may also start ordering the Collector’s Edition DVD for PC as of today. The collector’s disc contains all four Grand Adventures episodes, behind the scenes video, game trailers and making of featurettes, and more from Aardman.

Most importantly, Telltale Games has joined forces with Child’s Play, and will be making donations to the charity based on every full PC copy of Wallace & Gromit’s Grand Adventures purchased between Nov 4th to the 8th. They will also be donating full copies of the games directly to the hospitals partnered with Child’s Play.
