Valve has revealed that Portal fans will soon be able to get their hands on a very loveable plush Companion Cube. The Plush Weighted Companion Cube will be available alongside a rather fetching pair of cubes made for dangling on your rear-view mirror.

Valve has also announced that users should be prepared for a host of new homebrewed maps for Half-Life 2, Portal and Team Fortress 2. This is because the Source SDK has been updated with all the tools needed to create "custom game experiences for games in The Orange Box".

Expect more details on the Companion Cubes soon.
