We never quite covered box art like we did for Left 4 Dead with any other game.  Whether it was German censoring or hand puns, we felt the need to tell the world about the box art for this four player co-op title.  Now several months later, as Valve gears of for some DLC, they've revealed the original evolution of the box art. 

We were a bit surprised to see the familiar hand was no where to be found in any of the original mock-ups; and in fact the coloring was completely different.  Jeremy Bennet, the artist for Valve in charge of making these, explains why the shift went from a focus on the characters to something slightly different in the latest blog post.
