The recently launched official Team Fortress 2 web site looks like it's going to be something a bit different than the normal marketing for a game title. The web site is giving folks a back door into the development process and one of the ways is showing off some unused artwork made for Valve's first person shooter.

The artwork comes in the form of trading cards that Valve team members designed near the end of Team Fortress 2's development. They never went into mass production but the web site is now showing off the designs for the cards. So far four have been revealed for the Engineer, the Demoman, the Heavy and the Medic. The other character classes will get their own trading cards and they will be revealed on the site in the coming weeks.
