Valve is going to put Team Fortress 2’s fanbase to work, giving them the chance to craft their own in-game items, weapons and avatars.
It’s part of the new "Contribute" site, which will allow TF2 fans to submit their own ideas for things like hats and guns to Valve. The good ones will be included in the game. For everybody, too, not just the person responsible.
You can submit stuff right now, gallery coming soon.
