Wolfenstein: The New Order Steam pre-orders include Team Fortress 2 items
Wolfenstein: The New Order is responsible for the imminent arrival of yet more Team Fortress 2 items.
According to a post on Steam, pre-ordering Wolfenstein: The New Order will not only grant you access to the Doom beta but also some "exclusive Wolfenstein TF2 items".
The pre-order page reveals these items as "Die Regime-Panzerung" and "Der Maschinensoldaten-Helm".
That second one sounds like a hat, while the other may be some kind of weapon, going by the image below:
Wolfenstein: The New Order is due in May.
