The world is opening their hearts and wallets to support the Japan relief efforts. The group over Valve and at Mann Co. is also helping out in their own way. The “Humanitarian’s Hachimaki” ($7.99), the “Benefactor’s Kanmuri” ($19.99) and the most prestigious “Magnanimous Monarch” ($99.99) will be available from now through April 6. Also available will be two limited edition noise makers, as if hearing mini guns and engineer’s beeping turrets aren’t enough. All DLC proceeds will go to the Japanese Relief Fund (net applicable taxes) and all hats can be equipped by all classes, but can’t be used in crafting nor can they be traded. For you tax conscious donations, unfortunately the Mann Co. can not be considered at tax write off.
