Valve, the studio behind Team Fortress 2, is releasing three hats for purchase: The "Humanitarian's Hachimaki" ($7.99), the "Benefactor's Kanmuri" ($19.99) and the "Magnanimous Monarch" ($99.99). They will be available until April 6. All proceeds, says Valve, goes to Japan relief fund the Red Cross created, so feel good when you shell out for the Magnanimous Monarch headgear. [via TF2]
