Proof of Purchase
The Proof of Purchase is a cosmetic item for all classes. It is an olive green Brodie helmet with slight battle damage, two faded stripes down the middle, and a Team Fortress 2 logo of a slightly darker shade emblazoned on the side. A narrow belt with a gold buckle extends around the back, over the wearer's neck.
This hat was initially given to players who purchased Team Fortress 2 before the Über Update on June 23, 2011, but can still be obtained by receiving a gift of the game, or by activating a retail copy of the game, such as purchasing the Orange Box or Valve Complete Pack.
- The Proof of Purchase was added to the game.
- Fixed the Proof of Purchase not being able to be used in the Rebuild Headgear recipe.
- The description references the hat's origins. The hat itself is visible on the Human player model from the early "Invasion" version of Team Fortress 2, as well as the files that were leaked in 2003 with Half-Life 2's source code.
