— The Sniper on finding precious treasures
The Bounty Hat is a promotional headwear item, wearable by all classes. It is a worn-out tricorne hat topped with a closed treasure chest.
The Bounty Hat was awarded to players that completed 5 out of 28 objectives in The Great Steam Treasure Hunt. Users who completed the requisite number of Treasure Hunt objectives were required to visit the promotion page and click the "Unlock Hat" button in order to have the hat added to their backpack. When the user obtained 15 Treasure Hunt achievements, the Bounty Hat could be upgraded to the Treasure Hat.
December 7, 2010 Patch
- The Bounty Hat was added to the game.
- When showing the Bounty Hat on the loadout screen, the bottom half of the hat disappears, replaced with the background color.
- On rare occasions, when equipped, the Bounty Hat appears to be cloaked.
- In some cases on the loadout screen the Bounty Hat will appear twice resulting in 2 Bounty Hats clipped into eachother, one slightly offset from the other.
