Achievement items are unique items, weapons, misc, action items and hats, that can be obtained via the completion of achievements in Team Fortress 2. Each individual class has 3 Milestone achievements. Completing each Milestone will grant the player a specific weapon for that class. Other achievements award items to players for completing other tasks, such as defeating bosses. Items earned via achievements can not be traded.
