Q. What do I get if I paid for the game?
To thank you for your years of support, we will be giving players who have purchased TF2 a special Proof of Purchase hat to wear on any character in-game
Personally, I see this as an opportunity to get my friends that were too cheap into this (and destroy them in the process )
