Exclusive Team Fortress 2 Chess Set - Red VS Blue by ThinkGeek It's chess, as fought by the RED and the BLU of Team Fortress 2. Hats can be swapped for crazy added gameplay. Includes some DLC for TF2: the Grandmaster Hat. Unlike other hats, this one actually changes. It starts as a Pawn and levels up or down (through the chess pieces) correlating to your kill streak. From WizKids Games. Fully-licensed Team Fortress 2 collectible game thing.
