— The Soldier turning down a game
The Grandmaster is a promotional headwear item for all classes. It is a team-colored hard hat, with a small chess board attached by a rubber spring and two strips of rubber, which bounce around as the player moves. On top of the chess board, a small device projects a small red bomb hologram on the RED team, and a blue wrench hologram on the BLU team, both of which rotate. As the player's killstreak rises, the hologram projection changes to various chess pieces.
