The Heavy Update, officially known as A Heavy Update, was the third major content update for Team Fortress 2. The focus of the update was the Heavy class. As was customary, three new weapons for the class were revealed, and the slowdown mechanic was introduced. To accompany the Sandvich consumable weapon, Meet the Sandvich was released alongside the update. A new game mode, Arena, was introduced. It focused on combat between the two teams and brought five new maps to the game. Two other maps, Badwater Basin and Steel, were also included. The update was released with the August 19, 2008 Patch.
