The Australian Christmas 2011 update was a major content update for Team Fortress 2, released on December 15, 2011 Patch. Part 1 of the major update consisted of two item sets for the Pyro and Engineer, as well as a 'double drop week' lasting from December 15 until December 21, where the rate of drops through the item drop system was increased. It also included a new map, Foundry, as well as an achievement cosmetic, the Full Head of Steam. Part 2 added community-contributed items from the Steam Workshop, to only be obtained by unlocking a Nice Winter Crate with a Nice Winter Crate Key purchased from the Mann Co. Store. The Naughty Winter Crate contained a number of stock weapons with lights wrapped around them, including "Festive" as an added title, and required the separate Naughty Winter Crate Key to unlock. On the night of the 21st, all players were awarded a Spirit of Giving and all premium players received one free Secret Saxton. Less
