Australian Christmas 2011
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 is increased. It also included the new map, Foundry, as well as an achievement cosmetic, Full Head Of Steam.
Part 2 added community-contributed items from the Steam Workshop, to only be obtained by unlocking Nice Winter Mann Co. Supply Crates through keys 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.
