Valve has announced the second annual Christmas-themed update for free-to-play shooter Team Fortress 2.
The Australian Christmas update part two includes two retro-futuristic "Dr. Grordbort" class packs for the Engineer and Pyro, designed by Weta Workshop's Greg Broadmore.
It adds CP_Foundry, a new five-cap control point map designed by Valve's Team Fortress 2 team and featuring 12 map-specific achievements.
The update also adds 14 new Christmas-themed weapons, hats and items made by the Team Fortress community's item creators using the Steam Workshop.
For Christmas, Valve has knocked up to 75 per cent off over 50 items in the Mann Co. in-game store. This sale lasts until 2nd January 2012. Valve has also doubled the in-game item drop rate for the first week of the event.
