RPS Asks: Which festive updates are jingling your bells?

Having spent a LONG time yesterday explaining to Alice why jamming a Santa hat on a character does NOT an acceptable Christmas update make, I've decided to ask YOU:

Which games are doing holiday updates well this year?

"Well" could mean anything from creating a truly festive feel with their characters to doing something interesting/weird/subversive. In terms of cosmetics, we've been admiring the hardcore Santa paint jobs for American Truck Simulator - they're just over a quid - and the CS:GO chickens have been coaxed back into their festive wooly jumpers (green this year). If I were a Tracer player in Overwatch I could also be tempted to open a few winter loot boxes in search of her Elf outfit. But in terms of actual gameplay, we've been drowning in Advent Calendar entries and end-of-year fun so haven't had time for a good old pick through when it comes to holiday-related expansions/special game modes/new terrains etc etc!

So, go on - what's floating your Happy Holiday boat as we coast towards the end of 2016?
