We've had it every year since 4 years in our servers during xmas.
It looks actually much better in server than on screenshots.
There are quite a lot of decorations such as xmaslights and gifts here and there.
Eventhoght it may be bright map, it really gives a good feeling and with right company it's a great gameplay.
Also that is not posted here, there is a "bridge" kind of thing where the tank stops between allies commandpost and depot wall or how ever its called.
I'll add some "bad" screenshot that I've taken.
