Ulduar is here, and Blizzard has released a new video you can watch above. We see new mobs and animations, get a look at Freya and some vehicle combat, and see some absolutely stunning interiors of the new raid zone.
The video lasts just under 2 minutes, and is worth your time to take a look. There is also some Blizzard music along with it, so be sure to have your sound turned up a bit. You can download high resolution versions of the video from Blizzard.
Perhaps the coolest thing in the video is around the 1:20 mark where we see a new tram style monorail (cue the Simpson's song). There are also very interesting stain glass like windows shown at the end.
Ulduar represents the latest in Blizzard's dungeon making and artistic design, and by the looks of it they're poised to create one helluva masterpiece.
