It turns out Ordrak is still a problem in Torchlight II even after he's dead. Like most fantasy villains, death is not really an issue for him.
This trailer shows three heroes trying to kill him yet again, after the events in Torchlight. It doesn't show off any new gameplay, and the story is not necessarily that important in a game like this, but it's still a really fun trailer. I wanted to play Torchlight II before I saw this, and I want to play it even more now.
