G4 has a two part preview of the upcoming new region/dungeon that is part of the Call to Arms expansion. I’m don’t know much about the lore of Warhammer, so I don’t exactly know how the egyptian undead monsters fit in, but The Land of the Dead sorta reminds me of the Mummy movies. I keep thinking Brendan Fraser is going to show up in one of these previews.
The Land of the Dead is set to be released sometime in June as part of the Call to Arms live expansion which has been releasing pieces since March. More information can be found on Mytics site.
