The Creative Assembly is working on a new Total War game set in Games Workshop's Warhammer universe.

The studio accidentally revealed the game by referring to it in a new art book that covers the breadth of its portfolio.

The art book was supposed to start shipping at the end of this month, but one fan got their hands on it early.

Today's new is not entirely unexpected. Sega secured a license to make games set in the Warhammer universe in 2012.
