Chaaarge! cries the Empire. Waaagh! cries the Greenskins. Saaale! cry both in unison. From now through Monday, June 4, Steam hosts the Skulls for the Skull Throne sale—a roundup of discounted Games Workshop games, including Total War: Warhammer 2, Blood Bowl 2 and Vermintide 2. 

I reckon those three are the pick of the bunch—going for £29.99/$44.99 (-25%) £5.09/$6.79 (-66%) £17.84/$22.49 (-25%) respectively—but there's plenty more to sink your teeth into.
