Total War: Warhammer's Call of the Beastmen screenshot

Creative Assembly has been teasing the Beastmen as a playable race for a couple of days now, but unfortunately for them their playerbase is a bit overzealous when it comes down to hunting even the tiniest of clues. 

In other words, someone has already managed to not only unearth the hidden cinematic trailer, but also a bit of information on the DLC itself. First things first, here's the trailer showcasing the half-human aberrations in battle against some poor Empire soldiers:

 

Call of the Beastmen is going to be Total War: Warhammer's first Campaign Pack. It'll bring with it the Beastmen as a new playable race in both the campaign mode and multiplayer, but also a brand new Story Campaign reserved for the them alone, currently titled as "An Eye for an Eye".

As far as their gameplay features are concerned, the Beastmen will be able to use an array of new mechanics, including the ability to travel through overgrown patches of forest in order to outmaneuver and ambush anyone foolish enough to follow them. Specifics are currently in short supply, especially since Call of the Beastmen hasn't been officially announced just yet, but given their lore I'm fairly confident in saying that the Beastmen will be a highly aggressive, melee-orientated race of nomads, constantly sweeping through the campaign map in an orgy of death and destruction, all in the honor of the Chaos gods.

While Call of the Beastmen will be a paid piece of DLC, there will be a free update accompanying it as well. This free DLC will introduce Lore of the Beasts, a brand new Lore of Magic that focuses on enhancing allies and summoning gigantic beasts from the earth itself. There's also going to be a corresponding Hero unit added to the Empire faction as well, though I'm not sure if this new Lore will be exclusive to them or not.

Call of the Beastmen and the free update that comes along with it will be arriving to Total War: Warhammer on July 28. If you're interested in any more information, I'm afraid you'll have to wait for the official Steam page to finally become active as currently its just redirecting to the storefront.
