After the Witch Hunter (opens in new tab) and the Waywatcher (opens in new tab) comes the class I will probably play as, if I ever embark upon Fatshark's Warhammer: End Times - Vermintide (opens in new tab). It's the Empire Soldier, and I will be required to play as him because a) he has some lovely mutton chops, and b) he wields a blunderbuss. Markus Kruber is detailed here (opens in new tab), with an unnecessarily long backstory, a few images, and details of his weapon set (he wields big, heavy things like greatswords, warhammers, and blunderbi).
Also, here's a video from PCGamesN.
See the way he turns Skaven into mush with his giant hammer? That's why you'll be playing as the Empire Soldier too.
Warhammer: End Times - Vermintide is out October 23 (opens in new tab).
