Usually, Slaughterborn would be the name of something like an expansion for a game. But, in this case, it's the name of one of the minis in Warcry's upcoming Red Harvest set. Get a look at him in this preview.
From the article:
Surviving the Eightpoints is no walk in the park, and many Warcry warbands turn to strange mutations or arcane rituals to make it through another bout of vicious skirmish combat. Some exceptional individuals, however, have no need for these puny tricks to emerge triumphant from the Red Harvest – requiring only grit, a good pair of boots, and a hecking big sword.
As if he couldn’t seem any more intimidating, he’s called a Slaughterborn.
Rather than decking themselves out in gaudy spider masks and fancy cloaks, the Slaughterborn knows that a solid weapon and the favour of the Ruinous Powers are all a person needs to win their place at the Everchosen’s side.
