The WitchBorn: Enter Perdition

From BoardGameGeek:

Enter a Dark Fantasy where Perdition is overrun by demonic WitchBorn returned from the dead. WitchBorn tear their brothers and sisters apart with an insatiable blood lust. You number among a few roaming bands of survivors-maybe all that is left of your kind! Build your own war clan of eight survivors to recover lost cargo in WitchBorn infested plains. Enter Perdition is a story-driven miniatures skirmish. Use the supplied standup figures, your own miniatures, or expansion sets including Reaper Bones minis. The ever-changing stories are told by free web apps so no GM is needed. Play with one to six war clans and battle to take your world back. -description from the publisher
