The Beast Walker

From publisher blurb: Through forest and over hill you've tracked this monster - elusive and powerful, spoken about in legends and myth. You're face to face with the monster, your weapon by your side. You take a deep breath and feel your soul throb as you unleash the spirit of a beast. You stand beside your ally, ready to fight. The Beast Walker is a complete, video game inspired, playbook for Dungeon World. Capture a beast's soul within your own and unleash them to brutal effect in combat!
