A Veteran frontline Melee-Tank build, I call it the Soul Harvesting deck. Haven't tested on Nightmare yet but should yield favorable results.
Best used for Holly. Equip Stun Guns and Flashbangs for maximum effectiveness. Nearly no Doc-healing needed, but having a Doc in your squad is still recommended.
Disables: Aim Down Sights, Sprint.
Best Mobbing weapon: Machete
Recommended Bossing weapon: Hatchet
