The Black Recluse, Forge Warden

The Black Recluse, Forge Warden is a Fallen Walker of the Kell's Scourge syndicate and the final boss of the Bergusia Forge in the European Dead Zone. It was deployed to defend the forge from Guardians during the Season of the Forge. Igniting the forge takes three waves: kill the glowing blue enemies for batteries and throw them into the forge to extend its timer. The Recluse appears in the final wave, and its leg armor must be shot off to expose the core, which can be damaged while the walker is down. Much of the difficulty comes from the Fallen that assist it.
