Der Eisendrache remains one of the most celebrated Call of Duty: Black Ops 3 Zombies maps due to its atmospheric design and deep gameplay mechanics. Set in a snowy medieval castle in Austria, the map introduces iconic wonder weapons, movement options, and lore-heavy questlines. Understanding its core layouts and secrets is essential for players looking to master high rounds or complete the main story quest.
Navigating Castle Griffin and Unique Map Features
Castle Griffin is built across multiple vertical levels, forcing players to adapt to tight corridors, open courtyards, and subterranean passages. To move efficiently, players can activate the Wunderfizz machine, power up landing pads, and use the central tram system for early-game items. Mastering these transit options makes traversing the snowy fortress significantly easier during tense survival situations.
The map also features zero-gravity mechanics inside the undercroft area near the pyramid. Players can trigger this low-gravity state by standing on wall pressure plates until they glow blue. This unique environmental feature allows players to wall-run, dodge aggressive zombie hordes, and access essential upgrade quest steps.
Crafting and Upgrading the Wrath of the Ancients
The centerpiece of Der Eisendrache is the Wrath of the Ancients bow, a formidable wonder weapon obtained by feeding three dragon heads mounted around the castle. Each dragon requires a set number of zombie sacrifices before crumbling away. Once all three dragons are satisfied, players can claim the base bow inside the tomb room.
Players can further upgrade the bow into four elemental variants: Lightning, Fire, Void, and Wolf. Each bow requires completing a specific set of quest steps scattered across the map, offering distinct area-of-effect damage abilities. These upgraded weapons are critical for dealing with high-round zombie waves and surviving boss fights.
Uncovering the Main Easter Egg Quest
The primary Easter Egg quest on Der Eisendrache, known as My Brother's Keeper, takes players through a cinematic narrative involving Dempsey 1.0. Completing this quest requires acquiring at least one upgraded bow, building the Ragnarok DG-4 wonder weapon, and traveling back in time using a teleporter. Players must carefully execute each step to avoid getting overwhelmed by continuous zombie spawns.
The quest culminates in an intense boss encounter inside the undercroft against the Keeper boss. Surviving this multi-stage encounter requires strong communication, proper perk selection, and strategic use of the Ragnarok DG-4 to trap the boss. Defeating the Keeper rewards players with a memorable cinematic cutscene and permanent perks for the remainder of the match.
Hidden Secrets and Tactical Equipment
Beyond the main story quest, Der Eisendrache is packed with smaller secrets and buildable gear. Players can collect three hidden components across the castle to assemble the Rocket Shield, which provides vital back protection and a thruster attack. Additionally, free perk power-ups and music Easter eggs can be unlocked by interacting with radio towers and hidden teddy bears.
Another valuable secret is the free GobbleGum Easter egg, which rewards careful players with extra consumables. By leveraging buildable items, elemental bows, and side quests, players can establish a powerful setup early in the match. Der Eisendrache continues to stand as a gold standard for cooperative Zombies experiences.
