Black Ops 3 Der Eisendrache Easter Egg Guide
The Der Eisendrache map in Call of Duty: Black Ops 3 remains a fan-favorite experience for Zombies enthusiasts due to its atmospheric setting and complex narrative integration. Completing the main Easter egg quest, known as My Brother's Keeper, requires tactical coordination, precise map knowledge, and properly upgraded weaponry. This comprehensive guide outlines the essential phases players must navigate to successfully conquer the ancient Austrian fortress and complete the storyline milestone.
Prerequisites and Wonder Weapon Upgrades
Before attempting the primary narrative steps, players must activate the power supply and awaken the slumbering dragons located around the castle grounds. Feeding these beasts unlocks the standard Wrath of the Ancients bow, which serves as the foundation for the entire quest line. Depending on your lobby setup, you will need to upgrade these base weapons into specialized elemental variants to trigger the subsequent phases.
In a ranked or solo match, the number of required upgraded bows scales exactly to the total number of players participating in the game. Team members should coordinate early to assign specific paths, ensuring that the Storm, Void, Fire, or Wolf variants are fully prepared before round ten. Having these powerful weapons ready will drastically reduce the difficulty of surviving during the trickier lockdown sequences.
Time Travel Sequences and Keeper Relic Replication
Once your elemental arsenal is established, the next major objective involves interacting with the underlying temporal mechanics of the Griffin Castle research station. Players must utilize the upgraded bows to initiate a specialized wisp hunt, which spawns glowing electrical anomalies across various rooms during specific round intervals. Successfully tracking these wisps allows the team to travel backward through time to witness crucial historical events.
During these brief chronological shifts, you must look closely at the environment to memorize safe combinations and locate hidden ancient artifacts. Retrieving the Golden Rod from the past enables the team to repair the central tomb mechanism located in the lower courtyard. Bringing this device online triggers the arrival of the Keeper spirit, which guides players through the final steps before the climactic encounter.
The Keeper Soul Collection and Boss Arena Preparation
The Keeper spirit requires significant elemental energy to fully materialize its physical form and open the gateway to the final arena. Players must follow the floating entity as it moves between four distinct stone tablets situated around the facility grounds. Standing within the glowing circular zone, players must eliminate approaching zombies using the specific bow type matching the color of the screen border.
Completing this spiritual charge sequence grants access to the focal containment chamber beneath the rocket pad area. Before interacting with the final terminal, the entire team must stock up on ammunition, heavy armor, and strategic GobbleGums like Near Death Experience or Shopping Free. Ensuring that your tactical equipment is fully optimized prevents sudden team wipes during the intense final stages.
Conquering the Corrupted Keeper Final Encounter
The ultimate battle takes place inside a circular chamber where players must defeat the massive Corrupted Keeper entity while surviving endless waves of skeleton variants. The core strategy revolves around dodging the boss's devastating shockwave attack by taking cover behind the pillars located on the edges of the room. Players must wait for the central core to expose its glowing chest before unleashing sustained firepower.
Utilizing the Ragnarok DG-4 gravity spikes is essential to pinning down the boss and interrupting its lethal casting animations during the second phase. Once the creature sustains enough damage across three distinct rounds of engagement, the arena will collapse, returning players to the main map for the final cinematic conclusion. Successfully finishing this sequence rewards the lobby with permanent perks and unlocks the map achievement.
