Call of Duty: Black Ops Cold War’s Zombies mode introduced players to Firebase Z, a thrilling and lore-rich map filled with secrets, missions, and terrifying challenges. One of the most memorable and talked-about elements in Firebase Z is the mysterious Sergei’s Head. This item is more than just a grotesque Easter egg; it plays an important role in both gameplay and the narrative that connects the Dark Aether storyline. For players aiming to uncover every secret or complete all objectives in Firebase Z, finding and using Sergei’s Head is an essential and intriguing step.
Understanding Firebase Z and Its Complex Layers
The Map and Its Setting
Firebase Z is set in a Soviet outpost in Vietnam during the Cold War, blending military infrastructure with supernatural threats from the Dark Aether dimension. As part of the larger Zombies narrative, the map includes a main quest, side Easter eggs, and items crucial to progression. Among these, Sergei’s Head stands out for its mystery and usefulness.
Introduction to Sergei
Sergei was once a soldier or officer working within Omega Group operations. His fate was grim he was decapitated during experiments or as a result of some twisted punishment by the scientists. His head was kept in a containment jar and plays a part in Firebase Z’s lore and side quests. Collecting and delivering the head allows players to unlock additional rewards and engage with the story more deeply.
How to Find Sergei’s Head in Firebase Z
Step-by-Step Instructions
Finding Sergei’s Head can seem like a difficult task if you’re not sure where to look. Here’s how to find it:
- Activate Power First: Before Sergei’s Head can spawn, you must restore power to the facility by activating all Aether Reactors around the map.
- Wait for a Defense Round: After power is restored, you must survive a few rounds, especially a Defense round, which typically occurs near the Aether Reactor areas.
- Look Near Defense Sites: After the Defense round ends, head to the location where the battle occurred. You may find a glowing item on the ground near the end of the defense area. This is Sergei’s Head.
It’s important to note that the head does not appear in every game and may require multiple attempts before spawning, adding an element of randomness and replay value.
Visual and Audio Cues
Sergei’s Head is enclosed in a glass jar and emits a subtle blue glow. Sometimes it’s easier to locate by sound, as it gives off faint humming or bubbling noises that can help you track it down. If you’re playing with a headset, pay attention to ambient audio near Defense zones.
What To Do After Finding Sergei’s Head
Delivering the Head
Once you pick up Sergei’s Head, your goal is to bring it to the Field Hospital area of the map. Here’s what to do:
- Go to theField Hospitalin the Firebase section of the map.
- Locate a machine called theMemory Transference Station.
- Interact with the machine to insert Sergei’s Head.
When inserted, the device begins a short memory transfer sequence. You’ll hear audio logs and story dialogue that reveal more about what happened to Sergei and hint at broader Omega Group operations. It’s a vital moment for players interested in Zombies lore.
Be Ready for a Fight
Inserting Sergei’s Head into the Memory Transference Station often triggers enemy spawns. Expect a brief but intense wave of zombies or mimics trying to stop you. Prepare by placing traps, reloading weapons, and warning your team. The encounter is short but dangerous if you’re caught off guard.
Rewards for Completing the Sergei’s Head Objective
Loot and Bonuses
Completing this small Easter egg isn’t just for the story. Players are rewarded with valuable in-game loot including:
- High-tier salvage or weapon upgrades.
- Armor or Self-Revive Kits.
- Sometimes, a free Wonder Weapon (the RAI K-84) may spawn, depending on the round or difficulty level.
These rewards can give you a much-needed advantage in later rounds, especially when dealing with elite enemies like Manglers or Mimics.
Impact on Main Quest Progression
While Sergei’s Head is technically a side Easter egg, completing it can aid in progressing through the map’s main quest. The lore gained from the memory transfer provides context for future steps in the main storyline. Moreover, the gear obtained may make subsequent objectives easier, especially those involving boss battles or survival tasks.
Tips and Tricks for Easier Completion
Play With a Coordinated Team
While it’s possible to complete the Sergei’s Head sequence solo, it’s much easier with teammates. Assign one player to escort the head while others cover key routes. This makes the Defense rounds and follow-up zombie attacks easier to manage.
Use Stims and Armor Wisely
When holding Sergei’s Head, you may move slower or be less responsive during interactions. Having stims and full armor gives you a cushion in case you’re ambushed during the memory transfer phase.
Check Every Defense Site
If the head doesn’t spawn after your first Defense round, check other Defense sites as the item might have dropped elsewhere. Return to those sites after subsequent rounds just in case. The head’s appearance is often linked to RNG and progression.
