What Do You Do With Sergei's Head In Firebase Z?

Black Ops Zombies has hit a turning point with the release of the Firebase Z map.

The map is massive compared to Die Maschine and there is a ton to check out within Firebase Z.

Players have been picking away at the amazing easter egg within the map.

Although there is the main easter egg, Treyarch has gone ahead and added some mini-ones.

One of these is revolved around Sergei's Head within Firebase Z.

Here's what to do with it.

 

Summary

In short, players will use Sergei's Head to ultimately open a safe within Colonel Kravchenko's room.

This can be done after collecting essence from zombies in order to charge Sergei.

Below is a quick rundown of this guide! 

 

Step 1: Find Segei's Head

While Sergei's head spawns in a random location each game, there is a way to narrow it down.

Sergei's head spawns around the outer edges of the Firebase Z facility - specifically in the defence areas.

Once done, head to the Field Hospital and place his head on the charging plate.

This is the table near the Data Center.

Step 2: Catch A Zombie

Next, weaken a Zombie and catch it using the Essence Trap.

The Essence Trap is obtained from the Memory Transference Station.

Make sure the Zombie is on very low health, otherwise it will not stay caught.

Once done, the Essence Trap will glow purple.

Head back to the table and place the Essence Trap in the small machine.

The head will reanimate briefly before exploding!

Step 3: Open The Safe!

Now that's done, you're basically finished!

Just head to the Colonel's Office and open the safe to claim your free perk!
