How to Unlock Civil Protector in CoD BO7 Zombies? | The Brutal Round 60 Challenge

Category: CoD: Black Ops 7 Posted: Feb 14, 2026 Views: 728

Of all the relics in Astra Malorum, the most troublesome and perhaps the least useful is Civil Protector Relic. Due to its high difficulty, many players are reluctant to unlock it.

Even players who are constantly chased by O.S.C.A.R. or struggle with Ol' Tessie's lighting are still willing to challenge themselves. Therefore, let's see how you should reach round 60 and unlock this relic.

How to Unlock Civil Protector in CoD BO7 Zombies? | The Brutal Round 60 Challenge

Preparation Phase

The primary condition for unlocking Civil Protector Head is being at Tier 2 (cursed) difficulty. Under this condition, the choice of Relic will directly affect your survival and efficiency.

Note that you should avoid using Gong Relic, as it disables field upgrades. Field upgrades are essential for both dealing with O.S.C.A.R. and activating Ol' Tessie.

It's recommended to carry relics that enhance survivability and mobility. You can carry the following Relics:

  • Teddy Bear
  • Spider Fang
  • Focusing Stone
  • Matryoshka Doll

To survive until round 60, you need to focus on the energy mine. You can pair it with the following Field Upgrades:

  • Smart Mine: It waits for multiple enemies to enter its blast radius before exploding.
  • Recycle: Recycles the energy mine after killing an enemy to recharge it.
  • Extra Charge: Increases the recharge speed.

The significance of this combination is that you need to trigger Ol' Tessie's mechanics with Energy Mine, but you can't let the mine kill the last zombie, thus ending the round. Smart Mine's precise target acquisition avoids this problem.

 

To deal with the zombie hordes and Oscar's pursuit in the high round, you also need to temporarily switch to Aether Shroud and equip it with Extra Charge and extension mods to ensure enough stealth time to escape enemies in critical moments.

How to Reach Round 60?

Unlocking Civil Protector Relic begins with surviving to round 60. From round 50 onwards, O.S.C.A.R. will relentlessly pursue you at extremely high speed.

Low Round Tips

In Low Rounds, O.S.C.A.R. isn't a significant threat. Astra Malorum has relatively spacious indoor halls. Simply run in a large circle, maintaining a consistent rhythm; O.S.C.A.R. will have difficulty hitting you.

The only thing to watch out for is his UFO attack. When his UFO begins charging and emits a special sound effect, immediately dodge sideways. Mastering this rhythm allows you to completely ignore O.S.C.A.R. and focus on clearing out other enemies.

How to Kill O.S.C.A.R.?

How to Kill O.S.C.A.R.?

While you can ignore it, in High Rounds, a high-speed elite enemy constantly following you is always a threat. Here are two reliable strategies for killing O.S.C.A.R.:

Traps

You can lure O.S.C.A.R. to a trap in the central outdoor area. The trap will quickly break his shield and deal considerable damage to him and surrounding zombies. The downside is that it creates a chaotic scene, and one trap isn't enough to kill a full-health O.S.C.A.R.

Kill Streak Bonuses

Both Death Machine and War Machine can deal massive damage to him. Death Machine is arguably better, as its projectiles are more consistent and its firing rhythm is easier to control. Note that if you save and quit the game midway, your kill streak bonus will be lost, so it's best not to interrupt it.

If you want an easier approach, you can use LT53 Kazimir. After throwing LT53 Kazimir to attract zombies, use Death Machine or War Machine to unleash fire on O.S.C.A.R. Kazimir's ability to gather zombies creates a clean firing window, making it the optimal solution for casual players.

One trick is that if you kill O.S.C.A.R. in round 59, it won't spawn in round 60. This means you can focus entirely on Ol' Tessie puzzle.

Ol' Tessie Puzzle

Ol' Tessie Puzzle

You can only begin Ol' Tessie puzzle after successfully reaching round 60.

Activating Light Order

Previously, players had to guess the activation order of the indoor chandeliers by brute force, but now the mechanism is clear: the flashing order of Ol' Tessie's lights is the correct activation order, and this order resets every round.

You simply need to place an energy mine in front of the abandoned Ol' Tessie. After it explodes, its four lights will start flashing. The flashing order is the order in which you need to use PHD Flopper to pass through the corresponding chandeliers.

If you are standing directly in front of Ol' Tessie, this order corresponds exactly to the positions of the four chandeliers in the room. Your task is to run to the corresponding chandelier in order and perform PHD Flopper without killing the last zombie.

Tips

Do not end the round prematurely, because the chandelier order only applies to the current round. Once you enter the next round, Ol' Tessie will randomly re-flash.

It is recommended to bring Brain Rot ammo module. Its infection effect will not accidentally kill the last zombie, giving you ample observation time. Items like LT53 Kazimir, which may kill all zombies, should be used cautiously when only one zombie remains.

Cursed Trial

When the four chandeliers go out in sequence, the system will indicate successful unlocking and a portal will appear behind the mystery box.

Entering the portal will lead you to the final cursed trial of Astra Malorum. All zombies in this mode move very quickly, so be sure to replenish your armor, ammo, and killstreak bonuses beforehand.

During the trial, HVTs will spawn in sequence: Mimic, Uber Klaus, and O.S.C.A.R.

Uber Klaus has extremely high health but moves slowly. Use Aether Shroud and Combat Axe to safely deal with them. O.S.C.A.R will reappear with enhanced tracking abilities; continue using Death Machine and War Machine to kill them.

Upon successfully completing the trial, you will officially obtain Civil Protector Head. It is not a good Relic, and you will lose one perk for every 100 zombies killed, which is mostly a negative effect, but it's still worth collecting.


In any case, this is a rather challenging task. If your level is a bit low and you haven't unlocked other relics, you can buy cheap and reliable CoD Black Ops 7 Bot Lobbies in IGGM. This will allow you to quickly level up in Zombie Mode and unlock some simple Easter eggs.
