Call Of Duty: Black Ops Cold War - Using Meta Upgrades In Zombies


Call of Duty: Black Ops Cold War brought the heat with the Season 2 update not too long ago, making substantial changes to all three segments of the experience. Both multiplayer and Warzone got a wealth of new content, but arguably Zombies stole the spotlight - not only did Outbreak bring the Zombies experience to the open world, but with two new tiers of Meta Upgrades the strategic element gained a whole new depth.

Even with Black Ops Cold War having only received its biggest update yet, Activision is already planning for the next big thing in the Call of Duty franchise.

Here's what Meta Upgrades are, how to farm Refined and Flawless Aetherium Crystals, and how to elevate your gameplay to the next level with Tier 4 and 5 upgrades.

What are Meta Upgrades?

Meta Upgrades are the umbrella term that Treyarch uses to refer to the Tier IV and V upgrades in Call of Duty: Black Ops Cold War Zombies. At launch, Requiem operators had access to three tiers of upgrades spread out across perks, field upgrades, ammo mods and weapon classes, which increased their effectiveness and augmented their function.

With the introduction of the new tiers, your equipment and abilities will pack even more of a punch. In some cases Tier IV is just another numerical stat increase for an aspect of the weapon or ability in question that already benefits from a previous tier, but when it comes to Tier V, it's a real gamechanger in pretty much every instance.

How to get Refined and Flawless Aetherium Crystals

As powerful as the new upgrade tiers are, it makes sense that earning them should be a challenge. You will need to farm Refined Aetherium Crystals for Tier IV upgrades, and when gunning for the even stronger Tier V, Flawless - and thus even rarer - variants will also be needed.

The way to get these crystals isn't much different than the method of farming Raw Aetherium Crystals, except the stakes are higher this time. It is possible to earn the new crystal variants in both regular rounds of Zombies matches, and the new Outbreak mode - though the specific requirements are different.

In Zombies, crystals are awarded based on how far you get before dying or exfil. You need to reach at least Round 20 before you get Refined Aetherium Crystals, and Round 35 for the Flawless variant. In Outbreak, there is no round system - instead the rewards you earn are determined by the number of objectives you complete. It takes 3 objectives to get Refined and 4 to get Flawless Aetherium Crystals.

Since these thresholds are set pretty high up, it'll require a great deal of coordination and teamwork to earn them, and no small measure of skill.

Meta Upgrades - Tier IV and V

So what are we doing all this grinding for, anyway?

Just like regular upgrades, the Tier IV and V meta upgrades vary from category to category, so let's take a look at all the benefits you'll incur from investing in these new improvements.

Perks

Ammo Mods

Napalm Burst Ammo Mod progression

Field Upgrades weren't the only category to welcome a new arrival in Season 2 - Shatter Blast is a powerful new ammo mod that debuted at the same time, bringing explosive ammo to a whole new level.

  • Shatter Blast
    • Tier IV: 100% explosion range increase
    • Tier V: chance to trigger explosive barrage, removing enemy armor and knocking them back
  • Brain Rot
    • Tier IV: affects special enemies
    • Tier V: affects 3 enemies
  • Cryofreeze
    • Tier IV: affects special enemies

    • Tier IV: affects special enemies
    • Tier V: stun effect can spread
  • Napalm Burst
    • Tier IV: affects special enemies
    • Tier V: burn effect can spread to 5 enemies

Weapon Classes

Special Weapon Class progression

Weapon class upgrades infer permanent boosts to certain stats for all weapons in a given class, regardless of how you acquire them when in a game of Zombies. The new upgrade tiers work a little differently with Weapon Classes than the other categories, in so far as every class except Melee gets the exact same Meta Upgrades.

At Tier IV, they all get the same bonus as at Tier I but amplified, and at Tier V they get an amplified version of the upgrade at Tier II. The odd one out here is Melee, where the Tier IV upgrade is an increased mirror of Tier II, and Tier V gives you a chance to get healed on each hit. This just might be the most significant upgrade of them all to be introduced in Season 2.
