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.
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.
