Zombies’ crucial Field Upgrades have been bolstered in Black Ops Cold War Season 2, giving players new abilities that can drastically shift the flow of those undead battles. Field Upgrades have received two new tiers each. But that’s not all. Joining the other pre-existing Field Upgrades is Frenzied Guard, an aggro- and armor-generating power-up.
The new tiers aren’t acquired with simple Raw Aetherium Crystals like the first three tiers. Only Refined and Flawless Aetherium Crystals have the power to unlock the potent buffs. Fortunately, we have detailed how to secure the latest in-game resource so that cost is not an issue.
Now let’s take a look at how your go-to Field Upgrades have evolved in their added tiers.
All Tier IV and V Field Upgrades
Frenzied Guard (New)
Tier IV: Increase duration [of enemy aggro] to 15 seconds.
Tier V: Normal enemies are slowed to walk speed while active.
Frost Blast
Tier IV: Increase maximum charges to 3.
Tier V: Normal enemies are frozen for 5 seconds and insta-killed when damaged.
