This article will guide you on How To Slow 50 Zombies & 10 Hellhounds Cryo Call Of Duty MWZ
To start, the player first needs to find Cryo Ammo in Aether chests, which can be discovered in both strongholds and regular Aether areas. Once you’ve obtained the Cryo Ammo, equip it with a weapon in the tier 2 zone.
Remember, simply defeating enemies with the Cryo Ammo won’t count; you must use it to slow them down. Apply the Cryo Ammo to your primary weapon and head to the tier 2 zone. Search for missions with objectives that spawn many enemies to complete this challenge.
