Modern Warfare 3 cryogenic ammunition: How to get this mod in Call of Duty Zombie mode?

 You've arrived at the Freeze mission in the main story of Call of Duty: Modern Warfare 3's Zombie mode, but you can't get your hands on the cryogenic ammo to complete the challenge that requires you to eliminate zombies with this mod? In this MW3 article, we give you all our tips for getting it quickly.

How to get the Cryonic Ammo Mod in MW3?

To get your hands on this mod in Call of Duty: Modern Warfare 3 (2023) Zombie, there are different methods. The first is to complete contracts in Urzikstan to obtain a Cryonic Ammunition Mod Creation Blueprint. The drop rate is relatively low, so you will have very little chance of running into him, especially since there are many schematics to collect in Zombie mode. However, if you received it, and then extracted it with the helicopter, do not hesitate to look through your acquisitions to make it. You will be able to recreate a mod every three hours.

Otherwise, if you don't have a diagram at hand, you'll have to roll up your sleeves. The second most reliable method of obtaining ammo mods is to complete world events that are zombie-related, including the Aether Nest or Infected Fortresses. In these places, you can find a good quantity of Aether Caches. These chests contain almost exclusively resources related to zombies, so mods, ether crystals, monkey bombs, cans of assets, etc.

On the other hand, Aether Caches can be found almost everywhere on the map. Although Aether Nests and Infected Fortresses guarantee the availability of these chests, it is still possible to find them randomly in the different buildings of Urzikstan.

Note that events linked to zombies, so target contracts or robbing the weapons cache (to name just two), are also favorable for dropping mods, so the one that cryogenics. You can find them in the Reward Rift, once your mission is completed.

How to unlock Aether Chests in Aether Nests and Fortresses in Zombie mode?

Upon arriving in the “Aether Nest” and “Aether Fortress” world events, the Aether caches will be locked. To make them accessible, your mission will be to destroy the yellow cysts that are placed everywhere in the infested building.

• Search everywhere, even in the toilets, on the ceiling, behind doors... These pustules are hiding everywhere!

With each cyst destroyed, a small wave of zombies appears. So prepare your gas masks (obtainable from mercenaries and from time to time from armored zombies in the level 2 zone), your armor plates and your ammunition, because you are going to have to do a big clean-up!

When the last cyst is removed, your operator will be able to remove his gas mask and all the Aether caches will be within his reach . All that's left to do is cross your fingers for quality loot.
