How to Get Wonder Weapon in Firebase Z – Cold War Zombies

Firebase Z’s most powerful Wonder Weapon is up for grabs already, here’s how to get it.

If you’re looking to get your hands on the Firebase Z Wonder Weapon (A.K.A the R.A.I. K-84), look no further. This powerful gun will really help you out at later rounds and is a great endgame weapon.

As a cross between the Ray Gun and the AK-47, the R.A.I K-84 has two ways of firing. Its primary fire is a rapid energy blast, but you can toggle the fire mode at will.

With its secondary fire, the Wonder Weapon fires a purple grenade. Enemies that step into its radius are both slowed and damaged.

What’s more, shooting this grenade will detonate it, dealing heavy damage to enemies in its radius.

Firebase Z: How to Get the Wonder Weapon

It appears that there are actually 3 ways of getting the Firebase Z Wonder Weapon in Cold War Zombies right now.

Here’s a guide for every way we currently know that the Wonder Weapon can be acquired.

Mystery Box

As we saw in the Firebase Z reveal trailer, the Wonder Weapon is hiding in the new Mystery Box. Rolling for a new weapon could net you the gun fairly quickly.

However, you’ve got to be lucky for this method. It’s worth noting though, that using the Mystery Box on higher rounds usually leads to increased chances of obtaining the Ray Gun.

We imagine that the Wonder Weapon’s odds get a similar boost.

This method is also down to chance, but the Wonder Weapon can spawn as a Trial Reward. Like in Die Maschine, players are able to activate Trial Computers and accomplish a challenge to earn rewards.

One such computer can be found in the Helipad area, where players arrive after teleporting to Firebase Z. Activate the trial and complete it to the best of your ability.

Once done, you’ll have a reward available, based on your performance. For the Firebase Z Wonder Weapon, you’ll need a Legendary reward.

This may take a little grind, but keep doing Trials without claiming your reward to upgrade its rarity. Then enjoy your Legendary reward, and hope it’s the R.A.I. K-84.
