How to build the Ray Rifle in Firebase Z

In order to build the R.A.I. K-84, you’ll need to go through a few steps and collect the correct components. We haven’t been able to 100% complete the Ray Rifle because at time of writing, the Firebase Z easter egg is not yet active (it’ll be good to go at 9am PST/12pm EST/5pm GMT), but here are all the steps to build the Ray Rifle in Firebase Z: Sound like a pain to get? Well, in all honesty, it is. But hey, if you’re feeling lazy you can always try your luck in other ways!

Use the Mystery Box

You can try to get lucky with Mystery Box rolls if you want the Discordian Disruptor but don’t want to actually work for it. In order to do this, just find the Mystery Box - it’s clearly visible with a giant column of blue light shooting off into the sky - and pay 950 points to roll for a gun. If you’re lucky, you might get a Wonder Weapon! If you or a teammate picks up a Fire Sale, all the Mystery Boxes will spawn in all their potential positions throughout the map as well. It’s well worth rolling whenever that happens, especially considering the Fire Sale discounts Mystery Boxes to be just 10 points.

Legendary Trial rewards

In the helipad area of the Firebase (just next to the teleporter), you can undergo trials in exchange for points. These may seem ridiculous, such as ‘stay in a certain area for a long time’ or ‘get headshot kills on zombies’, but their rewards can be fantastic. You can even stack reward rarity too. Once you do a trial, your reward tier will be displayed on the left side of your screen. Keep doing trials until this says ‘Legendary’, and claim it from a podium next to the place you start the trials. There’s a chance this reward will be the Ray Rifle. You can even make it more likely to occur by owning all Perk-A-Colas, because they’re also in the pool for Legendary trial rewards. Take them off the table and try your luck! That’s all for our Zombies guide on how to build the Ray Rifle in Firebase Z! It’s a bit of a hassle, but worth the effort if you want that super-powerful Wonder Weapon. If you’re not feeling Zombies mode, we have plenty of other COD guides for you though - check out our page on the best loadouts in Warzone, as well as all the War Tracks you can play in your Warzone vehicle.
