Where to find the RAI K-84 in Firebase Z

In order to be able to survive as long as you can in Firebase Z, you’re going to need some pretty potent weaponry. There’s the usual array of Black Ops Cold War default weapons and the almighty Ray Gun that everyone so desperately wants.

But the gameplay trailer for Firebase Z revealed an interesting new weapon called the RAI K-84. Getting a hold of it is a lot more simple than you might think too.

In order to get your hands on the RAI K-84, players will need to do one of the following:

  • Obtain it from the Mystery Box
  • Build it using its blueprint

Getting the RAI K-84 from the Mystery Box

If you’re unaware, the Mystery Box costs $950 to use. Once you’ve paid the fee, then it will begin an RNG process of running through the game’s whole collection of weapons. After several seconds, you will be presented with whichever weapon the game has randomly decided for you.

It could be a weak pistol, the elusive Ray Gun, or it could indeed be the new RAI K-84. If you’re struggling to find the Mystery Box, then keep a lookout on your minimap for its symbol, or memorize its locations that are usually designated with a recurring symbol or object.

Building the RAI K-84 using its Blueprint

If you’re not content with leaving your procurement up to chance, then manually creating the RAI K-84 could be the better option.

In order to do so, follow these simple steps:

  1. Ensure sure three power generators are all turned on
  2. Go to the Weapons Lab
  3. Pick up the Blueprint from the wall
  4. Make your way to the Scorched Defense area and find the incinerated body next to the tank
  5. Trigger the command to pull its eye out
  6. Head back to the Weapons Lab and plus the eye into the computer’s Retina Scanner
  7. Take the key from the now unlocked drawer next to the computer
  8. Now go to the Barracks area and unlock all the lockers using the key
  9. An artifact will be revealed and several Mimics will spawn
  10. Kill the Mimics and pick up the Barrel
  11. Keep killing Mangle’s until one of them drops the Magazine
  12. Place it on the table in the Weapons Lab with the big bomb on it, wait a few seconds, it should charge, and then you can pick it up again
  13. Go to the computer, activate it, and it will begin a sequence telling you which parts of the Village Mess Hall’s dartboard you’ll need to shoot
  14. Shoot the three in order, then shoot the bull’s eye, and then pick up the Converter
  15. Finally, head back to the Weapons Lab table and assemble the RAI K-84

You’ll have to decide how much you want to try out the new gun as at the end of the day, the Mystery Box is a calculated gamble. Wh A few attempts here and there will rack up a huge bill that will waste away money that could’ve been better spent on a life-saving perk such as the new Tombstone Zombies Perk.

Whereas the building method requires a lot of time and moving around. Rounds will be piling up and you’ll still need to Pack-A-Punch the gun as well.

So make sure you weigh up your options first!

Best KSP 45 loadout for CoD: Cold War Season 5

Buffs have made the KSP 45 a fearsome Cold War SMG, so here’s the best loadout with perks and attachments to complement it.



Best Cold War KSP 45 Loadout Class

The KSP 45 has become of CoD: Black Ops Cold War’s best weapons. Treyarch did buff it, and this SMG has been a must-use gun since then. Here is the best Cold War KSP 45 loadout in Season 5, including attachments and Perks.

At the beginning of Cold War, the likes of the MP5, Krig 6, and the FFAR were tearing up lobbies, so guns like the KSP 45 never had a chance.

A burst-fire SMG is a weird hybrid to begin with, but weak stats didn’t help it. But now, it has increased viability as a lobby-owning laser beam.

To ensure that players get the most out of it, we’ve gone through and kitted it out with the best attachments and Perks to discover its best self in Black Ops Cold War Season 5.

Best Cold War KSP 45 loadout

Best Cold War KSP 45 loadout class attachments

To ensure you get the most of Cold War’s KSP 45, ensure you have the Gunfighter wildcard equipped to increase your maximum attachments.

  • Optic: Visiontech 2x
  • Muzzle: Muzzle Brake .45 APC
  • Barrel: 10.2″ Rifled
  • Body: Steady Aim Laser
  • Underbarrel: Field Agent Foregrip
  • Magazine: 45 Rnd Drum
  • Handle: Serpent Wrap
  • Stock: Wire Stock

The improved effectiveness of the best Cold War KSP 45 loadout means we want to use this at different distances, so the Visiontech 2x will cover that. The gun’s accuracy is now a big factor in its efficiency, so instead of favoring one or the other, we’ve applied the Muzzle Brake .45 APC to give its vertical recoil a tiny boost.

The 10.2″ Rifled barrel makes the best Cold War KSP 45 loadout even more deadly at range, and the Steady Aim Laser makes it equally deadly at close range. The trusty Field Agent Foregrip bolsters vertical and horizontal recoil whilst the Fast Mag offers super-quick mag changing.

We’re going to give the KSP much faster ADS time thanks to the Serpent Wrap, and the Wire Stock lets us more around more freely with less penalty to sprinting.

Best Perks to use with Cold War KSP 45 class

  • Perk 1: Flak Jacket
  • Perk 2: Assassin
  • Perk 3: Ghost

Staying alive is the name of the game with the KSP 45, as its power can help you to achieve some insane scores. So Flak Jacket provides immunity to the litany of explosive devices that Cold War has in store for players.

Assassin supports this idea by rewarding you with more points for killing enemies on a Scorestreak, and Ghost makes you invisible to tracking devices.

Most recent AK-47 buffs & nerfs in Cold War

Treyarch has tinkered with the KSP 45 in Cold War Season 5, just giving it a couple of minors adjustments for players to consider.

Here are the most recent changes to the KSP 45:

  • Reduced Effective Damage Range from 25.4m to 22.86m
  • Slowed burst fire delay from 0.066 to 0.083

How to unlock the KSP 45

The KSP 45’s newfound power can only be utilized once you reach Level 37.

Doing so allows you to create the best Cold War KSP 45 loadout class, and you can also access it in Warzone Season 5 as well.

Best alternatives

The Milano 821 is another weapon that has become more popular in Black Ops Cold War, making it a fun alternative, especially after it also received recent buffs.

If you need something a bit meatier, then the Krig 6 or Stoner 63 could do wonders as well.

Warzone & Cold War Season 6 cinematic teases Mason’s return

Warzone and Black Ops Cold War have a new Season 5 outro cinematic hinting at Mason’s importance in the story for Season 6 of the Call of Duty games.



Woods and Hudson talking

The latest cinematic for Black Ops Cold War and Warzone Season 5 has been released, and players are excited about the reference towards Mason returning.

Black Ops Cold War and Warzone have had a successful season so far, keeping players entertained with the ongoing story, new weapons, and new modes like the Iron Trials for Warzone Season 5 Reloaded.

As we enter the final season for Black Ops Cold War before Vanguard‘s release, which will inevitably integrate with Warzone, players have been given a hint towards Mason’s return in a brand new cinematic.

Woods and Mason meeting in an alleyway to discuss Adler going Rogue

Treyarch released a new Season 5 outro cinematic on their YouTube channel on September 23, carrying on the ongoing story that has spanned the last five seasons.

For those still keeping up to date with the details, this outro cinematic plays a pivotal role in setting up the final season for Black Ops Cold War.

Black Ops Cold War will enter its final season soon, and players are desperate to find out who the last operator will be. It seems the last operator could be a fan-favorite character from the Black Ops series, Mason.

Although the cinematic is only a minute long, players can gain some critical information from it. Hudson and Woods are having a conversation about Adler’s disappearance, discussing what they should do next.

Ultimately, they decide that Woods should go after Adler, who is in Verdansk, while also mentioning the return of Mason, whose experience with the numbers could give them the edge.

You can find the official description of the new Warzone and Black Ops Cold War cinematic below:

“The news is flooding in: more Operators have abandoned their missions. Mounting evidence suggests that Adler has gone rogue. Disturbed, Hudson sends Woods to find Adler and bring him in… along with the one person whose Numbers Program intel could provide the edge they need.

The showdown begins in Season Six.”

We’ll have to wait for Season 6 to see where the story will go, but it’s set up to be an exciting end to what’s been a great seasonal story.

New Cold War Sai weapon exploit lets Zombies players skip doors

Black Ops Cold War players have discovered an exploit with the Sai melee weapon that lets them skip doors in Zombies mode.

A new exploit has been discovered with Black Ops Cold War’s new Sai melee weapon which lets players skip through the first door in the Firebase Z map in Zombies.

Black Ops Cold War Zombies received some new content in the Season 5 Reloaded update, including a new Black Chest World Event in Outbreak, a Rampage Inducer for round-based maps, and a brand-new weapon.

A new melee weapon called the Sai became available for players as part of The Numbers event. Now, players have discovered that this weapon actually lets them skip through doors in Zombies mode.

Sai in Black Ops Cold war

Various players reported being able to go through the first door at Firebase Z while they had the Sai equipped. This led to a response from lead developer Mark Maestas, who was well aware of the situation.

Surprisingly, the developer talked about this exploit with enthusiasm. “Dear Zombies players, yes you can skip the first door in Firebase Z,” tweeted Maestas. “Zombies can come and greet you too. GLHF!”

While these kinds of things are often addressed in update patches, Mark’s response makes it seem like the developers aren’t currently planning on doing anything to fix this exploit.

With this exploit, players will be able to access greater levels of Zombies much quicker than before, and the undead will be able to come to them as well.

It’s possible that the developers are going to avoid fixing this one exploit so that they can focus on fixing the Zombies’ pathfinding instead, ensuring that the exploit doesn’t ruin the game.
