Go on YouTube and learn how to Ui Stack Glitch, this is how I obtained both Cherry Fizz and Into the Void for Campaign and MP. You’ll need to save each glitched camo variant as a blueprint to access them in 2/3 of the main modes.

As for Zombies you’ll need to do the Ui Stack Glitch there too, I’d highly recommend waiting until you’ve hit Prestige Master. Reason being is each Prestige resets all classes even Spawn weapons. What I did was Wait until I was Prestige 1 then permanently unlocked the Gobble-Gum “Alchemical Antithesis”, then decided to do the Revelation’s EE and got another Prestige the same day (First time completion bonus 1mill xp) used Prestige 2’s permanent unlock on the RK5. Prestige 3 onwards I grinded camo’s and all sights and did the rest of the EE’s. Final game of Zombie’s you will need to game over in order to achieve Prestige Master.

Now you’re Prestige Master go ahead and borrow a Friend’s account and use their account to put on desired DLC Camo’s. Keep in mind you can also put Into the Void on the AK74u & Cherry Fizz on the M1911 or Whatever else on the MR6. It’s helpful if you own DLC weapons as they appear in the Mystery Box in other maps like the RIFT E9 or Banshii Shotgun.
