Discover how to unlock the Chrome-Atose Blueprint in Black Ops 6 and Warzone for free in this quick and simple guide.

The Chrome-Atose Blueprint in Black Ops 6 and Warzone is a reward in the new Operation Hell Ride event. Players can unlock it for free as long as they fulfill the necessary criteria. Unlike some of the recent in-game events, Operation Hell Ride asks players to complete certain challenges. Upon completion, they are awarded with in-game items. One such item happens to be the Chrome-Atose Blueprint for the GPR 91 Assault Rifle. It covers the entire firearm with a skin of chrome, giving it a shiny and premium look.
Needless to say, it also comes with a few attachments that improve the weapon. So, without any further ado, let us take a quick look at how you can unlock the new Chrome-Atose Blueprint for free.
Guide to Unlocking the Chrome-Atose Blueprint in Black Ops 6 and Warzone
To unlock the Chrome-Atose Blueprint in Black Ops 6 and Warzone, you must complete any one of these Operation Hell Ride event challenges:
- Multiplayer: In Ransack, earn 15000 total Score
- Zombies: Spend 30000 total Essence
- Warzone: Purchase 3 UAVs at Buy Stations

Upon completion of any one of these challenges in your preferred game mode, the Blueprint will be unlocked. Furthermore, if you own the Season 5 BlackCell Battle Pass, you’ll unlock a premium BlackCell variant of this Blueprint as well. If you’re wondering about how this Blueprint enhances the GPR 91, it features the following attachments:
- Optic: Willis 3X
- Barrel: Reinforced Barrel
- Muzzle: Compensator
- Magazine: Extended Mag I
This leaves one more attachment slot free (without the Gunfighter Wildcard) for you to customize its performance in-game. Needless to say, all attachments for this Blueprint are wrapped in Chrome.
That said, there are a few things that you must consider. First, the Chrome-Atose Blueprint is the fifth reward in the Operation Hell Ride event, and hence, you must first unlock all four previous rewards. Only doing so will make you eligible to unlock this Blueprint. Second, this is a limited-time event and is set to end on October 2, 2025.
So, if you want to unlock the Chrome-Atose Blueprint in Black Ops 6 and Warzone, make sure to do so before the event concludes. Once it ends, you won’t be able to get your hands on it anymore.
That covers just about everything that you need to know to unlock the Chrome-Atose Blueprint in the latest Call of Duty games. It looks quite premium and also features a decent set of attachments. So, don’t wait for another second, and make sure to claim it now!
