How to unlock the World Ender blueprint in MW3 and Warzone for free?

The World Ender blueprint in MW3 and Warzone is a free weapon blueprint for the FR 5.56 Assault Rifle. It was added to the shooters in Season 4 and is a part of the new limited-time event called "Critical Countdown." The blueprint gives the FR 5.56 an animated green makeover with many dynamic elements on the body such as a progress bar and a radar, making it stand out from other camos for the gun.

That's not all about the aesthetics, though. Since it is a blueprint, it comes equipped with attachments that optimize the weapon for low recoil and assist the player with the gun kick control.

Having said that, in this brief guide, we'll take a closer look at how you can unlock the World Ender blueprint in MW3 and Warzone.
