Select Weapon Variants in Infinite Warfare are exclusively unlocked via Supply Drops

In addition to all of the weapons in the Prototype Lab, which players are able to directly craft or earn via Supply Drops, there is another set of limited number of weapon variants in the QR-M5TR Collection.

All of the weapon variants in this collection can only be obtained via a Supply Drop or a Zombies Crate, and players can only equip these variants once they reach the level needed to equip each one.
