How do you unlock the R3K?

The R3K belongs to the starting Create-a-Class weapon pool in Call of Duty: Infinite Warfare. It is a precision energy burst rifle: Each press sends a fixed energy burst that rewards complete first-burst placement. Use that stable behavior rather than relying on patch-sensitive damage claims. Its camo track finishes at Neon Tiger (Get 3 kills without dying 20 times). Complete every camo challenge on it and Gold unlocks. Earn Gold on every camo-eligible launch weapon required in its category for Diamond. Complete the required base-game class mastery route to earn Black Sky.

Weapon ranks, mechanics and the mastery sequence were reconciled against dedicated historical references. Camo rarity and catalog membership were checked against the complete camouflage record; editorial setup advice avoids patch-sensitive numeric claims.

How does the R3K play in Infinite Warfare?

Roleprecision energy burst rifle
Real-world basisFictional Infinite Warfare weapon; no one-to-one real-world model is asserted.
StrengthsThe R3K has a clear precision energy burst rifle identity; Each press sends a fixed energy burst that rewards complete first-burst placement
TradeoffsA missed round creates a correction gap before the next burst; Its assault rifle role still depends on choosing the correct route and first engagement
Useful setupChoose an optic or clean sight picture first, then add control or handling for the lane you actually use; Keep one exit route available instead of building only for a stationary gunfight
Challenge noteComplete the 14 Multiplayer challenge camos on this weapon for Gold. It counts toward the original 35-weapon Black Sky route.
Progression tipGold is earned per weapon, Diamond covers its category, Solar covers the original non-Classic categories, and Black Sky adds the original Classic category. This launch weapon participates in that original scope.
Camo tipSet the reticle before firing and move only after the burst clears.
Compared withThe Type-2 is automatic and transforms; the R3K is built around a clean burst.

R3K — common questions

How do you unlock the R3K in Infinite Warfare?

The R3K is available in the starting Create-a-Class pool once Create-a-Class opens in Call of Duty: Infinite Warfare multiplayer. The level cap is 55, and prestige is 10 standard Prestige levels, followed by Master Prestige progression. Each standard Prestige grants a Permanent Unlock Token; odd-numbered entries also supply Classic Weapon Unlock Tokens.

How do you unlock camos on the R3K?

Camo progress is per-weapon. Desert, Mars, Arctic Tech and Wilderness track initial kills or streak destruction. Mojave through Zebra use class-specific objectives, followed by Autumn, Whiteout, Bengal, Murdered Out and Neon Tiger. Gold is per weapon and Diamond normally covers one category; Combat Knife Diamond instead requires all original non-Classic secondaries, and Classic Diamond requires all six original Classic weapons. Solar covers the original non-Classic categories and Black Sky completes the original Classic step. Quartermaster, Mission Team, Zombies, event and promotional camos are not prerequisites for Gold, Diamond, Solar or Black Sky. On the R3K the final tier is Neon Tiger — Get 3 kills without dying 20 times. After that, Gold needs every camo challenge on the weapon done, and Diamond needs Gold on every camo-eligible launch weapon required in its category, and Black Sky requires mastery across the base-game weapon classes.
