How do you unlock the Combat Knife?

The Combat Knife unlocks at Multiplayer Level 37 in Call of Duty: Infinite Warfare. It is a standard contact melee weapon: It trades every ranged option for an immediate close-contact takedown. Use that stable behavior rather than relying on patch-sensitive damage claims. Its camo track finishes at Neon Tiger (Get 3 kills without dying 10 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.

Camo rarity and catalog membership were checked against the complete camouflage record; editorial setup advice avoids patch-sensitive numeric claims.

How does the Combat Knife play in Infinite Warfare?

Rolestandard contact melee weapon
Real-world basisFictional Infinite Warfare weapon; no one-to-one real-world model is asserted.
StrengthsThe Combat Knife has a clear standard contact melee weapon identity; It trades every ranged option for an immediate close-contact takedown
TradeoffsA visible approach through a watched lane has no correction; Its melee weapon role still depends on choosing the correct route and first engagement
Setup notesUse concealment, movement and route timing to reach contact range; Avoid a straight approach through a watched lane because there is no ranged correction
Challenge noteComplete the 14 Multiplayer challenge camos on the Combat Knife for Gold. Its Diamond unlock is the special secondary-weapons exception: earn Gold on the four original handguns, three original launchers and the Combat Knife. That completion counts toward the original 35-weapon Black Sky route.
Progression tipGold is earned on the Combat Knife itself, but Knife Diamond requires Gold across all original non-Classic secondary weapons rather than only the one launch melee weapon. Solar then covers every original non-Classic category, and Black Sky adds all six original Classic weapons.
Camo tipUse corners, thrust routes and timing to arrive outside the opponent's sightline.
Compared withThe later Axe adds a throwable Epic variant; the Combat Knife is the launch mastery weapon.

Combat Knife — common questions

How do you unlock the Combat Knife in Infinite Warfare?

The Combat Knife unlocks at Level 37 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 Combat Knife?

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 Combat Knife the final tier is Neon Tiger — Get 3 kills without dying 10 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.
