How do you unlock the G-Rail?

The G-Rail was added after launch; its original access was Season Pass grant; otherwise complete 20 matches with at least five hip-fire Stallion .44 kills in each; an eligible variant also unlocked the base in Call of Duty: Infinite Warfare. It is a charge-capable burst energy rifle: It combines an automatic burst cycle with a charge mechanic and integrated optic. 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. Its Gold does not count toward the original Diamond requirement; both this weapon's Gold and the launch-weapon class requirement must be complete before Diamond can be equipped on it. This post-launch weapon does not increase the original Black Sky requirement; its own camo challenges and the account-wide base-game mastery route must both be complete to equip Black Sky.

How does the G-Rail play in Infinite Warfare?

Rolecharge-capable burst energy rifle
Real-world basisFictional Infinite Warfare weapon; no one-to-one real-world model is asserted.
StrengthsThe G-Rail has a clear charge-capable burst energy rifle identity; It combines an automatic burst cycle with a charge mechanic and integrated optic
TradeoffsA mistimed charge or missed burst creates a visible correction window; 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 does not expand the original Solar or Black Sky requirement, but its own Gold is needed before those finishes can be equipped on it.
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 post-launch weapon does not increase either original account-wide total.
Camo tipCharge from cover only when the lane will remain open through release.
Compared withThe R3K is a three-round burst; the G-Rail adds a fourth round and charge behavior.

G-Rail — common questions

How do you unlock the G-Rail in Infinite Warfare?

The G-Rail was added post-launch to Call of Duty: Infinite Warfare through a post-launch weapon. Platform availability is listed on this page. 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. Historical post-launch access; current availability depends on the platform service, account entitlements and Quartermaster inventory.

How do you unlock camos on the G-Rail?

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 G-Rail the final tier is Neon Tiger — Get 3 kills without dying 20 times. After that, Gold needs every camo challenge on the weapon done. This post-launch weapon does not count toward the original Diamond total, but its own Gold and the launch-weapon class requirement must both be complete before Diamond can be equipped on it. It does not increase the original Black Sky requirement; this weapon's camo challenges and the account-wide route must both be complete to equip it.
