X-58 Nyx - Submachine Gun specs

X-58 Nyx at a glance

X-58 Nyx is one of Activision’s 5 launch submachine gun entries. The official roster contains 33 weapons: 24 Primary Weapons, eight Secondary Weapons and one Melee Weapon. That total excludes Tactical and Lethal equipment, older cosmetic labels and duplicate Blueprint variants. This record uses the October 19 launch article, checked October 26, rather than treating earlier Beta cards as the current specification. Nyx has an integrated suppressor in the launch description. Void adds subsonic concealment behavior and blocks Barrel and Ammunition attachments. The article contains a typo in its skull-hiding phrase; this record does not expand that wording into a new sensor immunity or minimap rule.

In-game description

Backed by illicit funding, the unique X-58 Nyx is an advanced 5.8x21mm SMG designed for covert operations. Featuring an integrated suppressor with a titanium-core battle system, it offers superior sound reduction and dependable close-to-mid-range performance.

The publisher’s description above explains the intended role of X-58 Nyx. It should be read alongside its own numeric block: 53 weapon levels, 40 base rounds, 120 reserve rounds and 800 RPM. These are published fields, not measurements made by this wiki. Descriptive terms about power, stability or speed do not establish a damage table, a time-to-kill result or a tested advantage against a particular opponent. The configuration and mode still matter when interpreting such claims.

How it fits the class

ISO Nightshade provides a same-class reference: its launch block lists 30 rounds, 90 in reserve and 923 RPM. X-58 Nyx lists 40 rounds and 120 in reserve. Compare these base configurations before adding an Apex or a capacity attachment. A larger ammunition count describes ammunition available before replenishment; it does not establish more kills, a faster reload or better handling. Other class members are linked below so this comparison remains part of the complete roster.

Ammo and supply

The official launch reserve for X-58 Nyx is 120 rounds, separate from the 40 loaded rounds. Reserve is ammunition outside the current magazine or feed, not a magazine attachment to add to its capacity. This entry does not infer a pickup amount, resupply interval or shared ammunition pool from a cartridge name. In DMZ, access and replenishment depend on the deployment and FOB systems; the article’s launch reserve field does not locate a specific ammunition cache or promise the same inventory after looting.

Magazine options

The launch block supplies 40 base rounds for X-58 Nyx. Its attachment categories are listed separately below, and the article does not enumerate every magazine capacity or reload duration. Do not add a chambered round to the published figure or import an extended magazine from an older game. Any Apex description that explicitly changes the feed or capacity describes a different configured weapon. Keep the original base count visible so a later build comparison can distinguish the source specification from the selected attachment setup.

Gunsmith attachment slots

The published categories for X-58 Nyx are Optic, Muzzle, Barrel, Underbarrel, Magazine, Rear Grip, Stock, Laser, Ammunition. Its Apex is X-58 Void. The pinnacle of stealth warfare, this subsonic modification produces an exceptionally quiet report, hides skills on enemy deaths, and minimizes direction hit indicators to keep your attacks concealed. Blocks Barrel and Ammunition Attachments. Apex Attachments are equipped separately and do not consume an ordinary attachment slot, but the source may explicitly block individual categories for a conversion. Read those restrictions before planning a combination. Weapon progression unlocks shared attachments for compatible weapons, while Weapon Prestige relocks attachments on the weapon being Prestiged. The Gunsmith reference explains that progression context.

October 28, 2026 tuning changes

What is not measured yet

Infinity Ward states that Multiplayer and DMZ have bespoke tuning. Record the mode, patch date and exact configuration when measuring damage, recoil, effective range or time to kill; published cyclic rate alone cannot supply those results. The October 23-25 patch notes distinguish implemented fixes from proposed future tuning.

How to unlock it

X-58 Nyx’s Main Player Levels unlock table lists Player Level 46. The same article’s individual Available Criteria block instead says Player Level 34. Both values are preserved here because the official source conflicts; confirm the current requirement in the in-game Progression menu before planning around either number. Create-a-Class opens at Player Level 4. In DMZ, unlocked weapons can be purchased through the FOB Gunsmith with sufficient DMZ Cash; looting, Weapon Manuals and the FOB Vendor provide other acquisition routes described by Activision. A cosmetic Blueprint name is a separate entitlement, rather than a replacement for these base progression rules.
