Attachments

An attachment changes the stats of the weapon it’s fitted to: it always brings a measurable upside and a downside (for example a bigger magazine but a slower reload). You fit them in the Gunsmith, outside of matches; the saved build then applies every time you get the weapon, from a wall, from the Mystery Box, from your loadout or after the Forge of Ys. The Gunsmith opens at level 6 (see Levels, ranks and prestige); your weapons earn their levels and attachments from the very start.

Wonder weapons, the knife and the Gatling take no attachments.

Slots#

Each weapon has its own list of compatible attachments, spread over nine slots. A slot only holds one attachment at a time.

Five attachments at most#

A weapon carries five attachments at most, however many slots it has. The Gunsmith shows the counter; to add a sixth, remove one first. So pick the slots that really fix the weapon’s weakness.

Unlocking attachments#

Attachments unlock weapon by weapon, as you raise the weapon level:

• each weapon has its own unlock order: the first attachment on its list comes at level 2, the next at level 3, and so on, one per level;
• a weapon’s max level is its number of attachments + 6: the last attachment therefore arrives a few levels before max level;
• weapon XP comes from kills with that weapon (60 XP, +40 for a headshot, more on Realistic difficulty, and doubled by a Double Weapon XP token). See Armory, Gunsmith and loadouts.

In the Gunsmith, the Next unlock line shows the next attachment and the level it needs. New attachments are also announced on the end-of-match screen.

Optics#

• Non-magnified sights (red dot, holographic, Kobra, mini reflex, Mk.III reflector): clear sight picture, a little extra accuracy, barely slower ADS. The right default choice at short and medium range. When you aim, the sight window fills a large part of the screen and its glowing reticle stays on the target, even when the weapon moves.
• Iron sights (aperture, tritium): almost no magnification, but faster ADS than the weapon’s original sights.
• Combat scopes (ACOG, holo with 3× magnifier, ZF41): medium magnification, slightly slower ADS.
• Precision scopes (4×, 8×, 10× mil-dot, M84, PU, PSO-1): a big accuracy gain, but slow ADS and more flinch when you’re hit. Some only exist on a few weapons (PSO-1 on Soviet weapons, 10× on the M40A5 and the Barrett).

A non-magnified sight (or the holo with magnifier) replaces the original sights: the weapon’s rear and front sights are removed, so nothing stands in its window when you aim. On weapons with a carry handle (M249, PKM, Galil, AA-12), it is folded down or taken off. With a scope, the front sight stays on the weapon: the eyepiece hides it when you aim. The aperture and tritium sights keep it too: they line up on it.

Inside the scope#

Every magnified optic is simulated: when you aim, the weapon and its scope stay on screen and the magnification happens inside the eyepiece. Around the scope, the world keeps its normal scale: you still see what is coming from the sides, just without the zoom.

• Your eye is never perfectly on the axis: when the weapon kicks, moves or is not shouldered yet, a crescent of shadow slides in from the edge of the eyepiece, then fades. The reticle follows the weapon’s axis.
• With a precision scope, hold the sprint key to hold your breath for a few seconds: your aim steadies. Once you run out of breath, it shakes more while you recover.
• Every scope has its own reticle: pointed duplex (4×), fine ranging crosshair (8×), mil-dot (10×), post and horizontal wire (M84), three posts (PU), illuminated chevrons and rangefinder (PSO-1), chevron and holdover marks (ACOG).
• The centre of the 4×, 8× and 10× reticles is lit in red: it stays readable on a target in the shadows. Period scopes (ZF41, M84, PU) keep a black reticle, harder to read in complete darkness.

Thermal and infrared#

Two scopes show a different image in their eyepiece:

• the Thermal scope shows a “white hot” thermal image: silhouettes stand out sharply from the scenery, even through fog and smoke;
• the Vampir infrared scope, exclusive to the StG 44, is a 1945 night scope: in the green glow of its converter, the Drowned stand out from the dark. Its infrared lamp is heavy and slows you down.

Both are slow to aim: keep them for holding a sightline, not for close quarters.

Build tips#

• SMGs: extended or dual mags, laser sight, grip tape or a light stock for handling, hollow points for damage.
• Assault rifles and LMGs: vertical grip, compensator or muzzle brake against recoil, a low-magnification sight, FMJ rounds to go through more zombies.
• Tactical and sniper rifles: FMJ rounds to line up headshots, a long or heavy barrel for range, and an optic that suits the map (metro corridors don’t call for a 10× scope).
• Shotguns: the choke tightens the spread and extends range; an extended mag means fewer shell-by-shell reloads.
• The suppressor reduces effective range; keep it for weapons that kill up close.

Skin pieces#

Skins with their own model (shop, ultimate reward of a pass) replace parts of the weapon with sculpted pieces: the scythe blade of The Ankou’s Scythe or the menhir of Night of the Korrigans. Each piece counts as an attachment:

• it takes its slot and one of the five places;
• it has exactly the effects of an existing attachment (for example, every muzzle piece has the compensator’s effects);
• it needs no weapon level, but only works with its skin, on its weapon;
• fitting another attachment in the same slot puts the weapon’s original part back.

When you equip the skin, its pieces fill the free slots, up to the five-attachment limit. Skin details: Camos.
