Zero Company weapon mods explained

A weapon has four attachment slots — Barrel, Cell, Scope and Stabilizer — and four mod lines compete for each one. Every step in a line does the same thing at a bigger number, so the choice that matters is which of four effects you want in a slot. Slot count rises over the campaign to at least four. Mods are bought from the Black Market with Credits or earned from Operations and Tactical Missions, and are swapped freely between missions rather than consumed. Sixty-four mods are named; most have no published value, and none of the missing numbers is guessed at here.

The system, as far as it is confirmed

Every weapon has a set number of Modification Slots, and that number can be increased over the course of the campaign. Mods slot into them, change the weapon's statistics, and can carry distinct effects on top of the stat change. Fitting one is not consumption: mods move between weapons and between missions freely, and a fitted mod is visible on the weapon model.

A pre-release trophy asks the player to equip four Weapon Mods to a weapon. That proves four fit simultaneously. It does not prove four is the ceiling, and the difference matters when you are deciding whether a fourth slot is the last upgrade worth buying.

Sixteen lines, four to a slot

The system has a shape, and knowing it is worth more than knowing any individual mod. Each of the four attachment slots holds four **lines** of mods, and every step in a line does the same thing — only the number changes. So there are sixteen distinct effects in the game and sixty-four items expressing them, and the decision you are making in a slot is a choice between four effects rather than between dozens of items.

**Barrel** is raw output and tempo: close-range damage, critical damage, stripping enemy Defense on hit, and a chance to give back an Action Point after attacking. **Cell** is conditions and statuses: damage on the first turn of a fight, Burning stacks, anti-droid and anti-shield damage, and Shock. **Scope** decides whether a shot lands and how well: the range penalty, critical chance, the enemy's Cover, and Assist Damage. **Stabilizer** pays you for how you play the turn: Defense after attacking, damage for not having moved, damage that builds as you keep firing, and a chance at Evasion when you fire.

Two of those pairings settle the buying order for a whole build. Critical *chance* is a Scope line and critical *damage* is a Barrel line, and the damage one is worth close to nothing until the chance one is bought — every weapon in the game criticals 5% of the time unmodified, so a +6 critical damage mod on a bare build pays out about one shot in twenty.

Which mods are best, and what can honestly be said

The lines can be compared; the individual steps mostly cannot, and it is worth being precise about which is which. Sixteen lines have a published span — what the effect is worth at its weakest and its strongest. Eleven individual mods have a published figure. The other fifty-three named mods have neither, and **this site does not interpolate them**, because three lines are demonstrably not evenly spaced: the Condenser line spans +2 to +6 and its two middle steps are +3 and +4, and the Tracking line goes +1, then +2, then up to +8.

So a ranked list of the *lines* is defensible and a ranked list of the *items* is not. On the lines, the strongest case belongs to Scope's critical chance: every weapon starts at 5%, and a line running +6% to +15% is between doubling and quadrupling that, available to any class, and larger than the Gunslinger's own Keen Eye passive.

The rule that decides most of the rest is attack frequency. A per-hit or per-attack effect is worth roughly three times as much on a Blaster Pistol firing three times a turn as on a Longarm firing once — which puts Burning, Shock, anti-shield damage, the Evasion chance and the stacking Ergonomic damage on the Pistol, and puts first-turn damage and critical damage on the Longarm. The same slot rewards opposite weapons depending on which line you fit, which is the single most useful thing to understand about mods.

Two published figures contradict their own line's span, and neither has been quietly resolved here. The Hypercharge Capacitor is +5 in a line published as +2 to +6, at the second of four steps. The Ion Modulator's in-game item card reads +16 against Ray Shields in a line published as +1 to +4. Both are shown with the conflict named.

A mod can be a build, not a modifier

The most build-relevant thing known about the system is that at least one mod applies Burning on hit, and Burning stacks. That takes mods out of the category of small percentage adjustments and into the category of things you build a character around.

A previewer did exactly that: they respecced Hawks out of Scoundrel and into Gunslinger because they had a mod that ignited the target on every attack, and the Gunslinger fires more often than anything else in the game. That is the clearest available evidence that mod choice can be worth more than class choice — the mod stayed and the Specialization moved.

The interaction generalises, cautiously. Any on-attack effect is worth more to whoever attacks most, so the Gunslinger's Onslaught stacking and its refund-on-kill point the same direction as a stacking status. That reasoning is why the Gunslinger Burn build exists, and why it is labelled theorycraft: nobody has published a stack cap, a damage-per-stack figure, or whether an attack that fires twice applies the status twice.

Where the list came from, and what it is worth

This page carried the opposite paragraph for a fortnight: there was no list of mods here because no source named one, and a table of unnamed rows reads as coverage rather than as honesty. That held until 2 September, when a bylined guide published the sixteen lines with their slots and spans, and a community tool that extracts its data from the retail build filled each line with four names.

The tool is unbylined, which normally makes it a research lead here and never a citation. It is cited because it agrees on five separate checkable points with sources that are bylined — including two figures this site had already recorded from unrelated guides, which land exactly on the two ends of one line's published span. That is corroboration rather than trust.

What it buys is the list and not the values. Every mod in the game is named on this site now; most of them are a name, a line and no number, and each is shown that way rather than filled in.

And there is no armour

A mod goes on the weapon. There is no armour slot in this game and no armour mod — an Operator equips a weapon, up to four Weapon Mods and up to three Utilities, and that is the whole loadout. Armor appears on the character sheet as a statistic beside Health and Defense, not as a thing you equip.

Armour sets exist and are cosmetic: Phase I and Phase II clone designs in the base game, ARC Trooper in the Deluxe edition, all changing appearance and colour channels rather than statistics. The armour-flavoured equipment that does have an effect — the Underlays — occupies a Utility slot like a grenade does.

Confirmed

The rules as officially stated

  • Each of the four attachment slots — Barrel, Cell, Scope and Stabilizer — holds four lines of mods, and the steps within a line share an effect and differ only in value.
  • There is no armour slot. An Operator equips a weapon, up to four Weapon Mods and up to three Utilities, and nothing else.
  • Each weapon has a set number of Modification Slots, and that number can be increased over the campaign.
  • Weapon Mods alter a weapon's stats and can apply distinct effects of their own.
  • At least four Weapon Mods can be equipped to one weapon at once — a pre-release trophy requires it.
  • Mods are bought from the Black Market with Credits, and earned from Operations and Tactical Missions.
  • Mods are swapped freely between missions rather than consumed on fitting, and a fitted mod is visible on the weapon model.
  • At least one mod applies Burning on hit, and Burning stacks.
  • A previewer changed an Operator's Specialization specifically to exploit a mod's on-attack effect.

Planning

What this means for squad building

  • Choose the line before the item. Four lines compete for a slot and every step in a line does the same thing, so the decision is which effect you want there — the step is just how far the campaign has taken you.
  • Buy critical chance before critical damage. They are in different slots, and the Barrel line that adds critical damage is close to worthless until the Scope line that adds critical chance has been fitted.
  • Treat an on-attack mod effect as an attack-frequency multiplier. It is worth the most on whichever Operator acts most often in a turn.
  • Do not plan around exactly four slots. Four is a proven floor, not a published cap.
  • Because mods move freely between missions, a strong mod is a squad-wide asset rather than one Operator's equipment — fit it to whoever the mission needs it on.
  • Credits spent at the Black Market compete with everything else the Den wants them for, so mod acquisition is a campaign-economy decision as much as a loadout one.

Still unverified

The retail game is out. These are the points we have not yet reproduced or measured reliably enough to state as fact — recorded rather than guessed at.

  • What most individual mods are worth. Sixteen lines have a published span and eleven mods have a published figure; the other fifty-three named mods have neither, and none has been estimated from the ones around it.
  • Whether a line's steps are evenly spaced. Three lines say no, which is why nothing here is interpolated.
  • How many slots each weapon type starts with, and what raises the count.
  • Whether the maximum is four or higher.
  • Burning damage per stack, the stack cap, and its duration.
  • Whether the Burning mod triggers per attack or per hit, and whether a multi-projectile attack applies it more than once.
  • Whether any enemy resists or is immune to mod-applied statuses.
  • Whether mods have rarities, and whether rarity gates which weapons accept them.

Questions

Common questions

The way these come up in search, answered directly.

How many Weapon Mods can you equip on one weapon?
At least four — a pre-release trophy requires it. Whether four is the maximum has not been published.
What do Weapon Mods do in Zero Company?
They slot into a weapon, change its stats, and can add effects of their own — one applies stacking Burning on every hit.

The structural claim, verbatim: "Each category of weapon mods…includes four different types or lines of mods on various tiers. The effects stay the same on the different tiers, except for the range of their values." Then four slots with four lines each, each line given an effect, a published span and the mod the guide names as the top of it.

The fourth it calls STABILIZER, which matters because the community catalogue calls that same slot Stock. **Checked for and absent**: any per-step name below the top of a line, any rarity, any acquisition source, and any statement of how many tiers a line has beyond "various".
