Stats

The sign is read the same way every time: + means better and − means worse, regardless of which way the underlying number moves. +DRAW is a faster draw, −DRAW a slower one. Most stats occur in both directions on real attachments; a dash means that direction has not been seen.

1.2Tiered systems

Almost nothing in this game scales continuously. Stats move in discrete rungs, each buff or debuff shifts you exactly one rung, and the step size shrinks toward the strong end so diminishing returns are built into the ladder itself.

Every stat that has been examined is tiered. Treat an unfamiliar one the same way until something contradicts it.

A step is 17–50ms depending where you sit on the ladder, not a flat amount. +DRAW2 denotes a two-rung gain. The last rung is a single frame, half the gain of every step below it, so the move from 100 to 83 buys the least of any +DRAW on the ladder.

The rungs are ordinal. Actual gains vary by weapon, so a rung is a position, not a magnitude.

Where an attachment improves recoil or hipfire without stating a qualifier it is recorded as +REC1 / +HIP1.

ADS accuracy while moving

The rung values are not published, so this one is mapped by its sources rather than by a ladder. Every attachment granting +mACC moves you one tier better; every attachment carrying −mACC moves you one tier worse.

The range is −3 to +1

Both ends are structural rather than arbitrary.

Two tiers is the reachable maximum: one barrel and one laser, since a second laser cannot be mounted and no other slot grants +mACC. So −3 is modeled but has no known attachment route. Build for −2 and treat −3 as unproven.

The penalty does not stack either. −mACC exists in one slot only: the underbarrel, on 12 of its 21 grips. A weapon has one underbarrel, so +1 is the floor and a single +mACC source cancels it outright. A penalized grip still leaves you at −1 net with both sources equipped, which is the argument for a clean grip on a mobile build.

ADS movement speed

Mapped the same way as moving accuracy, on its own axis. Every +mSPD source moves you one tier better, every −mSPD one tier worse, and the shifts sum.

This is the one stat three separate slots can charge at once, and it has a single counter in a fourth. A high-control, high-capacity, thermal build is three tiers down against one available tier back.

2.1Design rules

1 · Attachment costs are pure arithmetic

Every cost is the sum of its components.

Drawbacks run the same prices in reverse. A drawback listed on an attachment discounts it by exactly what the matching benefit costs to buy. A grip that gives up moving accuracy is 10^† cheaper, which is what moving accuracy costs to add anywhere else. Nothing is hidden in the pricing, and no attachment is a bargain.

^† −SWAY, −VEL, −DRAW and −mSPD discount by 5.

So the game is not finding underpriced parts. It is deciding which drawbacks you can afford to carry, across the slots you have, for the way you actually play.

Where costs vary between weapons

Most attachments cost the same on every weapon that offers them. Muzzles, grips, optics, optic accessories, lasers, lights and ergonomics are fixed, and so are the barrel archetypes. Variance is confined to two places:

Every other ammo type is fixed: Standard ammo and Penetration ammo at 5, Lightweight ammo, Long Range, Range Pen. and Sub. Pen at 10, Frangible at 20.

2 · You cannot buy clean recoil above +REC2, but you can buy it back

Every grip above "slightly reduces recoil" carries −mACC, and +REC4 / +REC5 add −mSPD on top. Within the underbarrel slot, high control and mobile accuracy are mutually exclusive by design.

Both penalties have a counter, and both cost 10 points, in other slots.

^† A 50 MW Blue or 120 MW Blue laser also carries +mACC, but projects a beam.

Neither competes with the grip for space, and both cancel one for one. A single 50 MW Violet laser fully absorbs one penalized grip; adding a Light barrel puts you a tier ahead of base. Lightweight ammo does the same job for −mSPD.

For a mobile build the grip choice costs you a tier of moving accuracy, not just points. Only two +mACC sources exist, so a clean grip caps you at −2 and a penalized one caps you at −1. Whether that tier is worth more than the recoil rung it buys depends entirely on how much of your shooting happens in motion.

Both drawbacks are recoverable, so the ceiling is a spending decision rather than a hard limit. Two routes land on the same total and deliver different things:

Identical cost, because Lightweight ammo is only 5 over the Standard you were paying for anyway. The 6H64 route buys an extra recoil rung and mSPD neutrality; the Canted Stubby route buys +ADS instead. Neither is strictly better, but the idea that high-rung grips are unaffordable for a mobile player does not survive the arithmetic.

Lightweight ammo also satisfies the ammo floor, so its true marginal cost over Standard is only 5.

3 · Moving ADS spread is already 6.4× worse than stationary

Base values are 0.32° moving vs 0.05° stationary. −mACC stacks on an already-bad number, making it more expensive than the tooltip implies. Costly to players who shoot while repositioning, nearly free to players who plant first, and removable outright at three net tiers of +mACC.

4 · Mounting is the only purchasable spread reduction

Measured at roughly 50% recoil and 50% spread reduction while mounted, and it applies whether you are moving or not. No grip comes close: the +REC ladder barely touches precision.

+mACC also reduces spread, but only the moving penalty, and only down to the base stationary figure. Mounting is the only thing that improves on standing still.

The untracked cost is tempo. Mounting takes roughly a second to mount, settle and fire, and locks you in place. Mountable surfaces are plentiful, but the delay appears in no stat.

5 · Suppressors do not affect muzzle velocity

The datamined Suppressed velocity column is blank for every assault rifle. Suppressors cost hipfire, sway, or points, never velocity or damage.

6 · Four slots have no "None" — every build starts 20 points down

Ammo, barrel, optic and magazine all require a selection. There is no zero-cost option in any of them.

7 · The name is not the attachment — the tooltip is

Attachment names in this game are decoration. They map to effects neither reliably nor uniquely, in both directions.

Different names, same attachment

Same name, different attachments

"Factory Angled" denotes three genuinely different grips at three different prices, and each one is priced exactly right for what it actually does:

Spending a remainder

Builds land on multiples of 5 and frequently come up short by one step. Spend it upgrading something already in the build, not adding a new slot.

Traps worth naming

2.2Muzzles

Thread Protector, Single-Port Brake and Slant Brake are weapon-specific variants of the same part, never available on the same weapon. See Design Rule 7.

Linear Comp is an axis converter, not a downgrade

It reduces horizontal recoil by 20–25% and increases vertical by roughly one rung. Vertical is a learnable pattern; horizontal is a random cone you cannot compensate for.

Take it above ~35° recoil direction variation. Skip it below ~20°, since there's no horizontal left to convert and you just eat the vertical penalty.

The stealth economy

• 10 pts (Flash Hider) → HIDE-3D HIDE-FLASH
• 20–30 pts (any suppressor) → the above plus HIDE-MAP
• Barrel slot on integrally suppressed weapons → HIDE-MAP at 20 or HIDE-MAP+ at 30
• Subsonic ammo + any suppressor → HIDE-MAP+

The spotting diamond is cheap. The minimap costs exactly 10 more.

Flash Comp (20) is the efficient pick when minimap concealment isn't required: it is Flash Hider plus +RBLD, with no drawback. Long Suppressor (25) is Lightened Suppressor (30) with −SWAY accepted for a 5-point discount.

Recoil stacks with the underbarrel, and it is the most expensive thing you can stack. The heaviest available pairing is Compensated Brake (20) plus a +REC5 grip (35): 55 points of a 100-point budget, with 20 already committed to the slot floors. Everything else on the weapon comes out of the remaining 25.

Rarely hipfire → −HIP1 is nearly free, Lightened is best value. Hipfire often → CQB costs you nothing.

2.3Underbarrels

Two grips buy capability, not stats

Underslung Mount (10) enables HE, Thermobaric and smoke grenade launchers to be mounted under the weapon. No stat penalty, and the only cost is forfeiting a grip. This is the largest utility swing available in the slot.

Compact Handstop (10) enables firing while sprinting, with no listed drawback, but it is SMG only. It removes the sprint-to-fire delay entirely, which no amount of +ADS can replicate, and it is the reason an SMG can contest a corner an assault rifle has to stop for.

2.4Barrels

Primitives

Archetypes are named combinations of five primitives, and their costs are the sum.

The barrel slot is where three component prices appear that no other slot exposes: +VEL at 5, +SUSTAIN at 10, and the −5 discount for accepting −VEL or −DRAW.

Archetypes

^† EF88 only.   ^‡ Integrally suppressed weapons, which have no muzzle slot. HIDE-MAP+ cuts minimap spotting to ~9m rather than ~21m.

Extended, Heavy, Heavy Ext. and Suppressed barrels grant no +ADS. Pairing one with an +ADS grip only returns you to where a Basic barrel starts, so the grip buys nothing you did not already give up.

Integrally suppressed weapons buy concealment in the barrel slot

Weapons with an integral suppressor have no muzzle slot. Their barrel archetypes are the suppressor instead.

Every muzzle suppressor cuts minimap spot range to ~21m; the enhanced integral barrel cuts it to 9m on its own, the same figure a suppressor reaches when paired with Subsonic ammo.

2.5Magazines

The one slot with no archetypes. Capacities are weapon-specific and costs scale per weapon family, so a tag set copied from one weapon means nothing on another. The shape is the same everywhere; only the numbers move.

Tags come from each magazine's own description, not from comparing it to the stock one. A magazine that says it handles faster carries +DRAW; one that says nothing about handling carries no tag. Measuring against stock would invert the reading on any weapon whose stock happens to be the smallest option or a FAST variant.

Capacity is the currency

In every other slot you pay points. Here you pay points and capacity together, and capacity is not a tag, which is why a 20-round and a 30-round magazine can both cost 5 while the smaller one is better on every tracked stat.

The FAST variant

Every capacity comes in a standard and a FAST version. FAST always grants +RELOAD, measured at 13% faster, and always costs one −DRAW rung against its standard counterpart. It costs +5 points unless the standard is already sitting on the floor.

2.6Ammo

Like barrels, ammo resolves to archetypes rather than names, and several archetypes are combinations of two others. Most costs are fixed; the four shown as ranges vary per weapon.

Standard ammo

How the combinations price

Penetration is free to add. It costs the same as Standard, so any "Pen." composite costs exactly what its other half costs. Combining two paid types instead sums them: Sub. HP is Subsonic plus Hollow Point at full price.

Penetration penalties do not stack. Subsonic and Hollow Point each carry −PEN; Sub. HP carries one, not two. And because Penetration's +PEN cancels Subsonic's −PEN, Sub. Pen is the only way to get spotting reduction without a penetration cost.

When Synthetic is offered, it is priced 5–10 points higher than Hollow Point on that weapon.

Spotting ranges

Subsonic exposes the baseline the concealment tags are measured against. These figures are identical on every weapon.

This is the same 9m the enhanced integral suppressor barrel reaches, so HIDE-MAP+ is not exclusive to integrally suppressed weapons.

Headshot multipliers

Base headshot multiplier varies by weapon, and so does what Hollow Point and Synthetic do to it. There is no universal figure; read them per weapon.

These multipliers cross kill breakpoints, and which one you need is weapon-specific: the jump from +HEAD to ++HEAD can convert a 4-shot kill into a 3-shot kill at a range where the smaller multiplier falls short. Always compute against the weapon's damage table.

Penetration is one axis, traded in both directions

Nothing gives both headshot damage and penetration. −PEN is near-free when shooting exposed targets one at a time and real when working through cover.

Shotgun ammo

2.7Optics

Magnification does not affect cost: a 10-point 8.00x sits alongside a 10-point 1.00x. What you pay for is capability, and the slot has six.

2.8Optic Accessories

Your optic covers one range band. Most of this slot adds a second, from whichever end the optic is missing.

2.9Accessories — Lasers, Lights and Rangefinders

Mounting position varies by weapon: the same laser sits on the right rail of one gun and the top rail of another. Position is not slot type.

A weapon can have more than one accessory mount, so running a light and a laser simultaneously is possible. How many mounts you get is weapon-specific. Accessories do not share space with the underbarrel.

Lasers

Color sets the function, wattage sets the rung, and visibility is the price.

Blue lasers are Green plus +mACC for 10 points at both rungs. 5 MW Red trades hipfire for a shorter beam; 50 MW Violet spends its 10 points on +mACC instead of hipfire.

What "visible" actually means

VISIBLE means the laser projects a beam into world space, readable by enemies for roughly 5m in front of you. The practical cost is positional: a beam can round a corner before you do, or spill through a doorway you have not stepped into yet. For anyone playing slowly and holding angles, that is a real tell: it announces where you are about to be.

Every laser is noticeable on the weapon itself, including 5 MW Red and 50 MW Violet. Looked at directly from any range, the emitter is bright and obvious. VISIBLE is not the difference between hidden and seen: it is the difference between betraying yourself around cover and only being visible once someone already has eyes on you.

So 5 MW Red and 50 MW Violet are the positionally quiet options rather than invisible ones. If nothing on the build depends on the enemy failing to notice your gun, the 20–30 point tier is not disqualified; it just costs you the corner.

Lights

Every light grants one stage of +HIP-RBLD. What you pay beyond that is when it turns on: Taclight — Aimed is dark while hipfiring, so it never delivers the recovery at all, and its 5 points buy the automation alone.

Taclight — HIP is the concealment-aware option for anyone who holds angles: lit only in close quarters where you are likely already spotted, dark whenever you are aimed in at range. The 5 points over the Flashlight buy the automation, not the light.

Laser/light combos

A light and a 5 MW laser on one mount, priced as the sum of both.

Both price as the light plus the laser: Red is 10 + 10, Green is 10 + 20 − 10.

Rangefinders

2.10Ergonomics

The most functionally varied slot in the game. Several entries change how the weapon operates rather than adjusting a stat.

^† Offered on a handful of weapons only.   ^‡ Every sniper except the Mini Scout.

Aftermarket Buffer (5) reduces screen shake and sight movement without changing any underlying value. Nothing about the bullets changes, but you can see your own impacts and correct mid-burst.

Magwell Flare (10) and DLC Bolt (30) are the same feature split by class: reload without leaving your sight picture.

Three entries change or tune the weapon's fire mode, and all three are weapon-specific. A3 Receiver (25) converts a semi-auto to full auto and appears on the M16A4 alone. Burst Training (15) adds burst, and Match Trigger (15) improves an existing semi-auto. Both are scattered across a handful of weapons. You are rarely choosing between them; on most weapons none are offered at all.

3.1Weapon cards

Every automatic weapon in the game, stock, derived from its own ballistics data rather than from stat bars. The bar shows shots to kill by range.

The ADS and HIP markers are the same measurement: the range at which half your shots still land on a torso, taken on the last shot of a kill rather than the first. Past it the weapon still fires, it just needs more rounds than the strip says. The shaded band is the hipfire cone widening as you shoot, solid where it can reach full width and still hit, fading out to where only an opening shot lands.

Before you spend anything

Three things about the weapon decide the build before you have spent a point, and none of them appear on the attachment screen. Reading them costs nothing and settles most of what follows.

The cards below carry all three for every automatic weapon: the damage strip, the squirreliness figure and the spread figure.

Squirreliness says whether recoil spending helps, Climb says how much there is to fix, and Spread says whether either one is the limit.

The track under each number shows where it sits across all 38 weapons, left for low. It marks position rather than quality: a weapon sitting right on all three is a close-range weapon, and none of the three costs it anything inside its own band. Compare the three tracks against each other. The one furthest right is where points are worth spending; the others are already handled.

Stat families split by range

The target shrinks with distance while every angular penalty stays the same size. That splits the tag vocabulary into three groups that do not compete with each other.

+mACC is worth most on weapons that are already accurate. On a squirrely weapon the moving penalty hides under the weapon's own dispersion; on a tight one it is the dominant error term, so removing it is most of the fix.

Named counters

Each weakness has one attachment that answers it directly. The trigger column is read off the card.

Linear Comp and the high grips separate cleanly. Squirrely weapons want the muzzle, high-climb weapons want the grip. Only a handful want both, and none can afford both.

4.2Open questions

1. Per-weapon magazine tables beyond the assault rifles: LMG belt boxes, shotgun shell tubes and sniper speedloaders sit in very different capacity bands
2. Optic-to-accessory availability, which specific optics a given weapon offers the Magnifier or Piggyback on
3. Long Range ammo's drag magnitude: the effect is confirmed, the size of it needs ballistic testing at range
4. The third +mACC source. The tier system bottoms out at −3, where moving spread equals stationary, but only two sources exist across all nine slots. Whatever reaches the last rung is outside the attachment system
