Active Matter Carefully Selected, Explained

Short answer: the purple words on an Active Matter weapon - Lightweight, Adjusted, Balanced, "Carefully Selected" - are hidden bonuses the item already carries, and you read them by holding Alt with your cursor on the weapon, which highlights the actual bonus in green. They are not mods you installed, they are not cosmetic flavor, and as of 2026-10-11 there is no documented way to apply or reroll them yourself.

The confusion is understandable, because the game never explains the system. A player who kept finding guns marked "adjusted, balanced, carefully selected" with no visible mods asked about it on the game's Steam forum and noted there was zero information anywhere - and the thread is still the closest thing to official documentation. What follows is what players have established so far, labelled by source.

What the purple text is

Players have reported at least four of these trait words so far: Lightweight, Adjusted, Balanced and Carefully Selected. They appear in purple text on weapons found in raid, they are not tied to any installed mod, and two weapons with the same base model can carry different words. The words are labels for an underlying bonus rather than the bonus itself - the Alt view is where the real stat change shows up. (community-sourced; the full list has never been published by the studio, so treat these four as reported examples, not a complete catalogue)

One practical note from the same thread: because the words are only a label, searching for a single word like "Carefully Selected" is the wrong way to look up what your gun does. The Alt-inspect view is the authoritative readout on your specific item.

How to read the bonus

1. Hover your cursor over the weapon in your inventory.
2. Hold Alt. The item card expands to its full information.
3. The bonus is highlighted in green text - players describe effects like reduced weight or improved accuracy, varying by item. (community-sourced; single player report, but trivially verifiable in game)

That is the entire mechanic. There is no crafting step, no consumable and no menu involved in seeing the trait.

Why you cannot apply them yourself (yet)

The second half of the story is a feature request. A separate Steam thread asks for a weapon-tuning system that would let players craft these bonuses onto weapons deliberately, comparing it to The Division's resource-upcycling perks. The studio has not replied to that thread, and no official source - store page, news feed or in-game text - describes a way to add, remove or reroll a trait as of 2026-10-11.

So if you are comparing two guns, the honest read is: the purple text is a bonus you got, not one you chose. Anything claiming to teach you how to "get" a specific trait is speculation, because the acquisition rules have never been documented by anyone, including us.

What to watch next

The trait system is exactly the kind of thing a looter shooter formalizes in a patch - either as an inspect UI change or as a tuning bench. The official news feed is where build numbers appear first, so if the studio ships a weapon-tuning system, it will show up there before any wiki summarizes it. Until then this page stays deliberately short: four reported trait names, one verified way to read them, and nothing invented to fill the gaps.
