Star Wars Zero Company Weapon Upgrades are split across three different systems: removable Weapon Modifications in the Armory, permanent Weapon Optimizations for an Operator’s signature weapon, and roster-wide upgrades bought through The Den’s Upgrade Facility. Understanding the difference prevents you from spending Credits on the wrong layer.
The most important rule with Star Wars Zero Company Weapon Upgrades is that a mod, an Optimization and a company-wide weapon upgrade are not the same thing. Mods can be swapped into available slots, Optimizations permanently improve a signature weapon, and Upgrade Facility purchases improve the relevant weapon class across Operators who use it.
All three types of Star Wars Zero Company Weapon Upgrades
| System | Where | What it changes |
|---|---|---|
| Weapon Modification | Armory | A specific weapon’s stats or unique effects |
| Weapon Optimization | Armory / signature weapon | Permanent power or stat improvement for that Operator’s signature weapon |
| Roster-wide Weapon Upgrade | Upgrade Facility | Permanent improvement for all Operators using the named weapon class |
The systems stack rather than replacing one another. A character can benefit from a company-wide weapon-class upgrade while also carrying a modded and Optimized signature weapon.
Weapon Modifications in Star Wars Zero Company Weapon Upgrades
The Armory lets you install Weapon Modifications that alter stats or add specific effects. Every weapon has a limited number of mod slots, and The Den can unlock an Additional Weapon Mod Slot for the roster.
Mods are the flexible layer. Swap them when the mission or build changes instead of treating every equipped mod as a permanent commitment.
Weapon Optimizations in Star Wars Zero Company Weapon Upgrades
Weapon Optimizations apply to an Operator’s signature weapon and permanently improve its power or stats. Only one of each Optimization type can be applied, so the choice deserves more thought than a removable mod.
Check the exact live effect before confirming. A permanent Optimization should reinforce what the Operator already does well rather than solving a problem that belongs to another squad member.
Roster-wide Star Wars Zero Company Weapon Upgrades
The Upgrade Facility sells weapon improvements that apply to the relevant class across the company. That makes them valuable when several regular Operators share the same weapon family, because one construction improves more than one character.
The available stat categories depend on the weapon class and Den progression. Damage, range, critical performance and Overwatch can all matter differently for Longarms, Pistols, Repeaters and other weapon types.
How Modification Slots work with Star Wars Zero Company Weapon Upgrades
Each weapon begins with a limited number of spaces for mods. Purchasing the Additional Weapon Mod Slot upgrade increases that capacity for all Operators, letting more modification effects be equipped at the same time.
That roster-wide slot can be more useful than one small class upgrade early on because it expands build flexibility across every weapon-bearing Operator.
Where to get mods for Star Wars Zero Company Weapon Upgrades
Completing Operations and Tactical Missions can reward Weapon Modifications and Optimizations. The Black Market also sells Weapon Modifications and Utilities, with stock refreshing every Cycle.
Check the market after a Cycle if you are missing one specific mod family. Selling or ignoring useful flexible mods too early can make later builds harder to assemble.
Best Star Wars Zero Company Weapon Upgrades to buy first
Prioritise the weapon classes used by several members of your regular squad, then consider universal capacity upgrades such as the Additional Weapon Mod Slot. A permanent improvement to a class nobody currently deploys is difficult to justify early in a campaign.
Long-range squads benefit more from upgrades that improve hit quality and range, while close-range or high-volume weapon users may gain more from direct damage or critical effects. Match the upgrade to the way the weapon is actually being used.
Do Star Wars Zero Company Weapon Upgrades change AP costs?
Weapon Classes have their own AP patterns, and a weapon upgrade should not be assumed to change those costs unless the live effect specifically says it does. Mods and stat upgrades normally improve performance rather than rewriting the base action economy.
Plan AP around the weapon class first, then use upgrades to improve what those attacks accomplish.
Best way to use Star Wars Zero Company Weapon Upgrades
Use removable mods to adapt from mission to mission, permanent Optimizations for signature weapons you know you will keep using, and roster-wide upgrades when several Operators benefit from the same class investment.
Star Wars Zero Company Weapon Upgrades become much easier to manage once those three layers are separated. Armory mods are flexible, Optimizations are permanent individual investments, and Upgrade Facility purchases are long-term company upgrades that can improve an entire weapon family at once.
