Weapon amplification lets you specialize compatible firearms in ARC Raiders with upgrades that change how they handle and perform. Introduced in the Frozen Trail 2.0 update, the system offers paths for sustained fire, close-range armor damage and precision shooting.
If you are deciding where to spend your materials, start with a weapon you already use regularly. The Rattler Drum Mag is an accessible option for sustained fire, while Il Toro Slug Rounds suit close-range ARC encounters. The Bettina, Osprey and Jupiter offer more specialized choices as your collection grows.
How Weapon Amplification Works
Weapon amplification builds on the Outpost and Research Station introduced in Frozen Trail. To prepare a weapon for amplification, establish your Outpost, upgrade both the Gunsmith and Research Station to Level 4, and upgrade the weapon itself to Level IV.
You will then need an Amplification Module that matches the weapon’s rarity. Research projects and additional materials open access to individual upgrades.
| Weapon rarity | Amplification Module |
|---|---|
| Common | Mk. I |
| Uncommon | Mk. II |
| Rare | Mk. III |
| Epic | Mk. IV |
| Legendary | Mk. V |
Amplifications can change firing behavior, magazine capacity or performance against specific ARC targets. Review the connected nodes before investing, as a choice on one branch can affect which other upgrades remain available.
Best Amplifications by Playstyle
| Weapon | Upgrade | Good choice for |
|---|---|---|
| Rattler | Drum Mag | Sustained automatic fire |
| Il Toro | Slug Rounds | Close-range shots against armored ARC |
| Osprey | Anti-Weak Point | Precision damage against exposed ARC components |
| Bettina | Semi-Auto and X-Rounds | Controlled fire against ARC armor |
| Jupiter | Ergonomic Bolt | Long-range follow-up shots |
This order favors accessible weapons early, followed by more specialized builds. Your own priority should depend on the firearms and materials you already have.
Rattler Drum Mag: Sustained Automatic Fire
The Common Rattler is a useful starting point if you want more time on target before reloading. Its Drum Mag adds 40 rounds to magazine capacity, giving you more opportunities to deal damage during an extended fight.
That extra capacity suits encounters with multiple smaller ARC enemies or prolonged firefights. Spend some time practicing with the upgraded weapon: the drum also increases recoil and dispersion, and the Rattler still loads a few rounds at a time.
Best for: Players who use the Rattler often and want a Common weapon with a larger magazine.
Il Toro Slug Rounds: Focused Close-Range Damage
Slug Rounds change the Il Toro’s shotgun pattern into a single large projectile. The upgrade is appealing when you prefer placing a shot on one armored target at close range.
The Uncommon Il Toro uses an Amplification Module Mk. II, and Slug Rounds are associated with the Solid-Core Casting Tech research project. The single projectile rewards careful aim, so practice placing shots on ARC targets as you get used to the build.
Best for: Close-range players who want a focused anti-ARC shotgun.
Osprey Anti-Weak Point: Precision Against ARC Components
The Rare Osprey fits players who are comfortable aiming at exposed ARC components. Its Anti-Weak Point upgrade increases damage to weak points while reducing damage against armor plating.
Look for clear shots on vulnerable parts rather than firing into armored surfaces. The upgrade is tied to the Targeted Component Trial research project. Ergonomic Bolt is another Osprey option if you want to keep your target in sight between shots.
Best for: Raiders who prefer deliberate shots and can consistently target ARC weak points.
Bettina Semi-Auto and X-Rounds: Controlled Anti-Armor Fire
The Epic Bettina can be built around Semi-Auto and X-Rounds for controlled shots against ARC armor. Review the weapon’s node tree and research requirements before committing materials to the path.
X-Rounds add explosive material to projectiles, increasing damage against ARC armor and adding some base damage. They also affect handling and magazine capacity, so the build favors deliberate fire.
Best for: Players who regularly carry the Bettina and want to focus it on armored machines.
Jupiter Ergonomic Bolt: Keep Targets in Sight
The Legendary Jupiter suits Raiders who favor long-range encounters. Its Ergonomic Bolt upgrade allows you to cycle the weapon while scoped, helping you follow a target between shots. The node is associated with the Action Economy research project.
The Jupiter uses a Mk. V module, making this path a strong choice when long-range shooting is central to your playstyle. If you prefer a Rare precision weapon, the Osprey also has access to Ergonomic Bolt.
Best for: Jupiter players who want a smoother scoped follow-up shot.
Planning Materials and Repairs
Choose one weapon path before gathering supplies. Check its module rarity, research project and node requirements, then reserve materials for the upgrades you intend to use.
When organizing your ARC Raiders Items, keep repair resources in mind alongside research components. Players looking to buy ARC Raiders Items can also plan around a specific loadout, making it easier to identify which materials support their chosen build.
Amplified weapons require Amplified Fragments for repairs. Keep a supply ready for the firearm you take on expeditions most often, especially if you have invested in a specialized set of nodes.
