ARC Raiders Amplified Weapons introduce a fifth weapon tier that lets players change how selected firearms perform in combat. Instead of offering only a basic stat increase, amplification unlocks specialized upgrades that can change firing modes, magazine capacity, ammunition effects, and weapon handling. It also increases maximum durability, making it a useful investment for players who want to customize their preferred weapons.
Unlocking this system requires an upgraded Outpost, Level 4 Gunsmith and Research Station facilities, and an Amplification Module that matches the weapon’s original rarity. Since amplification is permanent, understanding the requirements and available upgrade paths before spending rare materials is essential.
Requirements for Unlocking Amplified Weapons
You must unlock the Outpost and expand it to Level 4 before completing the required workshop upgrades. Both the Gunsmith and Research Station need to reach Level 4, while the weapon you want to amplify must already be at Tier IV.
The Gunsmith upgrade requires an Emperor Modulator, along with other crafting materials. The Research Station upgrade requires a Frigate Inductor and additional resources. These items are found through different activities, so plan your raids around the materials you still need.
| Requirement | Key Material or Condition | Purpose |
|---|---|---|
| Outpost Level 4 | 40 Sheet Metal, 3 Laser Levels, 3 Insulation Rolls | Unlocks the required workshop progression. |
| Gunsmith Level 4 | 3 Radial Presses, 3 Magnetic Accelerators, 1 Emperor Modulator | Enables weapon amplification. |
| Research Station Level 4 | 3 Thermal Shakers, 3 ARC Data Modules, 1 Frigate Inductor | Unlocks advanced weapon research. |
| Tier IV weapon | Complete its standard upgrade path | Makes the weapon eligible for amplification. |
| Matching Amplification Module | Mark I through Mark V | Raises the eligible weapon to Tier V. |
The Emperor Modulator comes from the fallen Emperor on Pendola Pass. The Frigate Inductor can be found in breachable containers aboard the ARC Frigate. Both are important progression items, so keep track of them rather than treating every piece of rare loot as interchangeable.
How to Find the Right Amplification Module
Amplification Modules come in five marks. Each mark matches a weapon’s original rarity, so a higher-mark module cannot replace a lower-mark module simply because it seems more valuable.
| Amplification Module | Weapon Rarity |
|---|---|
| Mark I | Common |
| Mark II | Uncommon |
| Mark III | Rare |
| Mark IV | Epic |
| Mark V | Legendary |
The ARC Frigate and the fallen Emperor are the main locations to search for Amplification Modules. On the Frigate, focus on breachable cargo containers and prepare an extraction route before moving into dangerous areas. At the Emperor, bring suitable equipment and the required access item before entering the wreck.
To reach the fallen Emperor, you may need an Emperor Gateway Conduit. Its crafting materials include Conductive, Insulated, and Plated Couplers, which are associated with Emperor Payloads during the Redirection map condition. Collect the required components before making the trip so you can use your raid time efficiently.
How to Amplify a Tier IV Weapon
Once your facilities and weapon meet the requirements, the amplification process is straightforward. However, you should check the weapon and module carefully before confirming because the change cannot be reversed.
- Upgrade your Outpost to Level 4.
- Upgrade both the Gunsmith and Research Station to Level 4.
- Bring your chosen weapon to Tier IV through its normal upgrade path.
- Open the Gunsmith’s Weapon Upgrades section and select the eligible weapon.
- Use the matching Amplification Module to raise the weapon to Tier V.
Amplification consumes the module and fully repairs the weapon during the process. It also permanently integrates the upgrade into the weapon, so choose a firearm you intend to keep using.
What Changes at Tier V
Amplification increases maximum durability and unlocks a dedicated upgrade tree. Many non-legendary weapons gain 70 maximum durability, taking them from 130 to 200. Legendary weapons can receive a larger increase, so check the displayed weapon stats before confirming the upgrade.
The durability increase helps weapons withstand more wear before reaching their minimum condition. Amplification can also change how a gun behaves, depending on the upgrades available for that weapon.
Examples of possible modifications include:
- Firing mode changes: Some upgrades can convert a weapon to full-auto, burst-fire, or semi-auto operation.
- Magazine improvements: Certain paths provide larger magazines for sustained shooting.
- Ammunition changes: Specialized rounds can alter how a weapon performs against ARC enemies or other Raiders.
- Handling and aiming options: Some upgrades add scopes or improve reload performance.
Not every weapon has the same options. Review its upgrade tree to see which changes are available before deciding whether it fits your preferred combat style.
How Amplified Research Works
Reaching Tier V unlocks the weapon’s amplification tree, but some upgrades require separate research at the Level 4 Research Station. Each research project has its own conditions and may require a combat challenge, a specific ARC component, and 5,000 Research Points.
You must complete the relevant task and submit the required resources before the corresponding upgrade becomes available. Unlocking a research project does not necessarily install the modification automatically; you still need to apply the upgrade to your weapon.
Some basic modifications can be accessed without advanced research, while other options sit behind additional requirements or earlier nodes in the upgrade tree. Certain branches also compete with one another, meaning choosing one upgrade can block an alternative path.
Before spending Research Points, inspect the available nodes and decide what you want the weapon to do. A build focused on fighting ARC enemies may benefit from specialized ammunition or weak-point damage, while a weapon intended for Raider encounters may be better suited to a different firing mode or handling upgrade.
How to Repair Amplified Weapons
Amplified weapons use Amplified Fragments for repairs rather than relying entirely on standard weapon repair resources. These fragments can be obtained by recycling spare Amplification Modules or eligible amplified equipment.
Keep some spare resources available if you plan to use an amplified weapon regularly. A powerful build is less useful if you cannot afford to maintain it between raids. Check durability before entering a high-threat area, and consider whether the expected reward justifies bringing your most valuable weapon.
Managing Resources for Weapon Progression
Amplification requires several types of materials, from workshop upgrade components to rare modules and research items. Keeping an inventory plan makes it easier to decide which raids to run and which items to save.
ARC Raiders Items can support your broader progression by helping you keep track of the materials and resources needed for your next upgrade. Prioritize the items required for the Gunsmith, Research Station, and weapon modifications you plan to unlock.
You can also choose to buy ARC Raiders Items when exploring resource options for your progression plans. Match your choices to your current upgrade goals, and make sure you understand which materials are required for amplification, research, and maintenance.
Planning Your Tier Five Build
A strong amplified weapon starts with the right preparation. Reach Outpost Level 4, upgrade the Gunsmith and Research Station, bring your chosen firearm to Tier IV, and obtain the Amplification Module that matches its rarity. Then review its upgrade tree before committing to permanent modifications.
With the right module and research plan, Tier V amplification can give your preferred weapon a new role in combat. Choose upgrades that match your playstyle, keep enough materials for repairs, and focus your resources on weapons you expect to use regularly.
