ECC: REDLINE Weapons & Gunsmith: How Customization Works

ECC: REDLINE features a weapon customization system that lets players modify firearms, save their preferred configurations, and purchase those setups during matches using in-game currency.

Players can swap weapon parts, equip optics, and adjust grips. Prerelease builds also include an extensive attachment system with up to 10 saved weapon presets, purchasable from vending machines across the map.

The system goes beyond changing how a gun looks. Certain attachments affect weapon characteristics, and some components offer additional tuning options.

Here's what has been confirmed so far about ECC: REDLINE's weapons and Gunsmith system ahead of its first PC test.

Weapons in ECC: REDLINE can be modified with different parts to change their characteristics and handling.

According to the game's official Steam description, weapon design emphasizes ballistics, recoil, reload timing, and handling. Players can replace components and adjust their firearms rather than relying entirely on their default configurations.

The prerelease customization system includes several attachment categories:

• Barrels: Replaceable weapon components, with additional tuning possibilities reported in developer coverage.

• Grips: Customization options that contribute to different weapon configurations.

• Stocks: Alternative components available through the modification system.

• Optics: Sights that can be mounted on compatible firearms.

• Tactical accessories: Equipment including flashlights and laser attachments.

Attachment choices differ in appearance and numerical properties.

The exact effects of individual components have not all been documented publicly. While the system allows meaningful changes to a weapon's configuration, there is not yet enough verified data to recommend specific attachments for every gun.

One of the more detailed aspects of ECC: REDLINE's Gunsmith system is the ability to adjust certain attachment parameters individually.

Attachment tuning can modify characteristics such as a part's length and weight.

These adjustments can influence several weapon properties, including range, movement speed, damage falloff, and stability.

This creates another layer of customization beyond selecting a barrel, grip, or stock. Two configurations using the same firearm may have different handling characteristics depending on how their components are adjusted.

The available reporting does not establish the exact adjustment ranges, numerical modifiers, or restrictions for every part. Those details will need to be checked against a playable build.

The prerelease version also includes an AI-assisted weapon configuration feature.

The interface displays an AI option intended to help players configure their firearms, potentially making the attachment system easier to navigate.

The precise functionality remains unclear. The available demonstration does not establish how the AI chooses attachments, whether it can tune every adjustable parameter, or what criteria it uses to recommend a configuration.

For now, AI-assisted setup is a documented feature of the preview build, not evidence that the game can automatically produce an optimal loadout.

ECC: REDLINE connects its weapon customization system to its in-match economy.

Instead of depending entirely on weapons found while looting, players can prepare configurations before entering a match and obtain them later using currency earned during gameplay.

The prerelease purchase process works as follows:

1. Create a weapon configuration before the match. Choose a firearm, modify its attachments, and save the setup. The preview build supported up to 10 saved configurations.

2. Earn currency during the match. Players can collect currency from loot locations, complete bounties, and obtain resources from defeated enemies.

3. Purchase a saved configuration from a vending machine. Once enough currency has been collected, players can visit a vending machine and buy one of their prepared weapon setups.

The currency is called 赛事币 in Chinese-language prerelease material. NetEase's English Steam description refers more generally to in-match credits.

Buying a customized firearm requires a substantial amount of currency, although exact prices remain unconfirmed.

That creates a choice between spending credits on a preferred weapon or saving them for other equipment. Reconnaissance devices and airstrike tools were among the alternative purchases described in the same preview.

It also gives players a way to move beyond whatever weapons they happened to find after landing. A prepared configuration can be purchased later in the match, provided the player has enough credits and access to a vending machine.

The MP5 is one of the firearms specifically identified in ECC: REDLINE's early prerelease information.

Attachment choices can produce different configurations from the same base weapon.

Two possible approaches are:

• Close-range configuration: An MP5 modified with an emphasis on hipfire and nearby engagements.

• More versatile configuration: An alternative setup intended to make the weapon usable across a broader range of encounters, including medium-range fights.

These are examples from prerelease reporting, not verified recommendations for the strongest MP5 builds.

The complete attachment combinations, exact damage values, recoil measurements, and other performance figures for those configurations have not been established in the available details.

What the example does confirm is that ECC: REDLINE's customization system is intended to support different weapon configurations without requiring players to switch to an entirely different firearm.

The MP5 has been directly identified in prerelease information. Prerelease information also refers to bolt-action sniper rifles and marksman rifles as weapon options, although it does not establish a complete roster of specific models.

NetEase has not yet provided a comprehensive English weapon database with verified statistics for every firearm and attachment.

Several details still need confirmation:

• The complete weapon roster and official English weapon names.

• Attachment names, compatibility, and numerical modifiers.

• Weapon damage, fire rates, recoil values, and effective ranges.

• The full extent of attachment tuning.

• Weapon preset limits and purchase costs in the public test build.

There is also no sufficiently detailed, comparable performance dataset to identify the best weapons or most effective loadouts across the roster.

ECC: REDLINE's first limited PC test is scheduled for October 15, 2026. The weapon systems described here come from official information and prerelease prerelease information, so individual mechanics and values may change before release.

For now, the clearest picture is of a Gunsmith system built around attachment customization, finer weapon tuning, saved configurations, and an in-match economy that allows players to purchase their preferred setups.
