Game Guide by Navid Kabbo on Oct 08, 2026

Gears of War: E-Day introduces a weapon customization system that allows players to modify their firearms with different attachments and upgrades. Whether you're improving the accuracy of your Lancer, increasing ammunition capacity, or changing how a weapon performs during Active Reload, Weapon Mods provide additional flexibility during combat.

Gears of War E-Day Weapons

Unlike previous Gears of War titles, E-Day lets players customize individual weapons to better suit their playstyle. However, these upgrades aren't immediately available, and some require exploration, progression, or Weapon Parts before they can be equipped.

This guide covers all Weapon Mod types in Gears of War: E-Day, including how to unlock them, what each category does, and how to customize your weapons in Campaign and Horde Siege.

How Weapon Mods Work in Gears of War: E-Day

Weapon Mods are attachments that change different aspects of a weapon's performance. Depending on the modification, you can improve handling, increase ammunition capacity, enhance accuracy, or change how a weapon functions.

Weapon Mods are available in Campaign and Horde Siege, but they aren't used in Versus multiplayer.

The main Weapon Mod categories include:

Barrel Mods
Stock Mods
Magazine Mods
Scope Mods
Body Mods
Fire Mode Mods
Perfect Reload Mods
Miscellaneous Mods

Each weapon has its own selection of compatible modifications. This means you cannot necessarily equip the same attachment on every firearm.

All Weapon Mod Types

Barrel Mods

Barrel Mods change a weapon's firing characteristics, with certain attachments improving accuracy, damage, or other aspects of performance.

These upgrades are particularly useful for weapons that you regularly use during medium-range engagements.

If you're struggling to maintain consistent damage with an assault rifle, checking its available Barrel Mods is a good starting point.

Stock Mods

Stock Mods primarily focus on improving weapon handling and stability.

Gears of War E-Day Stock Mods

They can make weapons easier to control, especially when firing repeatedly or dealing with recoil during longer engagements.

Players who prefer assault rifles and sustained gunfire should consider these modifications when building their loadouts.

Magazine Mods

Magazine Mods affect ammunition-related characteristics, including magazine capacity and other reload-related benefits.

Having more ammunition available before reloading can be particularly useful when fighting groups of Locust enemies.

These upgrades are worth considering for weapons that frequently run out of ammunition during extended firefights.

Scope Mods

Scope Mods modify a weapon's aiming capabilities.

Gears of War E-Day Scope Mods

Depending on the attachment, they can improve visibility, targeting, or precision when engaging enemies at longer distances.

Precision weapons such as the Longshot and Breechshot can benefit from appropriate scope modifications, especially when you're regularly fighting enemies across large areas.

Body Mods

Body Mods alter additional weapon characteristics that aren't necessarily tied to the barrel, magazine, or scope.

Their effects vary depending on the weapon, so it's important to check each modification's description before equipping it.

Some Body Mods may complement a particular weapon build better than others.

Fire Mode Mods

Fire Mode Mods are among the more interesting customization options because they can change how a weapon fires.

Rather than simply improving an existing statistic, these modifications may alter firing behavior and create new ways to use a weapon.

They're worth experimenting with if you want a firearm to perform differently from its standard configuration.

Perfect Reload Mods

Perfect Reload Mods enhance the bonuses associated with successfully performing a Perfect Active Reload.

Depending on the weapon, these modifications can provide benefits such as improved damage, increased firing speed, or special ammunition effects.

For example, the Breechshot has Perfect Reload modifications such as Full Metal Jacket, Hardened Ammo, and Springloaded Mag, each providing different benefits.

These upgrades are particularly valuable for players who can consistently perform Perfect Active Reloads.

Miscellaneous Mods

Miscellaneous Mods include specialized modifications that don't fit neatly into the other categories.

Their effects depend on the weapon and can provide unique functionality or additional combat utility.

Because these upgrades vary considerably, check their descriptions carefully before deciding whether they fit your loadout.

How to Unlock Weapon Mods

Weapon Mods can be obtained through different activities depending on the game mode.

Gears of War E-Day Gameplay

In Campaign, players can discover upgrades through exploration, including hidden Hard Cases and rewards associated with optional objectives.

In Horde Siege, Weapon Mods are connected to class progression and Weapon Parts.

To unlock modifications in Horde Siege:

Play Horde Siege and earn class experience.
Level up your class to unlock additional modifications
Earn Weapon Parts through Horde Siege activities.
Successfully extract to retain the Weapon Parts collected during a mission.
Purchase available modifications and equip them through your loadout.

Remember that unlocking a modification through progression doesn't necessarily mean you've purchased it.

How to Equip Weapon Mods

In Campaign, Weapon Mods can be managed at Supply Caches found throughout the chapters.

Once you reach a Supply Cache, access the weapon customization options and select the weapon you want to modify.

Choose an available attachment and equip it in a compatible slot.

In Horde Siege, modifications can be managed through the loadout system after they're unlocked and purchased.

Keep in mind that available mod slots are limited, so you'll need to choose upgrades that complement one another.

Best Weapon Mods to Use

The best Weapon Mods depend on your preferred weapons and how you approach combat.

For a balanced setup, consider the following priorities:

Assault rifles: Stability, magazine capacity, and handling improvements.
Shotguns: Close-range effectiveness and reload-related upgrades.
Sniper rifles: Precision, targeting, and Perfect Reload bonuses.
Heavy weapons: Damage-related upgrades and ammunition efficiency.
Sidearms: Handling improvements and specialized firing modifications.

Rather than focusing entirely on damage, consider whether a modification addresses a weakness you frequently encounter.

A weapon that's easier to control can sometimes be more useful than one that deals slightly more damage.

Final Thoughts

Weapon Mods add another layer of customization to Gears of War: E-Day, allowing players to adjust their favorite firearms for different combat situations.

Whether you're improving your Lancer's stability, upgrading your Gnasher, or experimenting with Perfect Reload effects, the right combination of modifications can make your loadout more effective.

Focus on unlocking upgrades for weapons you regularly use, experiment with different combinations, and take advantage of Campaign exploration and Horde Siege progression to expand your collection.
