About Marathon Weapon Mods

Marathon Weapon Mods

Weapon mods in Marathon let you tweak how each gun performs. There are 7 mod slot types: Barrel, Chip, Generator, Grip, Magazine, Optic, and Shield. Each mod changes specific weapon stats, and not every mod works with every weapon, so the available options depend on the gun you're building. There are currently 138 mods in the game, and each one lists which weapons it's compatible with and what stats it changes. You can plan your full mod setup using our Complete Loadout Builder to see how different combinations affect your weapon before committing in-game.

Frequently Asked Questions

What are weapon mods in Marathon?

Weapon mods are attachments that change your gun's stats. Each mod belongs to a specific slot type (Barrel, Chip, Generator, Grip, Magazine, Optic, or Shield) and modifies things like damage, range, recoil, or reload speed depending on the mod.

Can every weapon use every mod?

No. Each mod is only compatible with certain weapons. When you click on a mod, you can see which weapons it works with. The number of compatible weapons varies per mod.

How many weapon mod types are there?

There are 7 mod slot types in Marathon: Barrel, Chip, Generator, Grip, Magazine, Optic, and Shield. Each weapon has its own set of available slots, and you fill them with compatible mods to customize your build.

How does MarathonDB get its mod data?

We test every mod in-game and record the stats by hand. We don't rely on a Bungie API, everything here was manually verified.

Can I submit corrections or missing mods?
