← ALL GUIDESWhat are the best mods in Marathon?
Top-tier mods are Superior and Prestige rarity — check our Meta Mods showcase for current picks. Stack damage, handling, and stability mods on your primary weapon, and recovery/resistance mods on your shell. Faction-locked mods like those from Traxus and Arachne are often build-defining.
How do mod slots work in Marathon?
Each shell and weapon has a fixed number of mod slots. Weapons typically have 3-4 mod slots depending on rarity, while shells have separate slots for core, implant, and mod. Higher rarities unlock more slots and stronger mod effects.
Do mods stack in Marathon?
Most mods stack additively — two 10% damage mods give 20% total. Some mods have diminishing returns or conditional stacking. Our mod guides cover stacking rules for every mod type.
