Backpacks

Backpacks increase your inventory space in Marathon, which lets you carry more loot, gear, and supplies out of a run. Many backpacks also include passive effects, which means they can help with things like ammo handling, consumable use, or stealth.

There are over 13 backpacks in Marathon. That pool includes different backpack families and multiple size tiers, from smaller 8-slot options up to a 24-slot prestige backpack.

The current backpack families are Base Packs, Ammo Packs, Med Packs, and Sneak Packs. Base Packs focus on storage, Ammo Packs help with weapon reload and recharge effects, Med Packs improve healing and shield item use, and Sneak Packs add stealth-focused utility

Backpacks come in 8-slot, 16-slot, and 24-slot sizes. In general, larger backpacks offer more carrying space, and higher-end versions can also come with stronger passive perks.

Better backpacks can be found through looting, defeating other players, and securing supply drops. They can also be purchased through the Armory once the right CyberAcme upgrades are unlocked.

CyberAcme is the faction most closely tied to backpack progression right now. Its upgrade tree includes nodes that unlock better backpack tiers for purchase in the Armory.
