Marathon features a Vault in which players can store their precious loot without the risk of it being lost on a run. To increase space in the Vault, you need to purchase the Expansion upgrade found with the CyberAcme Faction. There are 5 Expansion Levels, and each adds a new set of rows to the Vault.
Below, we’ll share the entire list of Levels, Credits, and Salvage that you need to acquire each Expansion upgrade, along with how many rows it can provide you with, so that you’re always holding space for precious loot on your next extraction.
How to Increase Vault Space in Marathon
Players can increase Vault Space through the “Expansion” Upgrade with CyberAcme’s Faction, which is the first Faction you unlock in Marathon.
