How to Expand the Depot
Expand by Unlocking Depot Node

The Depot’s capacity increases when you unlock the Depot Node. Completing the 'Depot Node I' mission and unlocking the Depot Node raises your depot limit by 3,000, allowing you to store more items.
Each Item Has Its Own Depot Limit

The Depot capacity limit defines the maximum quantity allowed for each individual item type, not the total number of items stored. You can collect and store items up to the limit for each item type independently.
Further Expand via Depot Node Upgrade

By Upgrading the Depot Node, you can expand the depot capacity according to the Depot Node's level. To upgrade a Depot Node, you will need Stock Bills, which can be obtained from sources like 'Outpost Management' in Regional Development.
