- "The Storage Vault allows you to store 2000 of each resource. And through the miracle of modern technology, all that loading and unloading of crates and barrels can be done with only 4 workers! Better still, most of the building is underground, leaving you more room on the surface. The Storage Vault is so underground you probably haven't heard of it."
- — In-game Description
The Storage Vault (changed from Underground Warehouse in the 1.2 Patch) is much smaller than a Small Warehouse, and can store a considerable amount of resources at the cost of 105 . It requires few workers to run, and among resource-storage buildings is second only to the High Capacity Vault in its holding capacity. These facts can make it a great purchase if you have the required Nanopods.
