The Den's confirmed upgrade rules are about campaign infrastructure: construction takes at least one Cycle, uses an available Build Slot, and can improve the company through recruitment, weapon, Utility, and capacity options. The official material does not publish a complete upgrade tree, cost table, or prerequisite map.

Construction rules
| Confirmed rule | What it means |
|---|---|
| Construction time | An upgrade takes at least 1 Cycle to construct. |
| Build Slots | Construction requires an available Build Slot. |
| More Build Slots | Additional Build Slots unlock over time. |
| Company impact | Upgrades can improve Den infrastructure and squad effectiveness. |
These rules do not establish every upgrade's cost, level, prerequisite, or exact unlock Cycle. Official sources do not currently publish an exact value for those unlisted fields.
