Buildings
What each upgrade actually unlocks — and which buildings you have more than once.
- Values below level 20 for gold mine, iron mine, material factory and training dummy are still missing. A screenshot of the upgrade window at level 16 to 19 backs them.
- The level tables (cost, time, requirements for levels 1–30) are now on the page “Buildings: level tables” — from player sources, not yet verified against the game. One screenshot per upgrade window makes them verified.

The Military Base is the building almost everything depends on. Its level unlocks other buildings and caps how high they can be built. That is why it sits at the top of the upgrade order.

The hospital trap
The hospital has a fixed capacity. Wounded units that no longer fit die permanently. Fight with far more troops than the hospital holds and every defeat costs you units for good — often noticed only in the training bill.
Disabled units go to the hospital first. Everything above that is lost. Upgrading the hospital is not a side issue but insurance.
Resource buildings
A base has 5 each of gold mines, iron mines, food factories and training dummies; at least 2 material factories were visible.
| Building | Output per hour level 16 | Level 17 | Level 20 | Level 21 |
|---|---|---|---|---|
| Food factory | 18,000 | 19,440 | 23,040 | 23,760 |
| Iron mine | — | — | 23,040 | 23,760 |
| Gold mine (coins) | — | — | 14,400 | 15,120 |
| Material factory (hardwood) | — | — | 60 | 63 |
| Training dummy (XP) | — | — | 108,000 | 118,080 |
Storage is full after the max production time (level 20: 10:40 h, level 21: 10:48 h) — after that the building produces nothing. Collect at least twice a day to get the full daily amount (output × 24).
Checked in game and cross-checked against the English community wiki. Where the two differ, it is noted.
