Mine Bases
Mine Bases produce significantly more Iron than Resource bases but are limited to 4 per player. They have the highest Iron production rate among all base types, making them valuable for players who rely heavily on Armored and Sea units.
Why Build Mine Bases?
Mine Bases are specialized for high-volume Iron production:
| Comparison | Mine Base (Lv 10) | Iron Resource Base (Lv 10) |
|---|---|---|
| Production | 2,000 Iron/hour | 1,000 Iron/hour |
| Maximum Bases | 4 | 10 (shared with other resource types) |
Mine Bases produce double the Iron of regular Iron Resource Bases at the same level, making them essential for players focused on Armored or Sea unit strategies.
Base Construction Costs
Building Mine Bases requires WWO-Influence, with costs increasing for each additional mine:
| Number of Mine Bases | Construction Cost (WWO) |
|---|---|
| 1 | 8 |
| 2 | 10 |
| 3 | 12 |
| 4 | 14 |
Mine Base Levels
| Base Level | Upgrade Time | XP Gained | Iron Production p/ hour | Upgrade Cost (Brick) |
|---|---|---|---|---|
| 1 | - | - | 875 | - |
| 2 | 2 minutes | 125 | 1,000 | 1,000 |
| 3 | 5 minutes | 156 | 1,125 | 2,000 |

- Navy-focused strategy - If you use Christy, Pomornik, Arleigh Burke, or Akula II units
- Headquarters upgrades - Iron is required for HQ upgrades, so Mine Bases accelerate your progression
