Campaign version[]
Because the four original campaigns have not been rebalanced since the release of the game, Iron Undermesh has the following main differences in these campaigns:
- It is researched at the Arsenal instead of the Blacksmith. Because the Arsenal is a Castle Age building, Iron Undermesh cannot be researched until the Castle Age despite being a Feudal Age technology.
- The Mongols have access to an improved version of Iron Undermesh, which costs 350 stone extra and increases ranged armor by an additional +1 (+2 total).
