Axemen Unit & Copper Strategic Resource
This mods turns the existing Copper bonus resource into a strategic resource. It also adds the Axemen unit, which has +5 combat strenght versus melee units. It has a vulnerability of -10 combat strenght versus light and heavy cavalry. The Axemen requires Copper to be built.
When playing with Gathering Storm, the Axemen require 1 copper initially to be build. After that an upkeep of 1 copper per turn.
It also changes the upgrade path of the Warrior to the Axemen. Axemen upgrade to Musketmen. They provide an alternative way besides Swordsmen. This means there is no unit that upgrades to Swordsmen anymore.
