Upgrades

In Age of Fear, there are plenty of upgrades that can be obtained for your troops in shops. They are obtained by expending a set amount of experience and sometimes gold. Some also require other upgrades to be obtained. Sometimes they replace previous upgrades, which I will hereafter refer to as "Chain Upgrades"
