Units are an important part of Edgeworld. They're where you'll be gaining most of your levels, and they also can strike your enemies back. Remember, you unlock the barracks at level 1, you unlock the factory at command center level 4, the generals quarters at command center level 6 and last, you get the fleet academy at command center level 11, with barracks at level 1. You can also INSTANTLY unlock a troop for research by winning it, you'll get the troop, and have it instantly be trained to level 1. However, if you do not have the specific building to train that unit, you will not be able to train that unit until you get the building.
