Space Link

Overview
The Space Link is a building that carries over from the original game, The Conquerors. It is the second most-expensive production building in the game, as well as the third most expensive building overall, costing $440. It requires a ten minute research time for 100$ (if one research center is used from the beginning).

However, the unit production from a Space Link does not require the Space Link research. This means that if an ally has placed down a Space Link, you can start producing units from it without needing to research anything (as long as you have a Command Center).

Usage
The Space Link is used to create Motherships and Space Fighters, two of the strongest air units in the game. Even though the Space Link has low health compared to other buildings, it can be used to create Motherships, which are able to produce Space Fighters. This can be very useful if an enemy takes down your Space Link and you are left, only with a Mothership.
