Factory

A factory is a terran production structure.

Overview
The factory is an automated terran structure which acts as the primary production center for vehicles, structures, and ammunition.

The factory maintains first-class housing for the elite crews of tanks, walkers and the other mechanical units it produces. The factory walls are made of reinforced neosteel, making the structure one of the most survivable in any terran base. The factory contains heavily reinforced fuel supply reservoirs, as well as interior construction cranes to aid in the lifting and assembly of machinery, and ventral thrusters allowing it to liftoff.

StarCraft
In StarCraft, the factory is used to construct s, s and s. It also has an optional machine shop upgrade to enhance vehicles' offensive weapons and speed.

StarCraft II
In StarCraft II, the factory is compatible with the tech lab and reactor, albeit not both simultaneously.

One additional attribute is that it is required to produce nuclear missiles at the ghost academy.

Development
The balance between team color and metal was the focus of factory development in StarCraft II. During development, artist Phill Gonzales hid posters of "fat chicks" on the back wall of the factory. However, they were spotted during a Q&A session and he was forced to remove them.

As of April 2012, Blizzard was experimenting with a wide range of new terran units for Heart of the Swarm. Many of these originated from the factory, the structure being a "little light" on its unit options.

Heroes of the Storm
Factories appear in the background of the map Braxis Holdout in Heroes of the Storm. After the first zerg wave, they become infested factories.
