Starcraft 2: Wings of Liberty Terran Buildings: Tech Lab

This StarCraft 2 unit guide will cover the Terran Tech Lab add-on building. The Tech Lab is an add-on constructed by either the Barracks, Factory or Starport allowing these production facilities to produce more units, and in melee mode, allows the research of certain upgrades at the Tech Lab depending on what primary structure it is attached to. The Tech Lab is a new add-on in StarCraft 2: Wings of Liberty meant to replace the Academy, Machine Shop and Control Tower from the original StarCraft.

The Tech Lab is first used in the StarCraft 2: Wings of Liberty campaign mission 'The Outlaws'
