This article will serve as a mission order, tech tree and armory upgrade supplement guide for StarCraft 2: Wings of Liberty. The purpose of this article is to show the order I performed the StarCraft 2 missions in during the writing of my guides and recording of my videos. I found this necessary due to the number of questions I have been receiving about why I have certain tech, or how I’m able to do certain things others cannot, because I unlocked it by playing the missions in a different order. This article will be updated as I continue my progress through the campaign and guide writing, since I have yet to finish the game.
