UPDATE: Made some changes for launch day. Yes, "Star Craft 2" comes out today, so the only reason you should be reading this is if you're sitting at work, dying to play.
On the eve of the launch of "StarCraft 2," we realize there's a lot of information to digest. For example, ever wonder how many Zerglings or Templars it takes to make a Baneling or an Archon? Ever ponder what an Ultralisk will cost you or how many more minerals a MULE can collect? Wonder, ponder, and consider no more. Below is your "StarCraft 2" unit guide, complete with information on each unit's upgrades, costs, required buildings, and a short summary on what they're all about.
