Some fans with low internet speed connections may have issues trying to download any of both Gameplay videos of Starcraft II.  One is 459MB, while the smaller size video is above 200MB.

Fear not.  I have transcribed everything the developer narrates within the video.  You can now read what the video narrates. Discover more details of each Protoss unit and their abilities.  Specially the Mothership; and which units are needed to counter them.

NOTE: Screenshots now Available.
