Blizzard have released the second of their Starcraft II "Battle Reports", which feature developers giving a play-by-play as two players duke it out in the upcoming strategy title.

This episode shows the Zerg facing off against the Terrans, and...well, it's over 20 minutes of real Starcraft II gameplay footage. Get comfortable.
