I just watched this replay and I don't know how the Zerg could break that Terran fortress. He tried everything - nydus worms, mutas, brood lords, ultras, banelings, and Terran just created indestructible Planetary Fortresses - Turrets - Sensor Towers
wall, plus massed a large army of MMM + Vikings.
Does anybody have any ideas how to win against incredibly-fortified Terran (as Zerg), who isn't a noob? And Terran wasn't just on 21-32 expos, he had half of the map.
