Video: Defending against a surprise Zerg rush usually ends with a GG. Defending against a surprise Zerg rush that's already in your base has to end with GG. But not for EJK, who managed to came back from a quite impossible situation.
As EJK spots the Nydus worm (the nasty Zerg transport strain everyone hates) in his base, he immediately walls it in with a bunch of Engineering Bays. Targeting it would be pointless, the Queens would heal it right away. After gaining a few extra seconds with the wall, he had to face multiple rushes of Zerg units coming through the Nydus network, with only a handful of Terran units. But he manages his workers, marines, tanks and medivacs (these two can be pretty deadly together) creatively and with perfect micro.
