Before you get freaked out by the scrollfest that lies ahead of you, here is the TL;DR version by Hacklebeast... I do suggest you read the battle report first if you ever intended to do so, if not, do watch this now!
Finally, four lings of PluS make it past the wall and they will be able to annoy the probes for a good amount of time.
EleGant doesn't deem it necessary to abandon his wall and retreat with the zealots and this strategy pays off! He is just barely able to keep his gateway alive.
And the zealot gets out!
The gateway is bound to go down eventually though. And EleGant, upon realising this, sends two of his zealots over to the Zergs base where he manages to force a sunken colony and kill a few extra zerglings.
These four zerglings will, however, soon join the zerglings already waiting in the base.
Confound it!
Believe it or not, only one probe goes down...
EleGant is paying attention to his probes and smartly uses the layout of the minerals to his advantage.
And while teasing the Zerg in his base and keeping his probes alive and mining, the Protoss feels safe enough to throw down a forge. Perhaps a risky move, perhaps his only hope to stay in this game.
Either way, PluS is having none of it.
Except EleGant's zealots manage to come back all the way from the Zerg's base to help defending and although the first cannon is denied, they take out more lings in the process than he could've ever hoped for a cannon to do.
Eventually, PluS abandons his reckless agression and decides to tech to spire on his one base, hoping to catch the Protoss offguard.
EleGant is reading the Zerg's overmind though, and as he's getting his expansion up, he is ready to pump out some corsairs. As you may have noticed, he's also researching +1 air weapons to make his "air fleet" stronger and will be placing down a robotics facility as well.
Soon enough, four mutalisks accompanied by a pair of scourge come in.
PluS unfortuntately splits his scourge and as each hits a different corsair and more cannons are warping in, the mutalisks decide to join the rest of the forces to attempt one final break on the natural.
This is Zerg's last hope. If he can only break this, he has his own base morphing at the natural and might just be able to hold on to this game.
PluS makes his way through despite the effective probe pull! But he can't touch any of the bases anyway. With good enough simcity and cannons at each base, his remaining mutalisks are dealt with by a single corsair.
