Dunno if anyone is watching the streams but the Helion harass
on this one is amazing.
He quick tech'd to Helions and snuck one past the toss' approaching attack which the marines back at his base defended and picked off 3 probes. He then dropped another 3 Helions and got like 50% of the probes.
A few moments later he used those same 3 Helions and drop ship, dropped the Helions on one side, showed a drop on the other luring the guys units there and then moved the dropship down forcing the guy to chase it, all the while backdooring the now vulnerable probes.
He's now playing one of the Blizzard community mods.
