Bunker Rush / Aggression

The 2Barracks Bunker Aggresion is annoyingly much harder for a Zerg player to defend against than for the Terran player to set up. Since we are Hatch first Zergs we need to pull our Drones. You need to either kill all the constructing SCVs or intercept every Marine, making for Bunkers without any firepower. Try to not lose any Drones, rather pull too many than too little. The Terran may transition into an early Command Center while still harrassing with reactored Hellions. But what you may be pretty sure of is that he will not have much Vespene Gas.

How to precede as Zerg after holding of a Bunker Aggression?

Well, since he will not have Tanks or Banshees as soon as with an standart Gas focused opening Roaches are a good choice as they shut down an early Command Center from landing and keeps you safe from any Hellions. Controlling the Hellions, you now have the map control again, so take the Xel'Naga Watchtowers, take your third and spread your Creep. Also get the standart Baneling/Zergling/Mutalisk mix with Melee Attack, Ground Carapace and Flyer Attack upgrades.
