Starcraft 2 Baneling Rush Build Order
If the Starcraft 2 baneling rush build order you decide to use gets the wrong upgrades at the wrong time, it will usually result in the timing of your attack being too late or not strong enough to do any real damage.
Here is the best Starcraft 2 baneling rush build order I've been able to find thus far: 10/10 -> Build Drones 12/10 -> Double Extractor Trick to build 2 more Drones 12/10 -> Build first Overlord 14/18 -> Build an Extractor with 3 drones mining 15/18 -> Build a Spawning Pool 15/26 -> Build a Roach Warren 15/26 -> Build a Queen 17/26 -> Build a Zergling 17/26 -> Build a Zergling 19/26 -> Build a Baneling Nest 19/26 -> Build another Overlord 19 - 28 -> Build Roaches to support Banelings The banelings need to go in first in order to break any kind of wall your opponent might be locked up behind.
This means sending them in mass numbers to make sure that your baneling rush doesn't get deflected quickly.
Have a few roaches ready to support the attack as soon as it hits your opponent's base.
The roaches are very important simply because you cannot expect success relying on one unit alone such as the baneling.
The baneling's damage is great but also limited since it only has one suicide attack.
Take advantage of this suicide attack by using it to take out large groups of infantry, then immediately move into roaches to kill off the remaining couple of units and destroy your opponent's buildings.
