In order to use the Starcraft 2 baneling rush strategy effectively enough to subdue an opponent, your timing has to be very precise! This means you cannot be slowed down by a bad 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.
