Starcraft 2 Mass Zerglings into Ultra Build (ZvP)
Home --> Zerg Guide
--> Zerg Build Orders --> Mass Zerglings into
One of the best Zerg build orders to use against Protoss
players involves focusing heavily on upgrades while massing Zerglings. In large enough numbers, these can be
used to deny the Protoss third for an extended period of time while the Zerg works towards Ultralisks.
Before you dismiss this build, keep in mind this build was used successfully in a tournament setting
(WCS 2013 semifinals) by one of the top Zerg players in the world at the time, Jaedong. He was able to beat
First, one of the top Protoss players in the world with this exact build.
The key to using this build successfully is not skimping on the Zerglings. Sure, a handful of Zerglings here and
there can be taken down flawlessly by a Protoss player using Force Field. However, if the Zergling forces get large
enough, you can eventually bleed enemy Sentries dry of Force Field energy. Immortals and Sentries never fair well
against Zerglings and with an upgrade advantage for the Zerg, even Zealots do not stack up well against
Mass Zerglings into Ultralisks Build Order
16/18: Spawning Pool
21/28: Queen x2
22/28: Hatchery (at third)
37/46: Metabolic Boost
47/54: Zerglings x5
57/62: Evolution Chamber x2
60/70: Overlord (sacrifice 1 Overlord here for scouting)
61/70: Melee Ground Weapons & Melee Carapace +1
70/78: Spore Crawler x3 (1 at each base)
73/78: Zerglings x3
91/94: Zerglings x10
This late in the build, things can change depending upon the moves of the opponent. You may have to get out
Zerglings a little earlier to stop a 3 Gate/Stargate play. You will need to make even more Zerglings against a
6-Gate Robo play. You can defend these plays, you just need a lot of Zerglings to stop these attacks.
Once you reach 70 Drones (which should happen by the 10 minute mark), you can cut Drone production and focus
entirely on Zerglings. Use your gas to add on an Infestation Pit and start +2/2 melee ground and carapace upgrades
as soon as +1/1 finishes. As soon as the Infestation Pit finishes, start a Hive. When the gas and minerals become
available, research Pathogen Glands at the Infestation Pit.
The Hive should finish around the same time as +2/2. While the Hive is training, add on 5 Infestors and 5
Queens. Allow these to hide and bank up energy while continue Zergling pressure delays the Protoss third. The
Queens will actually be used on offense to provide light anti-air support and Transfuse for Ultralisks.
Once the Hive finishes, start +3/3 and add on an Ultralisk Cavern. Try to hide the Ultralisk Cavern. Research
Chitinous Plating plus Adrenal Glands and bank up gas. Build about 8 Ultralisks once all your upgrades are 60
seconds from finishing. Finally, add on 3 Vipers with full energy. These will be good for 6 Abducts or Blinding
Cloud and 3 Abducts. Fill up the rest of your supply cap with Zerglings and Queens.
As soon as the Ultralisks spawn and your upgrades finish, move in immediately with your Infestors, Queens,
Zerglings, Vipers and Ultralisks. A good army composition would be 7 Queens (14 supply), 8 Ultralisks (48
supply), 5 Infestors (10 supply), 3 Vipers (9 supply), 80 Zerglings (40 supply). The rest of your supply cap space
would be spent on Drones and Queens at each of your 3 bases.
Strategy for Using the Build
In order to keep disruption of the build to a minimum, you need to use your initial Zerglings to block any
Probes that try to escape the Protoss main. This will prevent the Protoss from hiding proxy Pylons. Once you have
10 Zerglings, you can patrol the map to look for proxy Pylons that might have slipped by. Destroy these Pylons and
the Protoss will not be able to surprise you with an attack. This allows the Zerg to focus fully on macro and Drone
To prevent the Protoss player from taking a third, you will need waves of 30-40 Zerglings. If the first wave
gets shut down by Force Fields, keep what you can alive and send it in again after Force Fields wear off.
Eventually the Sentries will tap out of energy.
To prevent Phoenix harass, this build adds on 1 Spore Crawler in each mineral line plus focuses heavily on Queen
production. This should be all you need to take down Phoenix in the early to mid game. Phoenix do not have the
energy to pick up Zerglings.
Use your Zergling packs to delay the Protoss third as much as possible. Your limiting resource is time here. You
will need to reach the ~15 minute mark before all your upgrades finish and you are ready to move out. You cannot
let the Protoss sit back and max out during this time. You will have plenty of spare minerals with this build, so
regularly make 30-40 Zerglings and send them in whenever you have an opening. Try not to let the Protoss third go
up before the 13:00 mark.
When you actually make your attack, your micro is important. Ultralisks are somewhat clumsy and can be outranged
by building walls and Immortals. Use Blinding cloud on Immortal/Sentry/Stalker packs that are behind ramps. Use
Abduct to pull forward Colossi and burn them down immediately. Use Transfuse to keep Ultralisks alive. Use Fungal
Growth to lock down enemy units and Infested Terrans to take out Void Rays.
