In the Starcraft 2 Zerg vs Protoss matchup, it all boils down to a fight between flesh and technology. Each race in the game has its own strengths and weaknesses.
What the Zerg do best of all the races of the game is numbers, sheer strength of numbers. When you couple that with the Zerg’s ability to produce those numbers extremely fast, that’s when you find yourself in a game-winning situation.
The ability to swarm your opponents with countless numbers of Zerglings has been a time honored tradition of Zerg players ever since the original game, but the Protoss in SC2 have a new unit that puts a damper on that particular tactic.
Dealing with Sentries
Sentries are very cheap units that the Protoss can produce rather quickly. They work best as a support unit by protecting units around them with their shielding abilities. The reason why Sentries are so powerful against a Zergling rush is because of their Force Field ability. This is used to a great effect by experienced Protoss players who break up a Zergling swarm and keep it at bay. This tactic allows their fewer but considerably more powerful units to deal with small numbers of Zerglings.
The best way of eliminating this advantage is to simply not make that many Zerglings and instead build yourself a mixed army of Lings and Roaches or Hydralisks. The ranged damage from the latter units will prove to be too much for the Sentries to handle in a very short amount of time.
Of course whether to go for Roaches or for Hydralisks should be an important decision, and it should be made once you know what your opponent is building besides Sentries.
Roaches are a great choice because they are cheap and extremely effective against ground units – we will have a special Roach build later in the article. However, they are an Armored unit which means that Stalkers and especially Immortals will do massive damage against them. Hydralisks on the other hand, are not Armored, and they can attack air units as well, but they are more expensive and will take longer to tech up to.
Basically having a mixed army of Lings and Roaches should provide good results, as long as you take out the Sentries first with your Roaches so that your Lings can start wreaking havoc.
The 5 Roach Rush
This build is similar to the one you can use against a Terran player but with a few discrete changes.
You start off with a basic build order till you get your first pair of Zerglings at fifteen supply. That’s when you start building a Queen and two more Drones.
Secrecy is crucial to the success of this tactic. This means that your opponent must not be aware that you are planning on making Roaches this quickly. If he sees the Roach Warren then he’ll be able to go for Stalkers or Immortals. This means that you need to keep his scouting Probe at bay with your Zerglings and only start creating a Roach Warren when you’re sure he can’t see it.
The Queen’s Spawn Larva ability is also very important to the success of this tactic. Once you have your five Roaches ready you should also be capable of creating a Hatchery at your natural expansion point – you need to do this in order to ensure that even if the rush fails, you’re in a solid economic position to continue the game. While this is going on you’ll want to continue spawning some Zerglings and evolving Metabolic Boost. Reinforcing your Roaches is very important.
Once you reach the opponent’s base your priorities should be any ranged units he might have and of course, Sentries. In order to let your Lings into the base without being harassed by Zealots you should block their path with your Roaches.
