How to Play Genestealer Cults in Warhammer 40K

6 Minute Read

Today let’s take a look at some basics of how to play and get started with Warhammer 40k 10th Edition Genestealer Cults.

The Genestealer Cults are an insidious Xenos threat that sets rot at the very root of the Imperium. The Cults form from masses of workers, planetary military, Genestealer hybrids, and their Xenos overlords. On the tabletop, Genestealer Cults are a diverse and dynamic faction with a lot to get through.

So below we offer some tips on how to play Genestealer Cults and get started with the army.

Who Are The Genestealer Cults?

Genestealer Cults form if a Genestealer infects members of another species with its genetic code. These resultant changes in the genome of the host cause a fanatical loyalty to the Genestealers.  Because of this, this brood is held together by strong psychic and genetic bonds. They assemble around the original Genestealer, which becomes the Patriarch. Because this community is often hidden behind the facade of a religion or political movement, it is called a Genestealer Cult by the Imperium.

As the cult’s numbers grow the now overgrown original Genestealer is now worshiped as a god. Next, more specialized types of Hybrids are created to serve the Patriarch. These include magiprimusesloci, etc. Afterward the Cult will often recruit from the downtrodden underbelly of society. They characterize themselves as liberators from the brutal yoke of Imperial rule. When mature, a fully developed cult can be huge, numbering in the billions and covering several worlds.

The Cult’s primary concern is their propagation. But over time this transitions to preparing their host world for the coming of a Tyranid Hive Fleet. The Cultists often see this as an anointed holy day of salvation. They will work fanatically to ensure the victim population is ready for consumption. At the chosen hour the Genestealer Cult rises up, unleashing a devastating and well-planned assault. If successful, it can devastate entire planetary systems. So weakened, they are easy pickings for the approaching Tyranid Hive Fleets.

Why Play Genestealer Cults

Genestealer Cults offer an interesting twist on Xenos that is not seen elsewhere. While their allegiance is to the Hivemind (though perhaps unknowingly), the bulk of their forces are more or less human. They are some of the most downtrodden humans the Imperium has to offer. Paradoxically, they are really the most human of the human factions in 40K. Your cultists are closer to everyday people than even the Astra Militarum. However, the parts of the army that are not human, are some of the most powerful!

Strengths of the Army

  • Numerical superiority.
  • Lots of tricky tech. This means myriad deployment options will always keep opponents guessing.
  • A wide variety of effective play styles. Thus you can lean into Brood Brothers, or Hybrids, or Aberrants, or Goliath Trucks, or one of many other options!

Weakness of the Army

  • No world-beater units. This means the Cults have lots of quantity, and plenty of quality, but no “uber” high-point units on par with some other factions.
  • A difficult to play army and low margin for error.

Genestealer Cults Army Rule

  • Cult Ambush– This rule gives your units, especially Battleline, near endless recursion. You will not be tabled.

Genestealer Cults Detachment Rules- Ascension Day

  • RulesThey Came from Below means your units are very effective when they arrive from off board.
  • Enhancements: Most of the GSC enhancements rely on CP manipulation.
  • StratagemsReturn to the Shadows combined with your army rule, makes GSC incredibly hard to get stuck into.

Leaders

Magus


This Leader is a powerful Psyker and Spiritual Leader. In addition, she can join a decent selection of units.

Patriarch


The big honkin’ Purestrain at the heart of a Cult, the Patriarch is a powerful Psyker and does a pretty good slicing and dicing job with his claws. When joined to a unit of Purestrains, they become absolute killing machines thanks to Might From Beyond.

Jackal Alphus


This Biker Leader has great synergy with the Atalan Jackals and with every other unit, due to his Priority Target ability.

Battleline

Acolyte Hybrids


The most alien of the Battleline available to a Genestealer Cult. Furthermore, Hybrids have some strong melee weapon options like the heavy mining tool.

Neophyte Hybrids


The backbone of a basic Genestealer Cult army, Neophytes are cheap and numerous, and can produce CP. Thus one should never be shy about their destruction.

Other Units

Abherrants


Grotesque monstrosities, the Abherrants are some of the best shock troops available to the Cult. These hulking brutes have high damage output, so send them against the hardest targets.

Atalan Jackal


The Atalan Jackal Bikers and Wolfquad are absolutely stellar models. If that isn’t enough, they also pack decent harrying power and amazing mobility to cover ground, and earn game points.

Goliath Rockgrinder


These brutal vehicles got a nice boost, and can really trash enemies. Your opponents quickly learn to beware the Rockgrinder!

Achilles Ridgerunners


The Ridgerunner is an excellent support choice, thank to the Crossfire ability.

Purestrain Genestealers


Able to Deep Strike, Infiltrate, and run and charge thanks to Swift and Deadly– Purestrains shouldn’t have a problem getting in combat, where they thrive.

Hybrid Metamorphs


Metamorphs have high damage and they always get their swings in because of Savage Amalgam.

How to Play Genestealer Cults

Genestealer Cults are not going to overcome any opponent with brute power. If they hope to vanquish their enemies, it must be through tricks, subterfuge, and layering of advantages to the point where they become overwhelming and inevitable. This means getting the most out of both Ambush and Crossfire. Master those rules and you will master this army.
