So, you want to get into Warhammer 40K but don’t know where to begin. The number of factions, rules, and models can feel overwhelming. That’s why we’ve put together this guide on the best starter armies for 2025, giving you a clear idea of where to start and what to expect.
Choosing your first army should be fun, not stressful. By looking at model ranges, lore, and playstyle, you’ll find the faction that matches your style. This article will help you make that choice with confidence.
Space Marines (Imperial and Chaos)
When it comes to Warhammer 40K, there’s no more iconic faction than the Space Marines. Both loyalist and Chaos versions are popular worldwide. Their bulky armor, legendary heroes, and rich lore make them the perfect entry point.
No other army has as much variety. You’ll find melee-focused chapters, shooty legions, fast bike units, daemon-infused warriors, and massive tanks. The only limit is your creativity when building lists.
Space Marines also benefit from availability. Games Workshop pushes them as the flagship army, so you’ll rarely struggle to find kits online or in stores. On top of that, they’re consistently competitive in the rules, making them a safe bet for beginners.
Reasons to start Space Marines:
- Widest model range
- Endless lore and novels
- Always supported in rules and updates
- Easy to find in local shops
Necrons
If you like the idea of robot skeletons and ancient alien tech, Necrons are a fantastic choice. Their lore is filled with enslaved star gods, eerie machines, and apocalyptic destruction.
In terms of rules, Necrons are one of the most consistently strong armies in 10th Edition. Unlike other factions that swing between good and bad, Necrons have stayed competitive all through the edition.
They don’t have as much melee variety, but the shooting options are powerful. From flying saucers with devastating weapons to towering scythe-wielding monsters, Necrons deliver on both cool factor and table power.
Reasons to start Necrons:
- Competitive rules across editions
- Unique alien aesthetic
- Affordable kits compared to some factions
- Core part of the 40K storyline
Adeptus Custodes
Want a smaller, cheaper army to collect? Adeptus Custodes might be your perfect start. These warriors are the Emperor’s personal guard, stronger and tougher than even Space Marines.
Custodes armies require fewer models. Because of their elite nature, you can complete a force with a handful of units, making them one of the most budget-friendly ways to begin Warhammer 40K. They’re also easier to paint and assemble since you’ll have fewer figures.
Their rules emphasize durability and elite power, so you’ll feel the strength of each model on the table.
Reasons to start Custodes:
- Fewer models needed
- Elite, powerful units
- Lower cost to enter the hobby
- Iconic role in Imperial lore
Orks
If you want your army to feel loud, chaotic, and fun, Orks are for you. Their lore is full of humor, wild antics, and brutal energy.
Orks play as a horde army. They favor melee combat and overwhelming numbers, but you can also bring ramshackle tanks, giant walkers, and even some heavy guns. What makes Orks unique is their freedom for creativity. Many players customize their Ork vehicles and infantry with scratch-built bits, reflecting the faction’s belief that “if it looks like it works, it does.”
On the table, Orks thrive by swarming enemies. They’re not subtle, but they’re always entertaining to play and face.
Reasons to start Orks:
- Fun, chaotic faction personality
- High freedom for conversions and hobbying
- Horde playstyle with strong melee focus
- Plenty of room for creativity
Astra Militarum (Imperial Guard)
If you prefer the underdog story, Astra Militarum may be the right pick. These are regular humans fighting against impossible odds. Their lore is grounded, grim, and easy to relate to.
The Astra Militarum appeals to players who enjoy historical modeling. Many units draw inspiration from World War II armies. Expect gas masks, trench coats, Tiger Tank lookalikes, and massive artillery.
On the tabletop, Astra Militarum excels in tanks, artillery, and combined arms. They may not be as durable as other factions, but their numbers and heavy firepower make up for it.
Reasons to start Astra Militarum:
- Relatable “human” faction
- Strong WW2-inspired aesthetic
- Tanks, artillery, and massed infantry
- One of the most grounded armies in 40K
How to Choose the Right Army
The best Warhammer 40K starter army depends on what excites you most. If you want flexibility and lore, start with Space Marines. If you want ancient aliens, go Necrons. For an elite force, Custodes offer a low-model count option. Orks bring fun and chaos, while Astra Militarum appeal to players who love tanks and human grit.
No matter which you choose, the most important part is that you enjoy painting, playing, and building your army.
