1. Four Launch Armies: Side-by-Side Comparison
Selecting a faction changes buildings, economy, commanders, units, and battlefield mechanics. The roster and faction identities below are developer-confirmed; difficulty and mobility labels are editorial guidance based on current official descriptions, not launch balance data.
| Faction Name | Difficulty Rating | Mobility Score | Core Faction Identity | Best Fit Player Profile |
|---|---|---|---|---|
| Space Marines | ⭐ Low (Beginner Friendly) | ⭐⭐ Mid (Drop-Pod Support) | Elite durable squads, flexible commanders | Players who prefer disciplined, low-attrition tactical play |
| Orks | ⭐⭐ Mid (Horde Management) | ⭐⭐⭐ High (Waaagh! Charges) | Mass numbers, ramshackle tech, aggressive rushes | Players who enjoy swarm tactics, constant pressure & aggression |
| Necrons | ⭐⭐⭐ High (Macro Tech Tree) | ⭐ Low (Methodical Push) | Reanimation protocols, immortal war engines | Players who favor defensive scaling & crushing late-game war engines |
| Adeptus Mechanicus | ⭐⭐⭐ High (Network Micro) | ⭐⭐ Mid (Linked Nodes) | Noosphere building links, turret overcharges | Players who love base building synergy & defensive choke-points |
The difficulty and mobility labels are editorial assessments with medium confidence. They are derived from the official faction previews and multiplayer AMA, not from a playable review build. Exact balance, economy efficiency, and matchup strength can change before and after launch.
Choose Space Marines for elite squad preservation
Space Marines field expensive, powerful squads and are expected to win many equal early engagements. Their structures can deploy from orbit anywhere within vision, with longer deployment times farther from headquarters and a visible warning for opponents. Fortifications, Reserves, and the Thunderhawk Relay help compensate for an elite army that cannot occupy every part of a large map.
They are our best beginner recommendation because KING Art Games calls their building progression the most straightforward. Beginner-friendly does not mean mechanically shallow: upgrades, veterancy, retreat timing, on-field reinforcement, and the choice between Blood Ravens and Dark Angels create meaningful decisions. Read the full Space Marines faction guide.
Choose Orks for numbers and forward pressure
Orks combine relatively inexpensive units and buildings with a Waaagh! meter charged by fielding more Orks and killing enemies. Almost any Ork infantry can construct structures; those structures are armed and can bring production closer to contested ground. Orks can also construct their own cover.
This makes them attractive to players who prefer initiative over perfect efficiency. The main risk is overextension: forward infrastructure is relatively easy to destroy, and replacing models can consume the same economy needed for technology. Our Orks guide explains the confirmed units, Gorgutz, Guzcutta, and Waaagh! framework.
Choose Necrons for resilience and territorial snowballing
Necrons expand a Power Matrix from their Tomb Citadel. Many structures require this field, a larger Matrix produces Dominion, and friendly units on it heal faster and become tougher. Resurrection Galleries can return a selected fallen unit type for free, although cooldowns and limitations remain unpublished.
The faction is deliberately slow, but Tomb Pylons, Translocation Science, and the Monolith provide later mobility. Choose Necrons if you enjoy establishing favorable territory and forcing opponents to dismantle a growing system. See the updated Necrons guide for confirmed teleportation and unit roles.
Choose Adeptus Mechanicus for connected infrastructure
The Adeptus Mechanicus link buildings to headquarters through a Noosphere Network. Adding connected structures increases network level, unlocks stronger technology, and benefits production and units within its influence. Auger Vision provides imperfect intelligence under fog of war, while the Void Shield changes ranged firing lines without preventing enemies from walking through it.
This is the strongest fit for players who enjoy base topology, information tools, ranged combined arms, and protecting critical connections. The same dependencies create a higher expected learning curve. The Adeptus Mechanicus guide separates confirmed mechanics from unsupported build orders.
How to choose without a pre-launch tier list
- Choose the economy you want to manage: elite preservation, aggressive expansion, Matrix snowball, or connected Noosphere.
- Choose the map-control style: selective rapid response, forward pressure, fortified territory, or network reach.
- Choose the acceptable complexity: Space Marines appear clearest to start, while AdMech adds more infrastructure dependencies.
- Ignore “best faction” claims without a version and test method: no reliable competitive sample exists before release.
- Reassess after launch: maps, mode, Commander selection, and balance patches may matter more than a general ranking.
2. Summary & Army Recommendation Verdict
Which Army Should You Pick First?
- Pick Space Marines if: You are new to RTS games or want strong, durable units that are easy to manage.
- Pick Orks if: You love non-stop aggression and swarming enemy resource points from minute one.
- Pick Necrons if: You enjoy slow, unstoppable late-game technological pushes.
- Pick Adeptus Mechanicus if: You enjoy intricate base building and networked defense systems.
Final recommendation: start with Space Marines if you are uncertain, choose Orks for relentless initiative, choose Necrons for methodical scaling, and choose Adeptus Mechanicus when base-network planning is the main appeal. These recommendations describe learning style and faction fantasy, not expected win rate.
