Mechanicus 2 Factions & Best Units: Necrons vs Adeptus
Mechanicus 2 factions and best units guide: Adeptus Mechanicus vs Necrons, playable campaigns, unit roles, builds, leaders, and first-campaign choice.
Faction Answer
Mechanicus 2 lets players experience both the Adeptus Mechanicus and the Necrons through distinct campaigns. That is the central faction answer. The better first question is not which side wins a tier list, but which resource loop you want to learn first: Cognition for Adeptus Mechanicus or Dominion pressure for Necrons.

Key Facts
Adeptus Mechanicus vs Necrons
The faction question matters because Mechanicus II is built around two sides of the conflict. The Adeptus Mechanicus campaign follows Magos Dominus Faustinius, while the Necron campaign follows Vargard Nefershah. For players, this means the first decision is about perspective, tactical identity, and how much they want to learn at once. Adeptus Mechanicus players should expect Cognition decisions, while Necron players should expect Dominion decisions.
| Faction choice | Best current reading |
|---|---|
| Adeptus Mechanicus | Best first fit for players who want tech-priest flavor, battlefield control, and a more methodical Imperial campaign perspective. |
| Necrons | Best first fit for players who want ancient machine-legion fantasy, awakening tomb-world pressure, and a campaign from the other side of the war. |
| Leagues of Votann | Public preview coverage says the Leagues of Votann appear in the story, but they are not presented as a playable third campaign faction. |
| Resource identity | Adeptus Mechanicus players should expect Cognition decisions; Necron players should expect Dominion decisions. |
| Do not overstate yet | Final best units, optimal army compositions, and hardest-mission counters should match patch version, difficulty, and campaign side. |
Faction Comparison for New Players
The practical choice is not only lore. It changes which resource you learn first, which leader you protect, and whether you want the sequel to feel closer to the original Mechanicus or to start from the new Necron perspective.
| Faction or force | What it means | Best use |
|---|---|---|
| Adeptus Mechanicus | Defined tech-priest leaders, Cognition decisions, specialist protection, and a closer connection to the first game. | Best first if you want the more familiar Imperial campaign. |
| Necrons | Dominion pressure, tomb-world fantasy, durable machine-legion identity, and the biggest new playable perspective. | Best first if the sequel hook is playing the other side. |
| Leagues of Votann | Present in the story and battlefield context according to previews, but not presented as a playable third campaign faction. | Track them as story content, not a campaign choice. |
| Space Marine allies | Preview coverage shows Space Marine allies appearing in battle context. | Do not treat them as a full playable campaign unless official store copy says so. |
Units and Build Guidance
Best-unit questions are useful only when they include the job a unit needs to do. Use the table below to judge units by role, resource stability, leader protection, objective pressure, and whether the same value repeats across missions.
| Unit role | What it solves | How to judge it |
|---|---|---|
| Leader | Mission routing and survival anchor | Keep protected until the mission proves leader exposure is safe. |
| Frontline body | Absorb pressure and hold angles | Judge by durability, cover access, and whether it keeps specialists alive. |
| Ranged specialist | Remove priority threats or trigger safe trades | Avoid exposing it for one large hit if the next enemy turn can punish it. |
| Objective runner | Interact with consoles, marked tiles, or mission triggers | Keep at least one mobile unit free before ending a turn near objectives. |
| Resource enabler | Support Cognition or Dominion flow | Value repeatable resource stability over flashy damage while learning a campaign. |
| Build direction | What it means | When it helps |
|---|---|---|
| Safe first build | Leader protection, cover discipline, one reliable ranged threat, and resource stability. | Best for learning missions without resetting constantly. |
| Aggressive build | More damage and faster objective pressure, but only after you understand turn order and enemy threat ranges. | Use when you can predict the next enemy activation. |
| Control build | Terrain use, objective timing, debuffs, and delaying bad enemy turns. | Best when missions punish direct damage races. |
| Campaign economy build | Upgrades and units chosen around the resource bottleneck you repeatedly feel. | Best after several missions reveal what your faction lacks. |
| Not recommended yet | Copying a final best-build list without knowing patch version, difficulty, or campaign side. | Too easy to follow advice that does not match your run. |
Are the Leagues of Votann Playable?
The safest current answer is no: the confirmed playable campaign structure is Adeptus Mechanicus and Necrons. Public preview coverage says the Leagues of Votann appear in the story, which makes them important for lore and mission context, but current store descriptions do not present them as a third playable campaign faction.
How to Choose a First Campaign
Choose Adeptus Mechanicus first if you want the sequel to feel closer to the tech-priest identity that made the first Mechanicus stand out. Choose Necrons first if the new playable perspective is the reason you are here. Either way, stay with the campaign long enough to learn its economy before judging final difficulty or unit strength.
5-Step Faction Decision
| Step | Do this | Why it matters |
|---|---|---|
| 1. Read the campaign fantasy before the meta | Pick Adeptus Mechanicus for tech-priest Cognition decisions or Necrons for Dominion-based pressure plays. Stay with the side for at least several missions before judging the campaign. | Both factions have distinct resource systems. Learning one side first prevents shallow first impressions and makes later faction comparisons more useful. |
| 2. Judge units by role, not damage screenshots | Evaluate each unit by leader safety, objective interaction, resource contribution, durability, and repeatable mission value before chasing tier-list rankings. | Tier claims depend on patch version, difficulty, and campaign side. Role-based evaluation survives balance updates better than single-number rankings. |
| 3. Track Leagues of Votann as story, not campaign | If preview coverage mentions Votann, treat them as mission context and battlefield flavor. Do not plan a save around a third playable campaign. | Current store copy presents only Adeptus Mechanicus and Necrons as playable campaigns. Votann lore matters, but it does not change the first-campaign choice. |
| 4. Lock in a leader protection habit early | Keep Magos Dominus Faustinius or Vargard Nefershah behind cover, away from open lanes, and supported by mobile units. Spend faction resources defensively when leader exposure is real. | Leader loss is the most common campaign-failure pattern. Defensive resource spending is cheaper than restarting a late-campaign mission. |
| 5. Test Space Marine allies as support, not as army | Use Space Marine allies shown in preview coverage for specific tactical moments. Do not build a save expecting them to replace a primary roster. | Ally appearances in battle context are not the same as a playable roster. Treat them as situational reinforcements, not as a third army identity. |

Frequently Asked Questions
Q: What factions are playable in Mechanicus II?

Q: Who leads the Adeptus Mechanicus campaign?
Steam names Magos Dominus Faustinius as the Adeptus Mechanicus campaign commander.
Q: Who leads the Necron campaign?
Steam names Vargard Nefershah as the Necron campaign commander.
Q: Which faction is best in Mechanicus II?
Adeptus Mechanicus is the safest first pick for players who played Mechanicus 1 — their Cognition resource system and tech-priest gameplay feel familiar, and Magos Dominus Faustinius has clearer starting support. Necrons are the stronger pick if you want the new experience: Dominion pressure rewards aggressive play and Reanimation Protocols provide recovery insurance. Pick Adeptus Mechanicus for a methodical learning curve; pick Necrons for forward-pressure gameplay.
Q: Which Mechanicus II faction should I play first?
Choose Adeptus Mechanicus first if you want the more familiar tech-priest campaign; choose Necrons first if the new playable perspective is the main appeal.
Q: What are the best units and builds in Mechanicus II?
Necron Warriors and Skitarii Rangers are the safest first picks — they provide reliable damage and keep your faction resource (Dominion or Cognition) flowing. Add Canoptek Wraiths as mobile bodyguards for your leader. For a first build, focus on leader protection, cover discipline, one reliable ranged threat, and resource stability. Avoid replacing all core infantry with flashy specialists until you understand mission pacing.
Q: Are the Leagues of Votann playable in Mechanicus II?
Current store descriptions focus playable campaigns on Adeptus Mechanicus and Necrons. Preview coverage says the Leagues of Votann appear in the story, but not as a playable third campaign faction.
