Fatshark Adds Skitarii Alpha Primus to Warhammer 40,000: Darktide as First Adeptus Mechanicus Class After Years in Development

Today, Fatshark launches the Skitarii Alpha Primus, which becomes the seventh playable class in the game Warhammer 40,000: Darktide alongside the Veteran, Ogryn, Zealot, Psyker, Arbites, and Hive Scum.

It's the game's first representative of the Adeptus Mechanicus faction, too. In a pre-release presentation attended by Wccftech, Fatshark confirmed that the class has been in development since before the Hive Scum release, making it one of the longest-gestating additions to the game.

Fatshark always intended to add an Adeptus Mechanicus presence to Darktide, citing the strong player resonance with existing characters like Tech-Priest Hadron Omega-7-7. A full Tech-Priest was, however, ruled out because Tech-Priests do not typically operate at the strike-team level of Darktide's warband. The Skitarii were also seen as underexplored in video games, presenting an opportunity to collaborate with Games Workshop on a fresh representation.

The class ties directly into existing Warhammer 40,000: Darktide content: players who have been helping Hadron Omega-7-7 recover Tech-Remnants in the Deadside have triggered the in-universe justification, as the success of those missions prompted multiple Forge Worlds to deploy forces to Tertium. Hadron has now located an old Adeptus Mechanicus facility on Atoma capable of upgrading Skitarii Veterans into the more elite Alpha Primus variant.

A Unique Character Creation

The Skitarii required an entirely new body type, as the class's cybernetic nature made the standard human body unsuitable. The character creation takes place inside the inner sanctum of the recovered Adeptus Mechanicus facility. Players begin with a disfigured torso and head suspended in the machine and build their character from there. Because there was little established visual reference for what a Skitarii looks like beneath the robes, Fatshark worked extensively with Games Workshop using written lore, codices, and narrative sources to define this crucial aspect.

Customization options include:

• Four distinct personalities, matching only the Ogryn in range
• Forge World of origin: functions similarly to the Hive Scum's Gang choice, altering starting cosmetics; one option, Branx Minor, is linked to Atoma itself
• Bionic eyes (primary and secondary lens colors that remain visible through all headgear cosmetics)
• Cybernetic limbs: arm and leg models, primary and secondary metal textures, and a separate oxidation level setting; these also appear in first person
• Height: Skitarii are on average taller than the regular human classes
• Background options, as with other classes
• Voice Modulation System: the Skitarii are the only class that features a three-parameter system that can be tuned in real time during character creation. Pitch affects pitch and other effects in non-linear ways, occasionally letting the unmodified voice come through; Delay creates echo or multi-voice effects with unpredictable variations; and Distortion applies crunching effects that vary independently as the slider moves.
  

Unique Class Mechanics

The Swedish studio also implemented special mechanics for the Skitarii. Rather than a standard cooldown, the Skitarii's Combat Ability is governed by Capacitance Charges. Having one Charge allows the ability to be used; accumulating multiple Charges empowers it. Charges are generated primarily through killing Basic and Elite enemies, and through specific talent-triggered actions. Most Combat Abilities consume all available Charges on activation, except the Chordclaw Strike.

The default Blitz is an Artificer Servo Skull, a floating companion that shoots enemies and can complete Data Interrogation minigames autonomously. Two additional specialized Servo Skulls can be added through the talent tree:

• A Flamethrower Servo Skull for firepower and horde cleansing
• A Medicae Servo Skull for team support

Players can take both simultaneously if they choose to. The primary Servo Skull is also cosmetically customizable via in-game cosmetics.

There's also a new damage mechanic exclusive to certain Skitarii weapons and talents. When an Arc-capable attack hits an already Electrified enemy, the electricity arcs to the nearest enemy, dealing damage and Electrifying it too, which can chain across an entire group. If the initial target is not yet Electrified, the attack will Electrify them instead, setting up the Arc for follow-up hits. This mechanic supports cross-class teamwork, so a Psyker can Electrify enemies to set up Arc chains for a Skitarii ally.

A Massive Talent Tree

The Skitarii talent tree breaks entirely from the standard top-down layout: it starts at the center and expands outwards in a cog-and-wheel shape. This design was inspired by both the modular nature of the Adeptus Mechanicus and the class's identity as a flexible generalist. Players can even opt to skip Blitz, Combat Ability, or Aura talents entirely if preferred. The tree underwent approximately 15 major iterations during development, according to Fatshark.

The talents are loosely organized around four themes:

Theme	Focus	Example Talents
Melee	Melee combat buffs and triggers	Electro-Strike Conduit, Uncapped Arrestor
Ranged	Ranged buffs and synergies	Rad-Sink, Gunsmith, Ammunition-Restoration Pod
Support	Aiding squadmates	Power Overflow, Protectorate Protocol
Arc	Arc mechanic specialization	System Shock, Voltaic Burst, Weakness Analysis Doctrine

A Skitarii's Arsenal

The weapon selection was guided by a balance of lore authenticity, gameplay niche-filling, and synergy with the Arc mechanic. The design and class teams worked in constant communication to ensure weapons and talents supported each other. The new class has access to several exclusive weapons, including:

• Arc Maul — Electrocutes on normal hits and builds up to 8 charges; activating the weapon special enters an amped mode where each attack drains a charge and triggers an Arc. Strong stagger and crowd control, but reliant on Arc for peak damage; deals bonus damage against already-electrocuted targets.
• Paired Transonic Blades — Darktide's second dual-wield melee weapon: a Transonic Razor in the off-hand and a Transonic Blade in the main hand. Weapon special switches between two attunements: a wide, sweeping horde-clearing mode and a single-target armor-piercing mode with thrusts and vertical attacks. Pressing weapon special mid-chain performs a unique transition attack.
• Mechanicus Power Sword — Unlike the requisitioned Power Swords of other classes, this version is always in an active low-power state. Starts with 6 charges; each use of the weapon special spends one charge for a high-powered attack (tap for light, hold for heavy). Holding charges passively buffs normal attacks, creating a strategic trade-off between spending charges for burst damage or retaining them for sustained power.
• Galvanic Rifle — Semi-automatic precision rifle covering a previously empty niche in Darktide's arsenal. It inflicts serious damage per shot, with good armor penetration but low ammo capacity, and excels at weak-spot hits when aiming down sights.
• Arc Rifle — High-ammo, slow-firing weapon shooting instant lightning bolts. Applies electricity on each hit and Arcs to nearby enemies when hitting Electrified targets, potentially chaining indefinitely. Its long reload time requires careful ammo management.
• Phosphor Blast Pistol — High-damage hand cannon with limited accuracy that splashes Phosphor compound to nearby enemies on each shot. The debuff increases damage taken from all sources and makes attacks cleave through affected targets more easily. The visual effect burns armor off enemies to communicate the debuff state to teammates.

The Skitarii will also be able to wield various existing Warhammer 40,000: Darktide weapons, and another new shared weapon, the Plasma Gun Mk III, also available for the Veteran class. This weapon shifts focus away from penetration toward devastating explosions that trigger on hitting most enemy types.

Just like the previous classes added to the game post-launch, the Skitarii DLC costs $11.99 across all platforms, while a Deluxe Edition priced at $18.99 adds a Deluxe Class Outfit, Unique Deluxe Servo Skull skin, 6 Deluxe Weapon Skins, and a Deluxe Portrait Frame.

Alongside the Skitarii DLC, Fatshark also launched a free update that adds a new scavenge Expeditions zone that lets Darktide players experience the desolate badlands of Atoma at Dawn for the first time. The patch includes two new enemies (the Scab and Dreg Vanguards), new opportunities, quality-of-life improvements, electrifying environmental hazards, balance changes, and bug fixes.

Lastly, the Heretical Artifacts live event has kicked off: strike teams have been tasked with retrieving these stolen artifacts and returning them to Tertium's clerics. As players gather artifacts, they will be able to select one of two factions to join: the Adherents of Saint Messelina, which will bestow players with an increased coherency radius, alongside boosted attack and movement speed, or the Scourge of the Faithless, which endows players with increased damage, burn damage, and burn duration.
