Syama Pedersen’s Astartes is a striking piece of independently created CG animation that understands what makes Warhammer 40,000’s Space Marines frightening: they are not simply soldiers in oversized armor, but instruments of overwhelming, methodical violence. Across its five installments, the short turns a boarding operation into an exercise in mounting dread, establishing the Adeptus Astartes’ superiority without lengthy exposition. Its greatest achievement is making their power feel tangible—not through declarations of their legendary status, but through the terrifying ease with which they overcome resistance.
The film does an exceptional job of showing just how far above baseline humanity the Astartes truly are. The human defenders are not merely smaller figures standing opposite larger opponents; their desperate resistance provides a measuring stick for the Marines’ extraordinary capabilities. Against the squad’s speed, precision, and armored resilience, ordinary soldiers seem tragically outmatched. What would be a desperate, chaotic battle for a human combatant appears almost routine to an Astartes. The contrast makes these warriors feel genuinely superhuman rather than simply well-equipped, exposing the immense gulf between humanity and the living weapons created to fight its wars.
Pedersen’s animation strengthens that distinction by reconciling enormous weight with startling agility. The Marines’ footsteps suggest industrial machinery, yet their movements become sudden and predatory when combat demands it. They never seem burdened by their bulk; their armor feels inseparable from their bodies. Their brutality is equally convincing because it is procedural rather than theatrical. They do not posture, celebrate, or waste movement—they identify threats and eliminate them. That absence of visible excitement makes their violence more unsettling: this is not uncontrolled rage, but the disciplined application of lethal force.
The visual and sonic presentation gives that violence its crushing impact. Claustrophobic corridors emphasize the Marines’ imposing size, while heavy footfalls and thunderous weapon reports make every advance feel consequential. Detailed environments establish the setting’s grim atmosphere without burying the action beneath visual clutter. When the mission encounters stranger powers and unknown technology, the short shifts toward cosmic horror, reminding viewers that even these formidable warriors inhabit a universe capable of threatening them. Its sparse exposition occasionally sacrifices clarity, particularly for newcomers, but the resulting mystery makes the world feel larger than the mission unfolding onscreen.
That such an assured production began as one animator’s independent project makes Astartes even more impressive. Pedersen’s work caught Games Workshop’s attention and led the company to hire him in 2021 to create official Warhammer animation—a remarkable transition from fan creator to professional contributor to the universe he admired. The recognition feels earned because the short does more than reproduce familiar armor and iconography: it translates the Space Marines’ defining qualities into movement, sound, and atmosphere. Their superiority is not simply part of the background lore; it becomes the organizing principle of every encounter.
Pedersen later contributed as a layout artist to “Warhammer 40,000: And They Shall Know No Fear,” the Astartes-centered episode of Amazon Prime Video’s Secret Level. His contribution formed part of a collaborative production rather than another solo undertaking. It is, in this reviewer’s estimation, the anthology’s best episode, carrying forward the same understanding that makes Astartes so compelling: Space Marines should feel simultaneously disciplined, brutally efficient, and terrifyingly inhuman. His involvement provides a fitting continuation of the original short’s achievement, bringing that distinctive approach from an independent fan project into a major studio production.
