Saber Interactive to use Toxic Commando swarm tech for Space Marine 3
The studio is leveraging a proprietary pipeline to scale horde battles and AI for the next Warhammer installment.
Saber Interactive will integrate matured swarm technology from John Carpenter's Toxic Commando into the development of Warhammer 40,000: Space Marine 3. The move signals a strategic effort to scale the technical capabilities of the studio's most successful licensed franchises.
Saber CCO Tim Willits revealed that the proprietary swarm engine—the same foundation used in World War Z and Space Marine 2—has evolved through the development of Toxic Commando. This progression is expected to enable Space Marine 3 to feature larger enemy swarms, expanded play areas, and more sophisticated AI. While publisher Focus Entertainment described the launch of Toxic Commando as falling below expectations, Saber maintains the title was profitable and served as a vital "brick" in the company's technological wall, according to Willits.
A Legacy of Hordes
Saber Interactive has built its reputation on "swarm" gameplay, specializing in managing massive quantities of on-screen enemies. This technical lineage began with World War Z, which reached 30 million players, and continued with the Tyranid hordes of Space Marine 2, which has attracted 14 million players.
Toxic Commando, released in March 2026, acted as a further iteration of this tech, testing refined AI and vehicular combat. By treating each release as a stepping stone, Saber is creating a continuous evolution of its engine that will now support not only Space Marine 3 but also upcoming projects such as Jurassic Park.
Expanding the Scope
The application of this matured technology suggests that Space Marine 3 may overcome several of the constraints seen in its predecessor. The refined swarm tech could potentially allow the studio to move beyond the three-player co-op cap and restricted environments of Space Marine 2.
By leveraging the AI and scale improvements tested in Toxic Commando, Saber could introduce larger-scale battles and new gameplay elements, such as Land Raiders or other vehicles, significantly expanding the scope of the third entry. Willits noted that the massive success of Space Marine 2 has made the development team passionate about ensuring the sequel is "even better."
Human-Led Development
Despite the push for higher technical fidelity, Saber is drawing a hard line on the tools used for the project. Tim Willits confirmed that Space Marine 3 will not utilize generative AI in its development. This approach stands in contrast to other internal Saber projects, such as the "Rideshare Stimulator," which does employ the technology.
As development continues, the industry will be watching to see if these technical gains translate into a fundamental shift in the Space Marine gameplay loop, specifically regarding player count and environmental scale.
