Space Marine 3 Will Inherit Toxic Commando Tech as Saber Targets Bigger Swarms, Areas and Smarter AI

Warhammer 40,000: Space Marine 3 may be a long way from revealing its full battle plan, but Saber Interactive has outlined an important part of the machinery beneath the ceramite: the technology advanced through John Carpenter’s Toxic Commando. Development chief Tim Willits says the studio’s work on its co-op zombie shooter is part of a continuing technical path that runs from World War Z, through Warhammer 40,000: Space Marine 2, and onward into the next Space Marine game.

The immediate implications are deliberately broad rather than a list of confirmed features. Saber has not announced vehicles, larger squads, an open world, new enemy factions, or a release window for Space Marine 3. What it has indicated is that its proprietary systems are becoming more mature, with ambitions around bigger enemy crowds, more expansive locations, and better artificial intelligence. For a series built on making players feel like they are standing in the path of a galaxy-scale apocalypse, those are meaningful pillars.

One technology lineage, from zombies to Tyranids

Toxic Commando centers on cooperative survival against enormous zombie hordes. Saber’s expertise in rendering and managing large swarms was already visible in World War Z, then became a major part of Space Marine 2’s Tyranid encounters. The announced third Space Marine game will use that accumulated experience rather than starting from a blank slate.

That does not mean Space Marine 3 will simply repeat the formula of fighting Tyranids in another set of missions. Instead, the relevant lesson is technological: the studio is improving how it populates a battlefield with a great many threats, how those threats navigate the environment, and how a squad can engage them while the game remains readable and responsive. The exact visual result could change substantially depending on the campaign setting and the opponents eventually chosen.

Willits described Toxic Commando as a valuable stage in Saber’s wider process of building games designed around loud, social, over-the-top action. He also said the project was profitable for Saber, even though its March launch did not meet the publisher’s expectations. Those two assessments can coexist: a title may land below a publisher’s target while still generating a commercial return for the developer and producing tools the studio can bring to later projects.

That latter point is especially relevant to Space Marine 3. Big technology investments rarely belong to a single game forever. The systems used to support high volumes of enemies, co-op interactions, environment streaming, vehicle behavior, or AI routines can become building blocks for several productions. Saber has also named its forthcoming Jurassic Park project as another game using the same underlying technology.

What Saber actually said about Space Marine 3

The clearest themes attached to Space Marine 3 are larger swarms, larger areas, and improved AI. These are development directions, not a confirmed feature checklist. Still, they point toward an effort to increase the scale of the action beyond Space Marine 2 while maintaining the weight and clarity that helped define its combat.

“You can see the bigger swarms, you can see the bigger areas, you can see the better AI,” Willits said while discussing the maturity of Saber’s technology.

Cars came up as an example of a capability present in Toxic Commando that Space Marine 2 did not use. Willits specifically cautioned that this should not be treated as confirmation of cars in Space Marine 3. The useful takeaway is narrower: Saber is expanding the range of systems its engine and tools can support. Whether any of those systems becomes a Space Marine 3 mechanic will depend on the game’s design rather than the mere fact the technology exists.

For fans, that caveat is important. A vehicle-capable toolkit could theoretically support everything from brief transit sequences to armored ground combat or an entirely different kind of mission. It could also be irrelevant to the final game. A Land Raider or gunship mission remains speculation, not an announced element. The Imperium already has enough paperwork without declaring every technical possibility an official requisition.

Could the squad get bigger?

One natural question is whether broader levels and denser enemy attacks might allow Space Marine 3 to raise its player count. Space Marine 2 is designed around three-character squads, although modders have changed that limit. Saber has previously characterized three players as the right number for that game’s balance: a fourth Space Marine could make encounters too manageable, while scaling assaults upward enough to justify an extra player was described as a much harder challenge.

Newer swarm and AI technology might make different designs possible, but no change to the three-player structure has been confirmed. Bigger hordes do not automatically mean more players. They could instead create a stronger sense of pressure for the same squad size, enable broader tactical routes, or permit battlefields that host more simultaneous activity. A larger map can also be made to feel bigger through sightlines, objectives, verticality, and distant warfare rather than an increase in playable bodies.

The strongest reading of Saber’s comments is that Space Marine 3 is pursuing more capability and flexibility. Exactly how that flexibility is spent remains unknown. The studio could preserve the tight co-op arrangement that worked in Space Marine 2 while making its missions feel more spectacular. Or it could revise the structure. Until Saber says otherwise, neither outcome should be assumed.

Enemy speculation is still just speculation

Space Marine 2 gave Saber a very public showcase for Tyranid swarm technology. That success also creates a design question for its sequel: how does the studio retain the exhilaration of mowing through overwhelming masses without making the conflict feel too familiar?

Necrons are widely discussed by the community because of hints noticed in Space Marine 2, but Saber has not confirmed them as Space Marine 3’s central enemy. The same goes for potential returns of the Orks, the main foes in the first Space Marine, and ideas involving the Death Guard or Plaguebearers. Each could offer a very different use for the underlying technology. Orks could create chaotic bodies of infantry and ramshackle warfare; plague forces could emphasize relentless attrition; Necrons could demand a different rhythm of movement, durability, and battlefield control.

There is a distinction worth keeping in mind: Saber’s engine may be able to put more enemies onscreen, but faction choice and encounter design decide whether that capacity is exciting. An enormous crowd is not enough on its own. Enemy silhouettes, movement patterns, elite units, ranged threats, mission objectives, and terrain all determine whether a swarm feels like a dramatic last stand rather than a moving wallpaper of targets.

Success gives the sequel a demanding target

Willits said Space Marine 2 has reached 14 million players, while World War Z has been played by 30 million people. He also pointed to the strong reception for Space Marine 2’s DLC and the usefulness of observing what the mod community enjoys. Those figures and that ongoing feedback give Saber a large audience to satisfy, but they also give the team practical information about which parts of the modern Space Marine experience resonate most.

The stated goal is not merely to make another game using the same tech. Saber wants to make a sequel that improves on Space Marine 2 while respecting Warhammer 40,000’s established setting. That is a sizeable mandate. The second game’s popularity creates confidence, yet it raises expectations for mission variety, enemy design, co-op systems, and spectacle in equal measure.

For a related example of how studios are weighing the value of smaller and larger projects in the present industry climate, see this look at Double Fine’s discussion of an indie return and smaller-game opportunities. Saber’s situation is different, but Toxic Commando illustrates a comparable idea: projects can have strategic value beyond the obvious question of whether they become a blockbuster.

No release window, and no generative AI in development

Space Marine 3 currently has no announced release window. Saber’s public comments amount to an early technical snapshot, not a timetable. Fans eager for concrete information on platforms, gameplay modes, campaign setting, factions, squad size, or vehicles will need to wait for future reveals.

One production detail has been made explicit: Willits has said that generative AI is not being used in the development of Space Marine 3. The clarification followed online criticism related to generative AI use in Saber’s Rideshare Simulator.

For now, the defining promise is a familiar but potent one for the 41st Millennium: more battlefield. Saber is positioning Toxic Commando not as an isolated zombie detour, but as another piece of a technical foundation meant to support future games. If that foundation delivers on bigger swarms, more substantial spaces, and smarter AI, Space Marine 3 could turn its inherited engine work into a much larger war. The Emperor, presumably, will expect the frame rate to hold.
