Astartes II gets new trailer with Deathwatch and Terminators

The company says Astartes II will be significantly longer than the original Astartes. No exact runtime was given.

A social post from @40kWorldview calls the teaser “Coming December” and describes a Deathwatch unit exploring a Space Hulk. That December mention was not separately confirmed as an official release date in the source material provided.

What happened

Games Workshop released a new trailer for Astartes II as part of the Big Autumn Preview. That gave the Warhammer 40,000 project another official update after the sequel had already been announced. The trailer was shared on 18 September 2026 and offers the clearest new look at the project since the earlier reveal.

The trailer confirms the presence of Deathwatch and Terminators. According to Games Workshop, Astartes II will also be “significantly longer” than the original Astartes, but the company did not reveal a runtime or episode length. That means it is still unclear how much bigger the sequel will be compared with the original project.

Astartes II is the sequel to Astartes, the well-known Warhammer 40,000 animation by Syama Pedersen. The source material links Pedersen to the official sequel, but does not go into detail about his exact role. It does note that he is later involved in making the sequel, but provides no additional production credits, release details, or technical specifications.

The @40kWorldview social post adds another layer of context to the teaser. Its embed text says “ASTARTES 2 teaser Coming December” and describes a Deathwatch unit investigating a Space Hulk. That is useful as a description of the post itself, but the December mention is not separately confirmed by Games Workshop or another official source in the material provided. The Space Hulk description should therefore be read as social post context, not as a standalone verified synopsis.

Background

Astartes II is an official sequel set in the Warhammer 40,000 universe. The project builds on Astartes, the animation Syama Pedersen previously made that drew a lot of attention in the Warhammer community. The new trailer shows Games Workshop positioning the sequel as an expansion of that earlier work, with recognizable units like Deathwatch and Terminators on screen.

The update mainly provides concrete information about the trailer and the tone of the project. The source confirms that the sequel will be longer than the original Astartes, but gives no exact duration, no episode structure, and no release date. As a result, the only firm takeaway is that Games Workshop brought the project back into the spotlight on 18 September 2026 during the Big Autumn Preview.

The @40kWorldview social post is the only place in the provided sources where a month is mentioned. Its embed text includes “Coming December,” but without further confirmation that should be treated as post text rather than an official date announcement. The same post also mentions a Deathwatch unit and a Space Hulk, which fits the Warhammer 40,000 setting shown in the trailer.

Because the available source material does not provide extra details about the length, the exact release, or Syama Pedersen’s precise role, the core of the news remains the new trailer, the confirmed appearance of Deathwatch and Terminators, and Games Workshop’s statement that Astartes II will be longer than the original.
