Astartes II Teaser Trailer: What the September 2026 Warhammer+ Reveal Confirms
Astartes II is scheduled for Warhammer TV in December 2026 through Warhammer+. The teaser confirms the presence of Deathwatch and Terminators, but not an exact premiere date or the finished animation’s runtime.
The short answer is clear: Astartes II is scheduled to arrive on Warhammer TV in December 2026 through Warhammer+. Games Workshop’s September 18, 2026 teaser confirms the release month, but the announcement gives no specific December day. (Official teaser)
What does the September teaser actually confirm?
The teaser is 42 seconds long and features Deathwatch and Terminators. That makes it useful as a signal of the project’s direction, but not as a synopsis. A short teaser can identify the forces being placed in the spotlight without establishing the story, episode structure, or final scope of the animation.
That distinction matters because the 42-second figure belongs to the promotional video—not to Astartes II itself. The official preview also says the sequel will be significantly longer than the original Astartes animation, so the teaser’s runtime should not be mistaken for the finished project’s length.

Where will Astartes II be available?
The official release path named in the announcement is Warhammer TV, with access through a Warhammer+ subscription. For a U.S. viewer, that makes Warhammer+ the relevant service to monitor rather than treating the teaser as an announcement of a general free-video release. The Warhammer+ site is the service’s official entry point. (Warhammer+)
This also clarifies what the December announcement does—and does not—tell viewers. It identifies the platform and month, but it does not provide a premiere day, a full runtime, or an episode count on the cited pages.
What should fans take from the reveal?
The most reliable expectation is therefore narrow: Astartes II is an official Warhammer+ project targeted for December 2026, and Deathwatch and Terminators are part of the material being previewed. Anything more specific about the plot or release schedule would go beyond what these official pages establish.
For planning purposes, December 2026 is a release window, not a date to put on the calendar yet. The teaser answers “Is the sequel coming, where will it appear, and when is the current window?” It does not yet answer “Which day, how long, or exactly what story will unfold?”
