Games Workshop Unveils Animation Slate at Big Autumn Preview: ‘Astartes II’ and Kharadron Overlords ‘Arkanaut’ Take Center Stage

Posted on by

Games Workshop’s Big Autumn Preview delivered major announcements for Warhammer animation fans, highlighting two flagship series heading to Warhammer TV. Headlines were dominated by the long-awaited teaser trailer for Astartes II alongside the premiere trailer for Arkanaut, a new Age of Sigmar series featuring the sky-faring Kharadron Overlords.

‘Astartes II’ Teaser Drops Ahead of December Release

The much-anticipated sequel to Syama Pedersen’s groundbreaking fan-turned-official project, Astartes II, received a fresh teaser trailer during the preview showcase. Astartes II will be noticeably longer than its original predecessor, allowing for broader narrative storytelling and extended action sequences. The animation is slated to premiere in December 2026 exclusively on Warhammer TV for Warhammer+ subscribers.  The teaser showcases high-fidelity 3D CGI animation, highlighting the lethal, tactical prowess of Space Marines as they engage lethal galactic threats.

Kharadron Overlords Take to the Skies in ‘Arkanaut’

Switching realms from the 41st Millennium to the Mortal Realms, Games Workshop revealed Arkanaut, a new animation centered around the Kharadron Overlords.

The series follows the steam-powered, profit-driven sky-duardin as they navigate treacherous skies, aboard massive airships armed with heavy aether-tech weaponry. Fans won’t have to wait long—the first episode of Arkanaut is scheduled to debut on Warhammer TV in October 2026.

Both reveals highlight Games Workshop’s continued push to expand the content lineup on Warhammer TV for subscribers. With Arkanaut landing in October and Astartes II closing out the year in December, autumn 2026 marks one of the densest animation release windows for the platform to date.
