Warhammer Underworlds: Thyrielle's Zephyrites

A brand new Lumineth Realm-lords Mastery warband arrives in Embergard — Thyrielle's Zephyrites, masters of anemology from the Hurakan temples of Hysh. Four fighters plus a unique vulpine spirit token named Tzul whose board placement drives the entire playstyle. Friendly fighters in Tzul's windblown lines gain gravity-defying leaps and improved saves; enemies count as permanently Flanked. The warband Inspires on a successful attack.

The Horus Heresy: New Plastic Kits

Legiones Astartes and Solar Auxilia players both received significant reinforcements, with several resin classics making the jump to plastic.

Spartan Prometheus Assault Tank

A new variant of the iconic Spartan Assault Tank capable of carrying entire squads of power- or Terminator-armoured warriors.

Available to both Loyalist and Traitor forces with a choice of pintle-mounted weapons and accessories.

Charonite Ogryn Section

Biochemically altered hulking warriors for the Solar Auxilia, squeezed into armoured void suits and pumped full of combat stimulants. They wield cybernetically implanted claws, blades, shredders, and crushers — designed to let regular humans go toe-to-toe with post-human Space Marines.

Rapier Fire Support Battery

Heavy weapons platforms delivering long-range firepower via quad launchers (“Thudd Gun” — frag or shatter shells) and mole mortars (which fire into the ground and detonate beneath the enemy).

Rapier Direct Fire Battery

Close-support platforms with a choice of gravis heavy bolter battery, gravis multi-laser array, or laser destroyer.

Journal Tactica: The Battle of Tallarn — Part 1

Updated rules for the new Rapiers, Charonite Ogryns, and the Spartan Prometheus Command Tank, focusing on one of the biggest battles of the Horus Heresy.

Middle-earth SBG players got a fantastic set of reveals centred on the conflict in Rohan, with long-awaited cavalry and commander updates alongside a brand new narrative campaign journal.

Riders of Rohan™

The mounted counterparts to the refreshed Warriors of Rohan are finally here. The new plastic kit builds six Riders with a variety of weapon options — four can be assembled with a hand weapon or throwing spear (with bows slung across their backs), while two have bows drawn with hand weapons stowed. All six horses are unique sculpts, and any Rider can be mounted on any horse for maximum variety in massed cavalry ranks.

Warriors of Rohan Commanders

A new command set to lead your Rohan battleline, building three miniatures:

• Captain — with a choice of armour or heavy armour, and helmeted or bare head options.

• Warrior with War Horn.

Hill Tribes™ Commanders

The enemies of Rohan also get a new command set, building three miniatures:

• Hill Tribes Chieftain — with a choice of hand weapon and shield, or two-handed weapon. Can also be built as the Wild Man Oathmaker for Wild Men of Dunland armies.
• Hill Tribesman with Banner.
• Hill Tribesman with War Horn.

Middle-earth SBG Journal: The Burning of the Westfold

A new narrative campaign journal featuring 11 linked scenarios following Saruman's assault on Rohan — from the Fords of Isen, through Helm's Deep, all the way to the Ride of the Rohirrim at Pelennor Fields.
