Kill Rig

The Kill Rig is an Awesome and new Ork War Carriage showcased in July 2021 as part of the new Beast Snagga line. Unlike say, the Space Wolves' Stormrider which looked fucking retarded and out of place even for the Corgi Marines, the Kill Rig looked thematically sound and in-character for the Orks.
Overview
Towed by a mountainous Tramplasquig and home to a wide-eyed Wurrboy, the Kill Rig is a true engine of destruction that ploughs through infantry and vehicles alike. By amplifying the psyker’s Waaagh! energy through a contraption known as the wurrtower, its Beast Snagga drivers can blast lances of pure Orky power at their foes. In a nutshell, it is a modern and up-to-date version of the classic Weirdboy Tower.
It also boasts several armaments, chief among them is a frontal canon and a side sponson. It also comes with two Saw Blades to slice any would-be boarder trying to derail the vehicle.
Hunta Rig

Hey! Feeling too squeamish over Perils of the Warp? Ain't feeling confident about a Psyker potentially ruining your entire ride? Don't worry, we got a vehicle for you!
Ladies and Orkmen, we introduce to you the Hunta Squig. A more...traditional form of Kill Rig that functions more like a Squig-drawn IFV.
Overview
Despite their reverence for the oracular nature of the Wurrboys, certain Beast Snaggas are loath to have such a volatile creature riding with them. Instead, they fit extra decks and grab handles to transport hollering mobs of their clanmates into battle, transforming their vehicle into a Hunta Rig.
A Hunter Rig has a similar weapons layout to the Kill Rig, the only main difference is that the wurrtower was removed and the weapons were simply re-arranged around the superstructure. In turn, both the side sponson and the frontal cannon become fully articulated turrets and the front of the Rig now has enough space to carry even more Boyz to the battlefield.
