Warcry

An upcoming specialist game for Age of Sigmar and successor to Skirmish, Warcry is advertised as combining aspects of Warhammer Underworlds and Kill Team, and promises a much more complex and nuanced take on the various factions of Age of Sigmar, presumably by going into detail for small-scale forces that don't have much of a presence in the wider battlefields. The (few) models we've seen look awesome. From what we've been told and shown, it appears to be very Chaos focused, being set in the Allpoints, which is a certain somebody's favourite haunt.

Warbands

Iron Golems

Chaos Duardin and an Ogor buddy

Hailing from the Realm of Metal, these warriors are renowned for the quality of their smithing, believing themselves chosen by Archaon himself to forge arms and armor for the Slaves to Darkness. They also have both Duardin and Ogors.

Untamed Beasts

Will apparently involve more of the fauna of Chaos, including creatures like Furies and Raptoryxes.

The Splintered Fang

A Chaos murder cult from the Cobra Command Realm of Life, these guys are another multi-race warband, including both humans and aelves, and have a Spartan/Gladiator aesthetic. And snakes. They really like snakes.

Corvus Cabal

A tribe from Ulgu who worship Chaos in the form of a crow called the Great Gatherer, and as such have a heavy crow theme going on.
