From the preview:
Corpse Hammer Preview: Necrovanum Berserker
For preview we have the Necrovanum Berserkers. The Necrovanum Berserkers have both a ranged Venom Cannon as well as a heavy Necro Syckle for close combat. The Necro Syckle is unusually large for the Berserkers and is difficult to wield under their own power resulting in clumsy or ill planned strikes against the Nephalim Knights. However once per game the Berserkers may engage a Necro Charge through the tubes in their back which floods their body with a heavy amount of powerful toxic fluids embodying them with crushing brute strength and speed. This effect lasts two turns, afterwards leaving them in a more weakened state.
