Warhammer 40,000: Gladius - Onslaught Pack

Deploy 8 brand-new units with the Onslaught Pack on the battlefields of Gladius Prime. 

The new units will bring a new offensive layer and will unlock new strategic options for commanders. 

Canoptek Reanimator - Necrons 

Support walker unit that regenerates friendly Necrons units.

Like its Canoptek peers, the looming Reanimator’s core role is not destruction but maintenance of a Necron Tomb World. Its remit is to repair damage caused during combat, which it does with streams of nano-scarabs, rebuilding nearby Necrons while they still stand.

Mandrake - Drukhari 

Light skirmish infantry that causes fear and teleports to disrupt enemy formations.

Feared even by their Drukhari kin, the origins of the unnatural Mandrakes of Aelindrach are lost in time. They appear like the void incarnate, with their midnight skin, bone-white hair and freezing presence. In battle, they literally slip between shadows, emerging only to plunge their sickle blades into the living or sear their flesh with the cold-fire known as Baleblasts.

Vyper - Craftworld Aeldari 

Fast reconnaissance skimmer unit with a multipurpose missile launcher.

Following a Saim-Hann craftworld design, the Vyper sits somewhere between a jetbike and weapons platform. Despite its lightweight build and speed, these two-Aeldari vehicles can carry a variety of heavy weapons - though on Gladius Prime, they are known for using only versatile missile launchers.

Attilan Rough Rider - Astra Militarum 

Fast melee cavalry unit.

Horsemen may seem primitive in a galaxy filled with millennia-old horrors, but the Rough Riders of Attila long ago proved their worth to the Astra Militarum. The hunting lances they carry are their concession to modern tactics, with their melta-tipped variants even capable of punching through power armour.

The Rough Riders can use frag or melta lances in-game.

Sicarian Ruststalker - Adeptus Mechanicus 

Elite melee infantry which excels in prolonged battles.

The Sicarians are warrior-clades repurposed from the remains of grievously wounded Skitarii. Unlike their Infiltrator kin, Ruststalkers act as assassins, their transonic blades and claws fused permanently into their bionic appendages and pallid, puckered flesh.

Rubric Marine - Chaos Space Marines 

Elite infernal infantry unit.

These ornate suits of power armour are filled only with dust - the remnants of the proud Space Marines whose spirits are sealed within and animate them still.

Squighog Boy - Orks 

Heavy cavalry unit that excels at taking down large prey.

Riding four-legged Squigs into battle, these Beast Snagga boyz are nomadic Orks, predominantly from the traditionalist Snakebites Clan. Their goal is always to take down the biggest enemy on the battlefield - be that Tyranid, Necron or Ogryn.

Norn Emissary - Tyranids

Elite Synapse monstrous creature bred to annihilate strategic enemy targets.

Each Norn Emissary is spawned for a specific purpose, be it predating on a strategically gifted commander, abducting a knowledgeable prey-being at the behest of its Norn Queen, or some other ineffable task. Melding terrifying psionic potential with speed, agility and awful strength, the Norn Emissary is more than equal to its mission.
