Face us, Xenos!

The roar of bolt rounds echoed wildly beneath the steelworks' vaulted roof, and scorching casings rained down around Kran's feet.

He was death incarnate. Every precise burst exposed another impostor for what it was and blasted it into scattered flesh.

His orders came through the Helmet comms, cold and clear in every squad member's ears, coordinating this merciless purge.

Yet just as he focused on clearing the threats ahead, a stench of rot and strong acid suddenly swept over him from behind and to one side.

The corpse of an "Imperium soldier," lying on the ground and seemingly dead, underwent a horrific transformation.

Its torso suddenly split like overripe fruit, skin and muscle torn and stretched from within by an unimaginable force.

Amid teeth-grating sounds of dislocating bones and proliferating muscle, a twisted, five-meter monstrosity abruptly rose behind Kran.

Scraps of uniform still clung to its main body, but at its center gaped an enormous maw of overlapping, slime-dripping teeth, letting out a shriek sharp enough to pierce eardrums.

In an instant, a soldier standing one meter eighty had swollen into this terrifying monster. The entire transformation had taken no more than a single breath.

Its enormous shadow engulfed Kran as it bore down on him with devastating force.

Kran did not even turn all the way around. In that critical instant, combat instinct replaced thought.

His right hand abruptly released the Bolter, letting it hang at his side on its tactical sling, while his fingers clamped like iron pincers around the hilt of the Chainsword slung diagonally at his waist.

"For the Emperor!"

Kran shouted his battle cry as he moved, pivoting, stepping forward, and swinging his sword!

The movements flowed together without a pause. The raging Chainsword screamed through the air, tracing a deadly arc from below.

BZZZZZ!!!!!
