Guards fighting back wave after wave of Tyranids in a plaza in a hive

Incurring losses left and right, our heroes know there is only one way this will end

at the sound of a mighty roar, they look over their barricades, seeing a seething mass of tyranids flow down the boulevard towards their position

right as the front rank is about to reach the first of the barricades, a mighty impact shakes the ground and knocks the guard to their backs

in an ocean of dust and smoke, they see a large machine that looks like it was shot from a cannon sitting in a crater in the middle of the plaza surrounded by xenos corpses, the metal still tinking from the heat built up

suddenly there is a crack as the explosive bolts on the machine go off, and ramps fall down like a flower petal, and 5 giants in drab green power armor emerge, spewing fire and death from their massive bolt guns

in stunned silence, the troopers watch as these demigods of war casually stride down the boulevard unleashing explosive fury into the xenos horde

after what could only have been 30 seconds, all became quiet, as what a moment before had been a seething mass of xenos warriors had become a sea of cracked chiton and leaking viscera

the 5 giants calmly regrouped, and began to grab items from within their massive transport

one of their number, with a stripe on his helmet and a small amount of ornamentation on his chest plate took out an auspex and began to study it

“Thank you for showing up when you did, lord.”

Alaric said, shouldering his lasgun. The massive helmet with glowing red eyes pointed his way

“The Emperor protects.”

the warrior put away the auspex and looked to his fellows, pointing down the boulevard

“The objective is 5 Kilometers in this direction. Move out, my brothers.”

with that, all 5 of the super human warriors turned that way and moved at a pace that would have been a full sprint for a man, but looked like a casual stroll for them

a moment later, they disappeared through the smoke and dust, leaving only their still cooling transport, roadway full of xenos corpses, and the brass cases of their bolter shells
