Ga'duk stood surprised at the marine's speed, confirming what Thorn had said at least in Ga'duks mind. The soldier with the auspex scanner looked down to see the horde of blips converging on them "by the Emperor" he muttered. The sergeant shouted orders knowing full well that each and every one of them would die, even with the strength of a Space Marine and an Ogryn. Genestealers charged from bothsides of the hallway and a few managed to slip through the vents. "Kill them! Kill them all! For the Imperium!" shouted the sergeant drawing a Chainsword. Although the acute listener could hear the primal fear defiance of circumstance in his voice. Ga'duk however only heard the order to 'Kill them all' which was nice and simple. Las bolts flared around him and the groan of a chainsword biting flesh echoed down the halls, drouned out by the skittering of hundreds of taloned grotesqueries. Ga'duk bellowed a warcray "Fer da Empoor!" utterly without fear, because he knows the Emperor protects just as surely as he knew the Emperor got his illegible letters.

Ga'duk Charged down the hallway firing a shell from his grenade launcher blasting a score of the monstrosities into little more than grease stains before letting the gauntlet fall and hefting his axe. Once he closed with the horde he was all they could focus on, between his size and the reach of his axe none could get around him from that side. His axe took several at a time with long sweeping strikes that left deep gouges in the walls and floor. He heard shouts of fear and screams of pain behind him, but he dared not look back as it would take only a moment for him to be bowled over by the shrieking beasts. 

He held his side of the hall for what seemed like hours but was likely only a few moments, the monsters slowed their advance giving Ga'duk a momentary respite. He had killed easily a hundred of the beasts leaving a mound of broken bodies before him. he stared down the hallway and could still see dozens or hundreds of the creatures beyond, but they had stopped throwing themselves at him. It took him a moment to realize that he was otherwise alone in the hallway, no sounds of fighting behind him, no shouts of pain or victory just the scratching at the walls. He dared a brief glance behind him, most of the soldiers were corpses torn to shreds, however he was somewhat sure a few were missing. There were many gene-stealers carved to pieces or gunned down. While he was, slowly, processing this one of the more adventurous genestealers had crawled over the mound of its fallen and lept to claw at the Ogryn. It was however caught on his shield trying to clamber over the tower of pas-steel and eat a significant portion of Ga'duks face. In reply, he headbutted the creature and crushed it between is inhumanly though skull and his shield granting him savage warpaint of green slime. 

"Uhh, Sarge?" Ga'duk asked somewhat loudly triggering his vox, which broadcasts widely to ensure his transmissions are picked up by [i]someone[/i]. he continued backing away trying to keep his eyes on the mound of genestealer corpses, the vents and trying to pay attention if his sergeant or Thorn was alive or anyone else. While he backed up another few steps dozens of the genestealers started following him. "Uh-oh" he mumbled trying to think of a way out. He instinctively knew that his inhuman endurace and strength would not win againt the hordes of creatures, even with the emperor on his side. Glancing back every couple steps he noticed a bulkhead that was missing a door. He knew there was an answer around him somewhere. The gears were grinding in his head just as the creatures charges. Ga'duk ran through the door way ducking to allow his bulk through, his shield on the other hand didn't fit at wedged in the door way. The genestealers crashed against it, dozens of them desperately trying to claw through the thick slab of armor. Ga'duk yanked at the shield a couple times entirely blocking off the passage and permenantly wedging the way closed. He yanked at the shield again, but half way through his pull he realized that he was safe, or the monsters couldnt get to him from this direction at least which was his most pressing concern. He turned and looked down the hallway, no monsters from that direction but he was alone. Which presented a very serious problem, He doesn't work alone someone needed to give him direction. He put the grenade launcher on his left hand and held the axe in his right and started walking. He wasnt sure where to or who he would find but he was alone, except for the Emperor obviously.
