Off in the distance, Sgt. Lyrus of storm trooper squad "Omega," could see two towering dark figures moving up slowly. He zoomed in with his targeting array and saw that the creatures were hive tyrants. Slowly moving forward. All had huge scything talons, and venom cannons. Sgt. Lyrus winced. He knew how powerful those creatures were and he radioed in to Mclane. "Sir," he said, "we have three hive tyrants moving in on our position. They are approximately 1km. away, over." "Very well, Sgt. I will relay this tactical data to our troops up front. How are you holding up out there?" Mclane asked. "Good sir, we have one wounded but it's only a minor but from a borer beetle." "Good, carry on. There is a group of raveners trying to make it up the mountain to your position. I advise you take them out now before it's to late. Also be advised that it will be very difficult to obtain more supplies so use what you have wisely. Mclane, over and out." Sgt. Lyrus ran to his squad mates who were crouching behind rocks, firing concentrated rounds from their hell guns. One storm trooper, armed with a grenade launcher fired a frag grenade at a squad of termagants down range. "Good shoot Regi!" Yelled another squad mate to the grenadier. "We have a group of raveners moving in on our position from the pace of the mountain, open up of them!" Lyrus yelled. His squad complied and soon the raveners were reduced to only two scattered creatures quickly fleeing the fight. "Good job men, know open up on those genestealers!" Lyrus ordered. His squad began firing at the genestealers and soon they were dead. But there were plenty more targets at which to fire and Lyrus and his squad had soon dispatched a brood a hormagants. Down bellow on the wall Lyrus saw a soldier writhe as though in immense pain and then lay still. Lyrus knew what had hit the poor man. It was a shot from a devourer, which had sent a group of deadly parasitic worms at him that had devoured the insides of the helpless soldier. Lyrus had seen many soldiers die in his time but there was something about the death of that soldier that enraged him beyond his control. He spotted the offender, a roaring Tyranid warrior. Lyrus fired 15 shots from his hell pistol at the fowl beast, bringing it to the ground it's blood coating the rock which it had been standing on.

Lt. Seluns ducked down low. He crawled over to one of the soldiers in the 5- man squad. It was a soldier named James firing through a slit in the wall. Seluns taped him on the shoulder. James looked around and Seluns gestured for him to follow. Seluns burst up and ran along the wall to the rest of his squad James close behind. Selunds dived to avoid a needle fired from a venom cannon wielded by a Tryanid Warrior. "You alright sir?" Asked one of his squad mates. "I'm fine." He replied getting up and crouching. "There's a brood of Tyranid warriors that's pinning delta squad down lets get them!" Seluns said. "They are over on our right, on my command we pop up and open up on them." "Aye sir!" His squad replied." "Alright, one, two, three, now!" Seluns screamed. He leaped up and started shooting at the warriors. The rest of his squad followed suite, his missile launcher team blasting them with two fragmentation rockets before the warriors could even turn to look. The Tyranids were blown off their feet by all the fire and quickly went down. Then Seluns saw something that chilled his blood. A brood of hormagants was scaling the wall. Seluns yelled to the squad (squad "Alpha") about the threat. They Quickly crouched and aimed their weapons at the top of the wall ready to blast the aliens when they got over it. As the hormagants got to the top they were blown off the wall by the sheer amount of fire.

Mclane saw the hormagants swarming over the wall and quickly relayed the message to all of his squads. Mclane knew that if the hormagants were left unchecked they would kill all of his guardsmen on the wall. But Mclane wasn't worried he was quite sure his guardsmen could handle the threat.
