Chapter 3: cleansing

A small squad of 12 ATV's raced down the empty streets of the abandoned city in search of the flood spawning grounds, the sewers. They went immediately to the sewage station management facility but it was devastated, there had been serious flood activity there. They proceeded on to the sewage lines and encountered the first flood. The chief jumped off the ATV just in time, a human combat form had launched itself at him and was smeared on the front of the light vehicle. All the marines and the two Spartans leapt out of their ATV's and started blasting away at the flood. The chief got up and opened up with his shotgun immediately blowing a two foot wide hole through the decaying body of one of the flood. Under the vicious assault of the marines the flood fell quickly, but then it started going wrong, one of the ATV's exploded killing two of the marines, and injuring one other. Master Chief pulled out a small med-kit and injected bio-foam into the small shrapnel hole in the injured marines' chest. Then the chief walked over to the now overturned ATV's and he took an abandoned ghost he found in a side alley. They sped off into the sewer finding surprisingly little opposition from the flood. They dismounted and began to look for a base of sorts in the tunnel. Then came an all too familiar sound, that tiny tinkling of flood feet on plate metal. From the skyscraper burst a tsunami of flood infectors, they swarmed toward the small group of soldiers, just turning to run when the chief barked for them to stay and fight them off. They brought up their riffles without protest, but it was clear they weren't happy about sticking around to be flood food. They opened fire one round from their riffles taking out five of the tiny things, but that was nothing compared to the chief. He was using his pistol to shoot through multiple flood causing chain reactions throughout the entire mass. Soon the flood overtook one of the marines and converted him. He was quickly cut down by the marines overpowering assault rifle fire.
They slowly continued down the tunnel pointing flashlights and weapons everywhere. Then out of the piercing darkness cane a new beast, an infected dog. It had tentacles growing out of its back and each leg; its head had been torn completely off to allow room for the sensors the flood used. The terrible dog launched itself toward the frightened soldiers but was suddenly stopped as the chief grabbed it by its legs and smashed it into the walls; crushing its ribcage and killing the infection inside of it instantly died. The soldiers stood amazed at the master chiefs amazing strength and speed.
Silently he marched to the dead dog, at one time it was a monstrous mastiff, and it had just been infected. The chief turned and commanded the soldiers to head back to base leaving him most of the ammunition, he didn't want to risk their lives in this hellhole he had uncovered. They went to their ATV's and sped off to the base. The chief loaded onto the ghost and went deeper into the tunnel to hell.
