The Master Chief hadn't noticed that 20 Hunters were in the room behind him. They saw him first; five of them charged their weapons while the others charged straight at the Chief. He dodged them as fast as he could, taking a few scratches but still surviving and aimed his MA5B right between the shoulder-blades of one of them. He fired and had a clean shot.
'One down, a lot to go.'
The Hunters that had been charging their weapons fired. The Chief jumped over the blasts, did two flips and jammed his foot into one of the Hunter's head. He then ripped off the arm of the Hunter and used its plasma cannon to kill one of the other Hunters off. He slammed his MA5B into another's back and dropped it to finish off three more with his M6D.
He was being overrun by Hunters, soon they would kill him or more would come to finish the job. He had to win, to survive was his mission. He had done things like this before, but never this intense. They were so close range that their weapons would destroy them too if they fired, but they didn't care. He had only one choice; he attached a plasma grenade to one of the Hunters and ran as fast as he could away from the area. It exploded killing all of the Hunters in one blast.
The Master Chief returned to the room, he decided to take one of the Hunters' shields for himself. He kept going on in the ship, hoping that there weren't any more Hunters on board this ship. On and on he went again finding the additional patrol of Grunts and Jackals. A few Elites got in his way but they went down easily. He was close to the control room he guessed from past experiences, if not this ship was different from the other Covenant ships he had been on.
He ran rigorously down the hallway lugging the giant shield all the way. He found more Grunts, a larger patrol than he had seen yet on the ship. 100 Grunts sat at the ready to attack the Master Chief, behind them were 28 Jackals and 15 Elites. He immediately jumped over plasma blasts from the Jackals and Grunts. Once he landed he threw the shield in their midst crushing a good amount of Grunts, then pulled a 360° spinning kick in a circle of Elites knocking down three of them and missing the rest. He pulled out his assault rifle and shot a few Jackals in the backs killing them then ran over to the Grunts and smashed seven of them under his boots and on the eighth he jumped off of its head and over and Elite who was about to strike him down. In midair he tossed his last frag grenade at them and ducked under the shield he had thrown earlier. The grenade only kill about 50 of the Covenant forces left in the hall. He switched over to his M6D and finished off the remaining aliens.
Once in the control room he searched the cameras for any activity on the ship. None, he had killed every last Covenant on the ship. He let Cortana do the rest; she fired the plasma cannons at the other ships attacking the Ubërtomb. Some of the ships fled while their comrades were being destroyed by a combination of plasma and MAC cannon fire. The Master Chief could tell it wasn't over by a long shot; but now he had to get back and get some well deserved rest.
