Halo 3 – Arrival
Hurtling towards Earth in a Forerunner spacecraft found on the second Halo was the elite, Master Chief, officially known as Spartan 117. Master Chief knew the Covenant had discovered Earth, a long kept secret of the humans, now common knowledge through the Covenant. As the Master Chief hurtled towards Earth he hit the atmosphere, the heat was intense. Then before he could do anything to slow his decent, he hit the ground. The Forerunner spacecraft had been destroyed leaving Spartan 117 lying there, motionless. The Chief was found by Sergeant Johnson, the Chiefs oldest and closest friend. As Johnson found the Chief he had his medic check for vitals, none were detected. Not wanting to leave his friend behind Johnson ordered his medic, "Radio for VTOL, heavy lift gear, we ain't leaving him here". Next thing Johnson heard something, at first he assumed it was his imagination so he turned to look. It was Master Chief "No, you're not" as he pulled himself up on Johnson. Johnson shocked and concerned about his friend didn't know what to say. "Crazy fool. Why do you always jump? One of these days you'll hit something stubborn as you are, and I don't do bits and pieces".
Before the Master Chief could recalibrate his armour he saw the Arbiter, an enemy of the chief he battled on the second Halo. He took Johnson's magnum running up to the Arbiter, grabbing him and holding the gun up to his throat. As he was just about to fire the weapon Johnson shouted out "Chief wait! The Arbiter's with us!". The chief looked at the Arbiter suspicious of his new ally but he had now time for feuds, the Covenant were here, on Earth and they had to be defeated. After the Chief re-calibrated his armour he took his weapons. Offered by a soldier led by Johnson, a Magnum and an Assault Rifle, standard issue within the USNC but in the hands of the Master Chief, all that was needed to defeat the Covenant.
Once the Chief was re-armed they made way to battle. Within minutes of leaving the Chiefs crash site they found Covenant, they were straight into the thick of it. Brutes, Grunts and Jackals all awaited them hell bent in taking the Earth to fuel their so called "Great Journey". At first the Covenant didn't see them but the Chief soon changed that, he took aim at one of the brutes, this one seemed to be the leader with his Magnum, when the Chief has the right aim he took fire, the brute being a tough creature took a whole magazine to kill, but Grunts and Jackals no had no leader to co-ordinate them. Then Johnson and his soldier moved in, all in turn led by the Chief. Like a machine the USNC Marines defeated the Grunts and Jackals and this small battle was over. Or at least they thought it was until a Phantom was sighted inbound, loaded with more Covenant. This battle had only just begun, as soon as the phantom was spotted the Marines took cover as the Chief quietly made his way to the phantom drop site. As he approached the phantom he found a plasma grenade dropped by one of the Grunts. When the covenant had left the drop ship the Chief threw his grenade into the Covenant, the grenade stuck to the Brute leader and detonated, destroying the Brute and the Grunts surrounding it. This battle was now over and the Chief along with the Marines moved on to the next area.
