A cloaked figure is walking in a vast desert, when suddenly the ground starts to shake and an object rises from under the sand. As the object unfolds it becomes clear that it is some sort of alien entity. The cloaked figure looks up while clutching a small device that reminds him of his departed friend and of his mission to get them back. As he is looking up at the alien machine, it emits a sonic pulse that pushes the hood off the figure and reveals him to be Master Chief. The alien body is a Forerunner creation.
The Forerunner being is hovering above the crater it has left in the desert sand. Master Chief is looking up at it and realizes that it is arming its weapons. Quickly Chief takes off sprinting for the tall rock pillars he saw in the distance, ones that he could use as cover against his Forerunner enemy. Explosions are going off near Chief as he is running and trying to get to cover, but the combination of a 2 ton suit of armor and the lack of stability of sand is making it harder for Master Chief to reach the protection of the rocks. With every step, Chief seems to get slower and slower and the Forerunner is getting closer and closer.
At this moment all that Chief could think of is, "Just a little bit further."
The Forerunner enemy is lining up for what would seem like the fatal shot. As it fires, Chief dives to his left just in time to avoid the attack. The Forerunner flies by and Chief is picking himself up out of the sand. Now the enemy hovers between Chief and the protection of the rocks. Master Chief rips off his cloak and grabs his assault rifle from its holster on his back. Both stayed still, waiting for the other one to make the first move. It was Chief that decided to move first. The Spartan takes off sprinting once more in the direction of the rocks, all the while firing his rifle at the Forerunner the entire time. The bullets are bouncing off its armor, barely fazing the huge machine. Even though his attack proves to be futile, it does provide the distraction that allows Chief to get close to the Forerunner, making it fly up and turn around in order to get a shot off. This gives him enough time to dive and roll into cover, just as the Forerunner enemy turns around and fires, barely missing and hitting the rocks instead.
The Forerunner is circling outside the rock pillars trying to find a shot. While inside, Chief reloads his rifle and takes in his surroundings. He sees one of the rocks has fallen, making a ramp and the Forerunner object can be seen moving outside towards it. He returns his rifle to his back and says, "Let's see if this works." He takes off running up the ramp. The Forerunner is moving right into the path that Chief wanted. At the edge, Master Chief jumps and is able to grab hold of one of its wings. It spins and dives trying to shake off its invader. Chief is holding on with all his strength while his feet are flailing back and forth. He is able to get a foot hold which helps stabilize himself on top of the Forerunner. With himself balanced, he is able to grab a grenade from his belt. The Chief pushes the button to arm the frag and wedges it in the wing. Just as he gets the grenade in place, he gets thrown from the Forerunner enemy. He is sent flying through the air only to slam his back onto the rocks and fall to the ground. He weakly lifts his head just in time to see the grenade detonate. The explosion destroys one of the wings on the Forerunner machine. It crashes into the desert kicking up a dust cloud of sand. The dust cloud covers the entire area and when the sand settles, Master Chief is standing next to the Forerunner looking down at his defeated enemy.
As he walks away, one thing enters his head and it was one of the last things Cortana said to him, "It worked. You did it. Just like you always do."
