Our main character is Mack (you can decide his last name.)
He has short orange hair and jade colored eyes, he has a medium sized scar on the back of his neck/right shoulder from a injury in his childhood (child abuse, hinting one part of his cowardliness.) He's 5' 7", (7 Reference, always need at least one.) He has an average body, nothing special, except another scar on his lower back, a small one, from a knife (also child abuse). As soon as he turned 18, he enlisted into the UNSC to get away from his family.

"Fall back, fall back!"
"Mack, get up!"
Mack's eyes darted around the craters and battered field, he felt a burning sensation on the back of his head, as he tried to move his arm, he felt nothing and couldn't move it, as he looked to his arm, he found it was missing, he then felt something oozing down on the side of his body, he looked down, it wasn't blood, but something green.
"W-what....?"
As he tried to crawl towards the sound of his squads gun fire, he stopped, realizing he is alone. No one is there, it's no longer day, there's no covenant, no UNSC, no more battered fields or crater, just darkness.
"A-am I dead....?"
