Marcus Petersen was born in Anchorage, Alaska on October 1st, 1996.
At the age of 18 he joined the military with his older brother, Clayton. They were stationed in Chernarus before the outbreak was a worldwide epidemic. Their jobs were to keep peace and order during the beginning weeks of the outbreak. After the military left, Marcus and Clayton were left to fend for themselves after being left behind.
A couple weeks after Chernarus was overrun, Marcus and Clayton were trying to survive as a large group of infected overran their camp. Marcus, not being able to help, watched as his best friend and only brother got eaten alive. From then on, he has been surviving on his own in this massive apocalypse.
