Harry Allen is a man who keeps moving, carefully observing what’s ahead of him. He is observant when among other people and always stays cautious. While some would think he’s paranoid or scared, his heightened senses and quietness are his best defense. Harry worked several years for the Department of Defense, and deployed to Chernarus with a U.S. Marine Corps unit that was running missions near Elektro. His embedded engineering team was testing a newer and more powerful flashbang to use on infected. One of the prototype grenades he worked on accidentally exploded and led to him being injured. The Marine unit he was in received orders to pull out of the region. One of the crew members of the UH-1Y that was evacuating his group was infected and turned shortly after take-off. During that chaos on the helo some passengers bailed out, Harry was flung out over the sea as the helo started to go out of control.
Harry woke up in a strange place with nothing on him, and everything is written in a language he cannot understand.
That accident would cause him to have issues for the rest of his life. He's not sure who he is now. He's not sure if his unit brought the apocalypse. Sometimes he thinks the government is after him because of whatever he worked on in the past, even though he can't remember what he did. Having never been able to shake off the feeling of being watched, he looks towards the sky and doesn’t stay in one place for very long. With a fragmented mind, he's not sure about his past, and doesn’t have the capacity for trusting his memories of people.
