English-born with an unmistakable accent, Sunshine is a modern adventurer, seeking danger and fortune. Before it was evident that a zombie infection was the cause of the chaos in Chernarus he had plotted a course to the region. Back then, he had taken a chance; he assumed that the chaos would indeed worsen. His objective was to arrive in-country early enough so that he might get the chance to procure some valuable items during the confusion that was to come before anyone else. At the very least he would maybe make a few valuable contacts that might lead him onto his next adventure.
He entered the country on a fake British passport - as Enoch Whittaker. A consultant in the construction industry with supposed expertise on the particulars of Chernarus regulations. This false identity had never enough time to be put to the test by local government as shortly after he entered the country, the apocalypse had arrived.
He's now known by his alias: Sunshine.
He is a man of no professional military background and could be better described as a drifter, a fortune hunter. He has the skills to survive - and the great luck of immunity to the infection, but his real talents (which are vague and hardly quantifiable) are his unusual charisma and uncanny snout for adventure. He has very little time for politics and friends but his persistent and eccentric character have served him well in making contacts he just about trusts. His remaining time in Chernarus will be spent surviving; not that so he might live another day, but so that he might get rich, so that he might get that grand adventure he seeks. He aims to cosy up with the factions sprouting up and find something valuable, something really worth his time.
The particulars of the outbreak, the science behind it, where it came from, who did what and who was in the wrong are no concern to him. He came here on a scent of fortune. He's certainly no crook, and can generally be considered an honourable man, but he really doesn't care about the fate of Chernarus or it denizens. He certainly has no qualms about his main activity which is tantamount to looting.
You can typically expect to find Sunshine scavenging for whatever treasures he hopes to find.
