Brandon McEvoy is a curious person. Not much is known about him prior to the outbreak. He had a family in California and was on a flight to Kiev when the Outbreak started to happen. Fearing for his safety, he fled south through the Ukraine until he ended up in Chernarus. Along the way he had several encounters with the local people, most of which were not the friendliest and made Brandon very cautious about his surroundings and the people he encountered.
After his arrival in Chernarus, he met Caleb Gallagher who introduced him to the surroundings and the local populous. Reluctantly, Brandon decided to join Caleb's group of friends for the benefit of keeping himself safe.
