Doc - the soldier BACK STORY (READ ME FOR HOW HE GOT IN THIS MESS): Doc is an soldier sent into the lab as an investigator. While he was just an medic, one of his allies dropped and heavy AR. not heading the warnings of all the bodies from his dead (or near dead) allies, he continues into the facility with the AR in his hands, this will (probably) be the last mission he would ever do.
doc is an tank, his ability is an quick heal for health. he has low damage output and his main skill is survival, he is slow, trust me the helmet is more heavy than you would think, he is basic but still has an very unique more cautious play style.
