Isaac Clarke

A genuis engineer with the CEC (Concordance Extraction Corporation). Smart, quick witted, clever. Uses his engineering tools as weapons like his plasma cutter that shoots a disk of plasma to cut limbs, and whatnot. Isaac was aboard the Ishimura when these nasty monsters known as Necromorphs took over the base. After a grueling few days, Isaac came out as the only survivor, suffering from PTSD, and paranoid schizophrenia as a result. Aside from that, he's a really great person to talk to... When he's not suffering from his psychosis.
