He used to live in Scotland until he emigrated to Romania.
Campbell kidnapped the daughter of a wealthy Romanian man. What he did to her, if anything, is unknown. However, at some point he handed her over to his younger brother, Malcolm Sturrock, who tortured, killed, and mutilated her in a bizarre ritual. Campbell was accused of the kidnapping. Although the evidence against him was overwhelming, his lawyer, Andrei Puscus, beat the case with a combination of legal technicalities and illegal bribery. In celebration, Campbell throws a BDSM fetish party at his slaughterhouse.
The young woman's father contacts the ICA, and 47 is given the contract. His assignment is to rescue the daughter from the slaughterhouse if she is still alive (and bring back proof of her death if not), and then to assassinate Campbell Sturrock and Andrei Puscus. Oddly, despite being revealed as the actual killer, Malcom is never a target. Sturrock is found in a living quarters on the second floor, where he lays in bed with two leather-clad prostitutes and is brought entire roasted chickens many times per day.
He is bald white male. He is morbidly obese and wears a red shirt, thong, and black nail polish. He also wears black shoes and grey socks.
It is known he has a very gluttonous personality, as can be seen from the fact that he likes to eat meat (especially chicken) a lot. He apparently prefers to eat alone; if he is brought food, he will tell the two prostitutes lying with him on his bed to leave. If he sees through 47's disguise he will panic and call for his guards.
- He is so morbidly obese that he needs a wheelchair in order to move around. While he can't actually be seen in it during the level, the chair can be found in the slaughterhouse near his room.
- He may be a reference to the character "Fat Bastard" from Austin Powers, as they are both Scottish and both morbidly obese.
- He's the fattest character in the series so far.
- He shares many similarities with Charlie Sidjan from Hitman 2: Silent Assassin : both are overweight, are surrounded by girls, and they also stay sitting in their private quarters instead of fleeing.
- He looks almost completely similar to Zhun from The Lee Hong Assassination, who guards Lee Hong.
