In its report, the Board describe Dark Sector as a "violent and sometimes gruesome game with a sinister storyline and ominous outcome. The violence and aggression inflicted upon the protagonist is of a high level, naturalistic and not stylised at all."

While the Board notes that the violence in the game takes place in the context of Hayden's mission to "defeat a scientist that has infected people with a mutant virus," the report spends several paragraphs detailing the most excessive examples of that violence, leading to the decision that its impact "exceeds strong and as such cannot be accomplished in a MA15+ classification."
