Siliconera: "In Operation Darkness Hitler can repel bullets with psychic powers. Werewolves from Scotland wage war against the Blood Clan, vampires employed by the Nazi army. I'm not sure if Atlus or Success made the decision, but Operation Darkness twists history with caution. Cordelia emphasizes not all Germans are evil. In fact you even meet an honorable German soldier in a tank who isn't crazy about raising the dead. Operation Darkness is careful, well as careful as a game with werewolves holding bazookas can be."
