Planet Xbox 360 writes: "Dark Sector is a unique game that will catch a gamer's interest for its violence and implementation of its weapon, the glaive. The glaive unleashes a tremendous amount of bloodshed throughout the course of the game through decapitations, limbs being cut off and torsos being ripped in half. If that doesn't catch their interest, then perhaps the beautiful graphics will.
Right up there with Ninja Gaiden, the action is brutal. If Dark Sector was to come out in the early '90s, this would have been one of the select few to be protested by parents, such as Mortal Kombat was. Having heads fly off, while blood is squirting against the walls, Dark Sector isn't kind towards children. Definitely aimed at mature audiences, this isn't for the faint mind."
