Disappointing squandered potential
Dark Sector didn't strike me as a game that contained much substance to it. It felt like a game that developed a unique element to it (the boomerang style glaive, and the powers associated with it), and combined it to a relatively tried and true mechanic (namely third person cover shooter) and put it together to make a game. Unfortunately beyond that foundation, and that's really all that is, a foundation, the makers completely failed to construct a compelling video game from this.
The game has very little in the way of story, and as such comes off as a set of disparate levels where you go from Point A to Point B killing everything in your path until it ends. With little to no context behind anything you do the games limited palette of activities is exposed and the game becomes repetitive and uninspired very quickly. It is not without admirable elements, however it is the significant squandering of the potential that helps make the let down that is this game, feel even greater.
The games positive qualities are nice looking graphics, and some well constructed boss battles in the traditional pattern recognition mold. However it does nothing to stand out in a sea of video games to warrant picking it up and playing it. The only reason I played it was because a friend of mine gave it to me. I kind of wish he hadn't.
Actually the one reason, aside from a sense of finishing what I started, that compelled me to play through, was the relative generous nature of the achievements. Without being cheap the achievements were relatively easy to obtain and so I welcomed the points.
