Kind of like if Gears of War and Resident Evil had a baby.
As soon as i started playing it, It looked like Resident evil 5 . but the controls are much like Gears of War. Its a shame that the Campaign is so short because the gameplay is one of the best i have seen. The graphics are that of Gears of War or Resident Evil, With vivid colors, and realistic looking environments. There are'nt a lot of weapons but you can upgrade weapons with modifications you find throughout the levels. Also you can buy weapons in the Black Market with "Rubles" that you find throughout the levels as well.
I loved this game. Its very fun with an interesting storyline. D3 should make more games or make a sequel to DarkSector
