One unique feature of Sin is its targeting system. In other words, shoot a bad guy in the leg, and he will behave like a person who was just shot in the leg. There are a wide variety of reaction shots when enemies get hit and when they die, and you'll never get tired of seeing them. Although head shots are fatal, it'll still take several machine-gun bullets to the face to drop even the lowliest of bad guys. Still, the targeting system adds a new wrinkle to the game, and it helps, especially when the overall weakness of the weapons is factored in.
Sin has a lot of attitude, but much of it seems misplaced.
Also, Blade's one-liners, for the most part, are pathetic. So far, so good. Sin is an effective game. The action is fast, the graphics are good, the levels are nice, and there's enough plot to keep you satisfied. The attitude doesn't work, but the game deserves some credit for trying.
