After playing through once on normal, I'm enjoying my 2nd playthrough on hard because I'm familiar with the controls. It's fun mixing disarms, headshots, and focus mode to mow dudes down and move quicker through it than my first playthrough.
Not the best quality audio, video, or action, but good pace and variety of action. Worth the current used price. Nobody said a bloody action game had to make sense, and at least it wasn't as boring as a CSI game.
