You control multiple characters that each have different skills, and have to determine how to combine their abilities to complete a mission. There are multiple ways to succeed. You can be stealthy, or come out with your six-shooter firing. The main character, Cooper, is my favorite char. Kind of makes me feel like Eastwood as I wipe out the bad guys a few at a time with him, and knock civilians on their arses.
Graphics are excellent.
Kind of like Baldur's Gate or Icewind Dale, you have beautiful backgrounds that are painted, and your characters transverse them. The old west theme is very well done. Lots of color and little slowdown. The FMVs are a nice touch inbetween missions. Sound was above average.
