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. Gunfire and explosions sound real enough, and the voice acting was fair.
Cooper is a bit overdone, otherwise the characters are great.
Not much else to say about the sound. All in all a commandos clone. Unfortunately it doesn't reach its standard. A buy only for hardcore fans with plenty of time. AI of opponents is OK so far.
