Action or Stealth...You decide.
The graphics in Hitman: Bloodmoney are lovely, considering the release date. I was very impressed at the time.
The gameplay is excellent. Regardless of the way you play the game, you should have a good time with it. Being stealthy feels more rewarding in the end, especially because you are rated as a hitman at the end of each level, but you can still finish the game if you choose to be a maniac and kill everyone, which is a reason I find the Hitman series to be excellent. This game instantly doubles it's replayability.
Sound is on par with the rest of the game. The ambient noise is fine, the voicework is fine, and music is appropriate.
Overall, it's an excellent game that shouldn't be missed by stealth fans. Especially stealth fans that tire of the tedium that is any Splinter Cell game. I'm a Metal Gear Solid man myself, and the Hitman series is just a couple of rating points short of that series in my opinion.(which is a good thing!)
