Sound- 9 out of 10- The sound in this game is the best in any game! The anoucer makes many funny comments. And there are also many other sounds like, bombs exploding, clicks when you pick up a item, etc., etc.
Replay Value- 9 out of 10- With the posiblitly of making more stages, (hidden option) this game has lots of Replay Value. Not only that the game comes with many stages of its own.
Overall- 9 out of 10- This is a wonderful game for anyone that loves non-stop action, (like me). The only downside is that you have to have a lot of hardrive space to run it, and you have to have a monster machine.
