Soul Blade is regular fighting game with acceptable voice acting, interesting storyline, and tight fighting mechanics.
Music is fantastic in every way. Voice acting isn't too bad and could be better. Soul Blade has a great score in the music category. That is possibly my favorite part in every Soul Calibur- related game, the music is always wonderful.
What I think hurts Soul Blade is the lack of unlockables. It is an arcade fighting game, but I think they should have added more modes other than the map adventure mode. It isn't that great, but it keeps things going, I guess. You can unlock costumes and such, so that's a plus.
There isn't too much to Soul Blade but it is a fun game, and you can find it cheap over the internet, so it is worth a purchase and/or a try.
