Just get the game.It's that damn good.Seriously.I mean it.
You'll spend the game alternating between two characters:Lucian,the bad ass seeking revenge,and Aaron,the lighthearted apprentice sharpshooter.Oh,and did I mention you get to do a lot of VAMPIRE SLAYING?You'll go through the game collecting elemental beings called "Terrennials" to help you on your quest to defeat the Vampire race,all the while engaging in full 3D space ship sequences with a kind of Astroids feeling to it,only better.You can even collect more weapons for both characters:various swords,lances,etc. for Lucian and solar guns for Aaron.Yes.Solar guns.Aaron gets his energy from the Sun.And Lucian,from the Moon.Don't tell me that's not awesome.
The game's sound effects are pretty solid,with good voice acting (though,Aaron's voice can be a bit annoying at times).But the music in this game is great.All the tracks have a really catchy beat that you'll probably be humming along with throughout the game.
In short,this game has it all:Originality,story,awesome music,and friggin VAMPIRE SLAYING.Just get the game.It's that damn good.Seriously.I mean it.
