Dave - thanks man, I wanted to avoid the phaser reece style kind of synth, I feel its been done to death, however a bit of light distortion like you say may help to give it a more grizzly feel - I will give it a go.
Lucid - I wasnt aiming for uber dark, more dirty really....strange comment about video game music, I can't see it myself personally, I wish they did have more dnb in games! The stuff you can get nowadays is pretty good sometimes in games, I personally know a breaks producer (who won Breakspoll + played radio one etc) who wrote music for EA games until recently...so not a bad thing in my opinion, thanks for the comments though.
