so with the release of crackdown 2 nearing here in the UK, I thought I would go back on the first Crackdown and try and get a few of the achievements that I'm missing, mainly concentrating on the agility orbs and then the hidden orbs. So after jumping around and collecting, I've finally got 498/500 agility orbs.... and I can't find the last 2 ANYWHERE! ARRRRGGGHHHHHHHH! 
 
Hidden Orbs wise, I believe I've collected around about 150-160 so about half way. 
 
apart from the orbs, I've been going back through the game, killing the gang members to finish off the last 2 of the 5 abilities in which for both, I'm currently on 3* for both. 
 
And then comes crackdown 2..... WITH MORE ORBS!!!!!! O.o
