Thanks :)
 
Using the helicopter is very helpful, it's great that they added a way to see which part of the city you're missing them on.

Nice, I'm at 473/500..the last few ones are a bitch to find. Reminds me of Infamous, with 200 more orbs :P.

I found that last one, yet again I missed one of the easiest ones in the game like I did in the original Crackdown. Only took me 6 days this time, knowing where to look is extremely liberating.
 
Hunting for the agility orbs has always been the most fun part about Crackdown IMO. I love seeing one atop a high building, then going to grab it, then seeing a long line of ones I still have to get and go hunt for them too.
 
I made a vid for the final one:

I will also be making a guide for them too, check out gamersource.weebly.com in a few days! 

Peace.
