Hint - Crackdown Token Collecting:
With my agility token count at 495 out of 500, I thought I'd share a couple of tips. This is one of the tougher achievements to get, considering it will take a lot of dedication and exploration. But if you get Crackdown, honestly, this is the only thing that will keep you playing past hour 10.
Order of Density:
The agility orbs are not evenly distributed among the three islands that make up Paradise City. Los Muertos has the bulk, with at least 200 of the 500 orbs. The Volk is second, with Shai-Gen well behind. Don't rush to the other two islands, even after clearing Los Muertos. Stay, run across the rooftops and in the streets (it's often easier to spot orbs looking up than from rooftops in Los Muertos territory). Keep searching. When I got down to just 15 orbs, I was surprised to discover 10 more lying around on the first island.
Agility Orbs are easy to see:
Unlike the hidden orbs, agility orbs are almost always in plain sight. Some are on top of rocks near the water (which make them tougher to see), but all 495 I have found so far are in the open. Often orbs are missed because you aren't looking up and down each side of every building.
Complete all Rooftop Races:
The races take you past a lot of orbs, so do all 14 races to help easy collecting.
When you see an orb, get it:
Quite a few times I was in a rooftop race or fighting a boss and I saw an orb and said, "gotta remember that one." Don't make this mistake. It's easier to divert yourself and get every orb you see. Don't wait until later, because the city is so big and there are so many orbs, you are bound to forget where you saw one orb in the middle of doing something else.
Be Methodical:
I recommend fully exploring the rooftops while taking on the three gangs. By the time you finish off the last boss, you should have around 400 orbs (and 4 stars in your agility skill). Now comes the hard part... start with the third island and break it into sections. Get to a decent height and use the sniper rifle to scan each side of each building. Yes, it's slow going, but it's way too easy to miss one or two orbs. Usually you will find that when you discover one orb, there are two or three more nearby, because you just never came to that specific spot.
Commit or Quit Early:
There are no achievements for getting half the agility orbs or 400 or even 499. It's all or nothing. So before you start doing a hard search, decide if you really want all 500. Because when it gets down to about 20 left, it becomes very difficult and a bit tedious. If it doesn't matter that much to you, don't bother. You have to be persistent to find the final dozen.
