Crackdown 2

Requires level 5 agility and (Y) is to activate the Wingsuit. I would suggest practicing with the Wingsuit out of a chopper to get the hang of it before attempting most of these.

As mentioned by https://www.trueachievements.com/HybridPK.htm and confirmed by m0rph3us17 with the addition of the toy box DLC you can use the jet boots to help you, I haven't tried it but i would imagine that this helps a lot since you can basically fly with them if used correctly. If i remember correctly you don't need to buy the DLC to use these just DL the free version.
This video helped me a lot.

When I hit level 5 agility and started flying, I quickly found I had no skill in it, and was pretty sure I wouldn't be getting this achievement... which was true until I discovered the truth.

Not one of the rings actually needs you to be *flying* through them to activate them.

I was able to use the jet boots (which I have belatedly realised are part of the Toybox DLC) to slow hop through every wingman stunt ring; bar one. Only the rings above Agency Tower require a bit of flight to succeed at, where you must give yourself a second or two of flight after every ring to regenerate a little of your jet fuel - all except for the gap between the second to last and last rings.

This gap is too large for you to use the boots alone, the timer will run out (the rings do have a time limit before you get told you've failed and have to try again), yet it doesn't actually matter. Simply do one swoop flight with your wings, and you'll get that final ring.

This is how I got all ten of the rings, so I know it works.

EDIT : An amendment to this solution for those of you who do not have nor want the Toybox DLC - it is still possible that this solution can work for you!

First off, you must go to the Marketplace and download the free preview version of the Toybox DLC (about 144MB I believe) then start up your game. Then simply invite into your game a friend who *has* bought the DLC. Make sure you both spawn at the same location, near a friendly tactical location with weapon's crates nearby, then have your friend go over and exchange his jet boots for whatever grenade is on offer.

Then you swap out yours for the jet boots... and you're good.

As long as you don't:
A) Die,
B) Use the 'Request Weapon Drop' to reequip yourself, or
C) Quit,
you'll keep the jet boots for the rest of your game. In fact, your friend can quit out as soon as the swap is complete and you *still* keep the boots (having done this as the 'friend' in question, I know this works).

Thus a way for this solution to work for everyone, regardless of DLC purchases :)

EDIT 2 : And if you want it, another slightly easier solution than the edit above. Simply get yourself invited into a friend's game - one who has the Toybox DLC - and you'll have access to every weapon and vehicle he has unlocked, including the Jet Boots, the ATV and the Squad Chopper.

One quick tip for a handful of the stunt rings: you do not necessarily need to glide through all of them without touching down lets say you miss it but its within jumping range, you can just jump through them ( if you watch the video, this is possible with the last ring of stunt number 1, 2, 4, and so on with the ones close to the ground) you just have to be quick about it before you fail the stunt ring!
