To do this cheat you need two people. Both have to be in seperate helicopter. Both people need to fly at equal heights in a beacon laser. Then both people need to fly down at equal height (at least 10 feet under the beacon). So when you kill enemies you get agility with firearms or explosives (depends on the helicopter that you have).
Spawn at the Agency tower. Note: It is recommended that you get your Agent's agility up to level 5 so you can have the Wingsuit. Once you spawn, move to the right and look for a large cylindrical pipe directly in front of the Agency Holding Pens building. It will be very tall, and is the only one that has an opening at the top. Jump down, but be careful; it is a very long drop. Use the Wingsuit's glide ability to slow your descent. You should find yourself in a small cave, in which there is a very large toilet with rubber duckies and beach balls.
Note: This is a random glitch. Get the harpoon gun. Blow up a car and get its tire. Place the tire at a location where you can shoot somebody into it. Note: The target can be civilians, Cell, or Agency but not Freaks. Shoot the person into the tire and it go crazy. If it does not work at first, try again.

Easy Driving Experience
Simply wait until night time and get a car, then just ram into all the freaks! Tip: this works better at what I would say is midnight.
You know how you really want a helicopter but it takes so long to get agility 5, well I have a solution. The requirements are simple, you need driving 4, strength 5 and thats it. So first you have to face the wall on the right of the Agency Tower in the SUV and drive the SUV into the wall. When your'e about to ride on the wall hold down B and keep holding the gas button and when you're up there you got to look at the building that is closest to the helipad and throw the SUV on top of it. Then with the wires next to you jump on them and then on the window seal get on top of the building. Then get as far back as you can then drive the SUV while holding B and just as you are about to fall off let go of B and then you will land on the pad.
Easy Renagade Agility Orbs
Get a helicopter from the Agency Tower and fly high above the Orb (Low enough that you can survive, unless you have the glide suit and can slow down). Jump out and drop down onto the Orb and it will not start moving until you are very close. If you have enough speed you should fly right into it.
Easy Vehicle Stunt Rings
This requires 2 people in an online Co-Op match. One person must get a helicopter from the Agency Tower and the other must get a vehicle (Agency Supercar or Cruiser. Both players should meet at the stunt ring. Equip Mag Grenades and stick one to the bottom of the helicopter and one to the roof of the car. Use the helicopter to fly the car through a stunt ring. Be careful: The mag grenades have a timer on them and will eventually explode.
You can also toss a car with a fellow player inside through a ring.
Press Up to get a quick view of nearby orbs on the mini-map. You can repeat this after a few seconds.
Use the following trick to find all the non-renegade orbs faster. Press Start during game play, then quickly press B, Up and look at your mini-map. It will be zoomed out, and it will also make the orb ping (Up) work in a much greater range. It will show you more orbs around you, and in a bigger area, which will in turn allow you to find the orbs faster as long as they are not renegade orbs.
With an Agility 4 or greater, get a helicopter from the Agency tower and fly it as high as possible. Click and hold the Left Analog-stick to activate its jets to force the mini-map to zoom out as it moves faster. Tap Up to begin scanning for orbs.
Note: This trick requires the Glide ability (level 5 or 6 Agility). Begin gliding and aim at something to hit. When you hit the ground you will roll. You must roll into the object (people, cars, etc.). The object will go flying.
Use the following trick to find a helicopter with weapons. Spawn at the Agency island. Look at the gate to the bridge. Climb up the building to the right of the bridge. Look straight ahead after climbing to see a landing pad with four helicopters on it. Note: Level 5 Agility is required to reach them. Note: The helicopter closer to the Agency tower, and across from that, has missiles. The other two have machine guns.
Use the following trick to find a helicopter with guns. Spawn on the island northeast of the Agency island. Once in the middle of it, climb the highest tower there. When you reach the middle level (with the free standing balconies), you will find a helicopter with no guns.
This cheat requires a second (cooperative) player on Xbox Live. Mount a turret and fire it. As you fire it, have your partner knock you off the turret. When you stand up you'll have infinite ammo -- and grenades.
Mounted Turret Reload
To reload a mounted turret that you took from its stationary post (requires level 3 Strength), just find the post and replace the turret. Pick it up again for fresh ammo.
Press UP on the D-Pad to briefly get a glimpse at the nearby Orbs on your mini-map in the lower left corner. This "Orb-dar" takes a few seconds to recharge before each use.
Orb Locator Exploit
Remember there is a built-in orb locator for all agents in Crackdown 2. All you do is push UP on the D-Pad.
If you want a really good view of where the Orbs are, pause the game. Then unpause the game and immediately push UP on the D-Pad.
The onscreen map briefly has a very nice aerial view when coming back from the pause screen so the Orb detector will pick up more locations.
Quackers Duck Grenade
Begin by recovering the Beacon prototype by claiming the initial two bases, then activate three Absorption units to repair the First Power Network. This will let your agent deploy the Power Station Beacon in the Freak Lair to clear it of enemies.
Go and take over the Cell Tactical Location at the Funland Carnival. Satisfy the kill quota until a support chopper comes to finish the takeover (with the allied soldiers doing the fast-rope). Save (and quit) your game. Boot the game again, reloading that last save, and head back to the Funland Carnival.
One of the "Chuck's Ducks" game stalls has Quacker Bombs. To keep them for future use, just go to a Agency dropsite with them in hand. Easy!
Reach Helicopter Platform With Low Agility
1. Store a "long" vehicle at a drop point, like a ramp truck.
2. Extract to the agency tower building and equip mag grenades and choose the long vehicle.
3. Pull the door off of your vehicle and stick a grenade to the front of your vehicle and the door. If you cant get the door off blow up a grenade on it.
4. Pick up the door, look towards the helipad (to the east of your extraction point) and jump to the platform.
5. Run down the path to the heli pad (making sure that your vehicle is behind you), drop your door and blow it up.
6. Jump and stick a mag grenade to highest part of the bottom of the helipad and the front of your vehicle. This will cause it to hang in the air. Stick a mag grenade to the back of your vehicle and one to the ground. This will cause your vehicle to be pulled to the middle of both points and you will be able to jump onto the vehicle and make your way up to the helipad.
There are orbs on smokestacks that are an extreme pain to get. These can be obtained easily with the help of a helicopter. Get your agility up to level 5 (for the wingsuit) and make sure the Agency Tower is unlocked. Climb the tower to get to a helicopter. Approach smokestacks slowly and hover just above them (your landing gear may deploy but that's ok).
You must have a level 5 in agility before you attempt this. Get a helicopter and fly around Agency Tower until you see a big tube-like thing with no top. Fly over it and get out of your helicopter. Now, use your Wingsuit to fly down the tube. At the bottom is a toilet full of rubber ducks. Oh, and it's huge.
