Crackdown 2

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.
