PAIN

First of all, you will need to open Afterhours, and to do this you will need to activate three switches in Abusement Park. The first one on the right, you can easily identify him by the “i” that lights up above the stone, shoot him, grab him and wait until the red text appears. The second one is in the cave under the “rocket”; to get there you will first have to break the boards. This will require 2-3 shots, you don’t have to grab it to activate it. And the last switch is at the top of the silo, behind the sign.
Abusement: First fly to the bear at the top of the roller coaster, then fly into the silo stolon and “ooch” down onto the road and towards the “fan” which will throw you up again. The “fan” can throw you in any direction, so depending on where it throws you, you try to hit either the “rocket” or the racers. If you hit the rocket first, then fly towards the racers. Once you get to the race track, try to get hit by as many cars as possible, and then "ooch" towards the water slide, this should end with the boats colliding.
Afterhours: This is the hardest part. First of all, blow up the barrel on the silo. Then "ooch" onto the race track and get hit by almost every car there. Then "ooch" the water slides and try to cause mayhem there, by this point you should already have a combo of around 10x. Be prepared that it will take you 10-15 minutes to dial 2 million on this card.
