22 Portal Strategy

Proceed forward. It is not necessary to use a portal to pass the malfunctioning door, just wait to go through.
Crouch in the right hand corner near the laser wall and aim a blue portal right above the security camera.
Place an orange portal on the wall and proceed through so that you are standing on the security camera.
Jump from the camera onto the next level then shoot an orange portal on the upper side wall through the laser ceiling.
Jump back onto the camera, go through the blue portal, then proceed to the next area.
Shoot a blue portal at the center of the small island in the right hand corner.
Place an orange portal on the wall back towards the entrance and carefully walk through.
From the edge of the island, aim to shoot an orange portal up and to the right at the small wall.
Drop through the blue portal to the upper area then shoot an orange portal at the floor of the pit.
Drop through the orange portal and land at the edge of the laser bridge.
Walk forward and shoot an orange portal through the laser wall.
Drop onto the floor next to the blue portal then carefully fall through it into the next area. CAUTION: Do NOT drop directly into the blue portal.
Shoot a blue portal at the left hand side of the opposite wall as close to the corner as possible.
Walk carefully onto the white edge of the laser floor near the wall, then shoot an orange portal on the wall directly opposite the opening above the button.
Fall through the blue portal onto the button.
Shoot a blue portal onto the wall and very quickly run off the button, through the portal, and shoot a new orange portal through the doors before they close.
Go through the blue portal into the next area then proceed across the bridge.
Shoot a blue portal on the wall next to the cube dispenser button then go back across the bridge and enter the orange portal.
Shoot an orange portal onto the opposite wall above the ledge for the next floor.
Push the button, get a cube, then carry it through the blue portal to the next floor.
Use the cube to block sentry bullets, walk into the alcove, then shoot a blue portal through the energy bridge onto the upper wall behind the glass partition.
Carry the cube back through the orange portal then run across the energy bridge and use it to knock over the sentry gun.
Go back across the energy bridge, drop the cube on the button then go back across the bridge again.
Shoot an orange portal downward onto the opposite wall then proceed back through the blue portal with the cube.
Shoot a blue portal downward onto the opposite wall and proceed through the orange portal with the cube.
Run past the lightning when it is safe then shoot an orange portal down onto the side wall.
Go back through the blue portal with the cube.
Kill or pass the sentry, then go through the door with the cube, but not too far.
Place the cube directly in the center of the doorway so that it can't close all the way then proceed forward.
Turn back towards the entrance and shoot a blue portal at the very top of the wall across from the energy barrier.
Go back through the barricaded doorway and carefully shoot a blue portal through the orange portal, through the energy barrier, and slightly downward onto the opposite wall, then drop backwards through the orange portal before the blue one lands. (If done correctly you should be standing in front of the orange portal staring a sentry gun in the eyeball.)
Go through the orange portal, kill the sentry, then shoot a blue portal onto the opposite wall.
Drop down and shoot an orange portal at your feet as you fall.
Proceed through the disintegration barrier and very quickly jump at an angle towards the three sentry guns. As long as you are quick you should be able to grab and knock them over then proceed to the exit.
