Chapter 2 – Mass and Velocity
Back to Portal 2
Orange places a portal on the white platform on the floor and the other on the white wall on the ledge. Blue goes through and then Orange places the second portal on the wall overlooking the gap. Blue drops through and is sent across the gap to the other side. Repeat for Orange.
In the next room Blue needs to get fired across to the high ledge to the right and Orange to the small ledge to the left. Place a portal on the wall and one on the wall high up to the left next to the lift. Go through the portal. Place a portal on the floor under the lift and one on the wall opposite the high ledge. Blue drops through and is flung across to the ledge.
Orange portals up to the lift, places a portal on the ground and the second on the wall opposite the lower ledge. Drop through to get flung across to the lower ledge. Both players stand on the buttons to drop a ball. Place the ball on the pressure plate to open the exit door.
Just to the right of the button is a small alcove with white roof and floor and a barrier between them. Orange places a portal on the roof and the floor. Blue drops through and gathers up speed as he continually falls through them. Orange presses the red button to fold away the barrier and quickly replaces the portal on roof with a portal on the sloped white ledge. Blue should get flung across the murky water to the other side.
Blue now places portals in the alcove from the other side and the procedure is repeated to get Orange across.
There’s another robot flinger so have Blue place portals on the roof and floor and let Orange drop through them. When Blue has gathered up speed Orange should replace the portal on the roof with a portal on the sloped white platform. Blue should get flung across to the other side and press the red button to drop a ball. Orange must stand on the red button so the ball doesn’t fall into the water. Blue can pick up the ball and run back across.
Orange goes up the steps and Blue passes the ball to Orange. Portal up to the top ledge and place the ball into the pressure plate to open the exit door.
In the first tall room you’ll see two platforms with arrows pointing up and a robot flinger just further on. Have Orange place portals in the robot flinger so Blue can drop through them and gather up speed. Orange replaces portal on the roof with one on the first platform. As Blue is flung up he must press the red button.
Before Blue drops down Orange should place the second portal on the other white platform. Blue will drop down and get flung up to the second red button. Press this one as well and four balls will drop down. Place one of them on the pad near the exit to complete the level.
Orange places a portal on the mark above the bouncy board and the second on the sloped platform. Blue bounces up and across to the ledge. Orange does the same.
In the next room have Orange place a portal on either side of the hanging white platform . Blue should place a portal above the bouncy board and on the sloped platform. Blue bounces through the portals and then through the white hanging platform. Blue replaces the second portal with one on the sloped white platform on the ledge. Orange can now bounce through Blue’s portals to the door. Blue drops through his second portal and gets bounced back to the door as well.
In the next room have Blue place a portal above the bouncer and the second portal on the white platform below the ledge with the cube. Bounce through the portals and retrieve the cube. Drop the cube and Orange should place a portal on the sloped platform and the second underneath where Blue is bouncing. Blue will get flung through the barrier. Pass the cube up to Blue so he can place it on the button. This opens up the wall to reveal a barrier.
Orange flings himself through the new barrier and places two portals on the white walls. Blue flings himself across as well but should now get flung back to the exit. Blue can place portals near the exit and one on the platforms on the floor to let Orange across to the exit as well.
You’ll need to use the bouncer to fling yourself across the platforms to the red button that will release a cube when pressed. Blue places two portals on the sloped platforms on either side of the bouncer and Oranges bounces through. Orange places two more portals on the next two platforms. Blue bounces through and should land on a ledge with the red button. Once pressed the cube will drop and get flung through the portals to the same ledge. Place the cube on the pressure plate to open the door.
Use the portals to fling both robots onto the same ledge. Once one robot is on the ledge he’ll need to replace the second two portals with his own while the first robot goes back and gets flung across.
The next large room has a number of bouncers surrounded by murky water. The red button drops a cube which bounces across to the opposite wall and then drops into the water. Blue will need to stand by the red button while Orange bounces across to the far platform. Orange places two portals on the white walls and bounces back. He’ll end up going through the portals. As he does this Blue presses the red button. Orange must catch the cube while in the air. Place it on the pressure plate to open the exit.
The first room has two large red buttons on the wall above the door and two bouncers. Blue places a portal on the left wall and on the back wall opposite the right button. Orange places a portal on the left wall and on the back wall opposite the left button. Both players should stand on the bouncers at the same time so they hit the buttons together and open the door below.
The next room has a hallway with a laser and a cube on the floor. Blue places portals on the wall opposite the laser and opposite the receptor. When the spiked mashers have finished Blue should run into the hall and direct the laser through the portals while Orange stands on the lift in the corner.
Orange places a portal on the floor beneath the lift and one high on the wall to the left. When the lift is up Orange drops down through the portal and is flung across to the opposite wall where he hits the bouncer which sends him down the hallway into the red button which stops the mashers. Blue can now safely walk through the hallway as well. Make sure to bring the cube with you.
In the next room there’s a bouncer on the floor and a red button on the wall. Place a portal next to the door and one above the bouncer. Drop the cube onto the bouncer and when it hits the button quickly run through the door to the exit.
This is a large open room with a laser in the middle. First you’ll need a cube. Look over the ledge to see a white ledge down below. Orange places a portal on the ledge and one on the wall underneath “01”. Blue places a portal on the wall under “02”. Orange drops through and hits the red button which sends a cube upwards out of the pipe. Shortly afterwards Blue drops through the portal and is flung across so he can grab the cube while it’s in the air. Blue places a portal on the wall so he can get back with the cube.
Blue holds the cube and directs the laser towards the receptor which turns off the giant fan. Place a portal on the wall facing the fan and drop down the portal to be flung across.
Enter the office and wait for Blue to set up the portals so the laser is sent into the storeroom beyond the office room. Orange places a portal where the laser hits and the second portal opposite the Fan Shutdown receptor. When the laser hits it the fan will turn off. Blue can now fling himself across past the fan. Both robots need to pull the switches at the same time to open the door.
Go up the steps to an office room and place the disc into the player to end the level.
