    NegativeCreep08The video that Pedle linked to does make it a bit clearer that you have to angle the beam on the final jump. Got it the first time I tried that method

    DeathDealingCatThe solution should be updated to use the video Pedle Zelnip linked. Got this first try using the angle method from that video!

    Mr DuckI'm slightly late to the party but can this be done in split-screen CO-OP?

    This challenge takes place in Course 3 Chamber 3. You will use 3 Portals in the first room and 2 Portals in the second room.

    Room 1:

    Portal 1 - Go to the edge of the platform you start on, look straight and slightly down. Fire a Red Portal (There are 3 tiles, aim for the middle one).

    Portal 2 - From where you are, turn 90 degrees left and you should see a wall where the Hard Light surface ends, fire your Yellow portal at this wall (You might have to get a better angle).

    From here, you should be able to walk across the surface, through the portal and get to the switch (Go to it). Have your partner walk across the surface, but not go through the portal until they catch the safety cube (You can hit the button as many times as you want).

    Portal 3 - Once your partner has the safety cube and is through the portal, walk on where the Hard-Light Surface is coming/spawning from (There is a small part of metal you can walk on).

    From there, look up and to the right and you should just barely be able to see the wall above you. Fire your red portal there, and you should then be able to walk through your yellow portal to where the cube needs to be placed.



    Room 2:

    Portal 1 - Once you enter the room, go to the right corner on the platform you are currently on (As far right and as close to the water as you can) and look up . Fire the red portal in the space/line between the 2nd and 3rd tile (From the right).

    Portal 2 - Fire the yellow portal at the wall where the Hard Light Surface ends.


    If you've done it right, you should be able to launch yourself with the catapult and deflect yourself onto the platform (Make sure you move yourself toward the platform after you deflect)..

    Course 3: Hard-Light Surfaces Chamber 3

    This achievement requires perfection. You can only use a total of 5 portals. Have one person only use the portals. You will have to lay 3 portals in the first room. Follow the directions of what portals to use so you don't make a mistake. The first portal () will be place against the wall to the left in the beginning of the course. If you walk up to the edge and look straight, The second portal () you want to place will be on the left wall out in the distance. You will see two rectangles where you can place your portals on. You will want to place your second portal on the farther one, right in the middle so it lines up with where the ball will drop out of.

    Once you have those two portals placed, have the other player walk slowly through the portal so he is halfway through each one. This player will now want to fall on the Hard-Light Bridge below him. He can die as many times as he wants. When he has done that, the other player will want to walk through his portal so he is halfway through as well. He will now was to place his third portal () on the wall where the Hard-Light Bridge is touching. If done correctly you will now be standing on the Hard-Light Bridge. Have the person below who is near the button press the button. The person above will catch the ball and but it in the spot where the ball goes. Make sure you don't walk through the door with the shield until your partner gets there.

    In the next area you will only have 2 portal placements left. The person who is placing the portals, walk towards the Aerial Faith Plate. Now line yourself up with it. Go as far as you can to the right (against the wall) and as close as you can against the water without falling in. Now look straight up and you will see a long rectangle you can place portals on and within that long rectangle are a bunch of rectangle squares. Place a portal () on the second square to the right, right in the middle. Now place your other portal () on the wall the Hard-Light Bridge is touching. Now you will have the Bridge on an angle straight in front of the Aerial faith plate. This next part applies to both people, but the person with the portal placements has to do this first try. The other player can attempt this as much as he wants.

    Line yourself straight with the Aerial Faith Plate. If you look down you will see a line you can line yourself up with. Now do a 90 degree turn to the right. Now you want to move to the left towards the Aerial Faith plate. Right when you touch the Aerial Faith Plate hold forward and you will be launched towards the angled Hard-Light Bridge and bounce towards the door. The achievement will unlock once both people have done this.
