2: The Cold Boot - Portal 2
Super easy first puzzle. A real quick room teaching you that if there is a Thermal Discouragement Beam, that you need to point it at the receptacle. So ORANGE at the base where the beam hits the floor and then BLUE on the ceiling above the receptacle while you are standing on the platform below the Exit and the room is done.
Undiscouraged -- 10 -- Complete the first Thermal Discouragement Beam test.
You'll get this achievement on completing the room.
Jump over the beam and head to the back left to a broken up room with a Cube in it. Place a ORANGE beneath the Cube and a BLUE out in the main area to get the Redirection Cube accessible. Pick up the Redirection Cube and place it in the beam so that the beam is redirected to the receptacle. Then take the ramp to the Exit.
Place a BLUE up on the surface and a ORANGE underneath the Cube to bring it up to you. Place the Cube on the switch and move on.
Place the ORANGE down with you and the BLUE up on the platform with the Redirect Cube. Walk through the ORANGE and grab the Cube. Place a BLUE on the right where the beam hit the wall and then the ORANGE on the ground where you are to send the beam up to the receptacle in the ceiling. Now grab the Cube and jump over to the high platform and redirect the beam to the next receptacle.
There is a Rattmann den down and to the left if you want to see it. You'll have to replace all the portals to move on but it is a unique hidden item in the game.
ORANGE at where the beam hits the wall and then BLUE in the middle of the back to get the platform moving. When it reaches the far left with the switch, move the ORANGE to kill the beam and place it with the switch. Walk through the BLUE to get to activate the switch and get the Cube and place it on the movable platform and get on there yourself.
Place the ORANGE back with the beam at the wall and ride the platform to the opposite side. Place the Cube on the switch and move on to the next puzzle.
Hit the switch and the Cube will drop on the middle of the level and bounce up and down. Now stand on the Faith Plate and launch yourself through the middle, grabbing the Cube as you go. Place it on the switch and move on.
Place the ORANGE on the back right angle wall, then the BLUE on the other one. Step on the Faith Plate and get flung all over the level until you get to the far platform with the switch.
Final Transmission -- 20 -- Find the hidden signal in one of the Rat Man's dens
Press the switch and the first load of items sent to you is trash. What we need to do is grab the Radio from this stream of trash. It's the Half Circle White object. Press the button again and get the Cube.
Now place a ORANGE on the back right wall where you came in and a BLUE right besides you. Grab the Radio and head on through. Place a BLUE on the right angled wall and the ORANGE on the top left wall in the angled wall area. Now back on the Faith Plates and you'll be flung through that ORANGE into a hidden Rattmann area. Take the Radio to the back of the room for the achievement.
Work your way back to the platform where the Cube is. Place a ORANGE portal on the top of the ceiling on the corner where the switch it. On place a BLUE on the wall in your area and take the Cube through and place on the switch. Back once again to the main platform by jumping over to the Faith Plate with the switch and Exit the puzzle.
After GLaDOS has her fun and destroys the first few Cubes, pick the final one up and block the beam. Stand on the platform that lowers and then put a BLUE under the Cube and a ORANGE on the wall somewhere to clear the beam and raise the platform.
Now put a ORANGE on the first angled wall and a BLUE beneath the Cube to bring it up to this top level. Now place a ORANGE on the far of the 2 angled walls and then drop down into the BLUE you already placed on the floor and fling yourself to the far side and place the Cube on the switch. Now place a ORANGE on the left angled from your current point of view and fall through the BLUE again to get to the absolute top of the puzzle.
Preservation of Mass -- 20 -- Break the rules in Test Chamber 07
Walk into the Exit area but DON'T exit. Put a ORANGE portal inside the area. Go back to the main puzzle area and grab the Cube and then drop back into the BLUE again. Achievement unlocked and move to the elevator.
Look through the small hole in the glass and place a ORANGE portal. Then a BLUE where you are and walk on through. Jump over the beam and hit the switch to drop a Cube. Back through the portals to the starting room and grab the Cube and then back to the room. Take it back through and redirect the beam to the wall unit. Back through to the main room and Exit.
