CHAPTER 1: The Courtesy Call

Opening & Puzzle 01

 


Opening of the Game and Puzzle 01

 

The game will open with you in your room and you'll be greeted to a quick introduction to the very basics of moving and looking and then put right back to sleep.

You'll quickly be re-awakened to a destroyed room and introduced to your guide in Portal 2, Wheatley. I just want to say this right away, do yourself a favor and listen to everything Wheatley says. He is HILARIOUS. Wheatley will move your room to a new area and you'll be on your way to starting the game.

ACHIEVEMENT TIME:
Wake Up Call -- 5 -- Survive the manual override

You'll get Wake Up Call just for getting started in the game. Work your way into the first puzzle area. This is a very basic intro area. Simply push the button on the right, then go back through the ORANGE portal to enter the room with the Cube. Pick up the Cube and move back through the BLUE portal to get back into the main room.

Drop the Cube and press the left switch. Now grab your Cube again and re-enter the ORANGE portal. This will move you through the BLUE portal that is now on the left side. Place the Cube on the switch and then back to the main middle area one more time. Now click the far back middle button and through the ORANGE portal one final time and you are at the exit. 1 Puzzle down.

Puzzle 02 & 03

 


Puzzle 02 & 03

 

You'll head through the area until you reach the your first Portal Gun. This one only fire BLUE portals but luckily someones already placed all the ORANGE portals you need. Only certain walls can have a portal placed on them, namely the cream colored walls that are right below you. So fire a BLUE portal on the wall and jump through.

Head up the broken down walkway and you'll come to a large open area. You can see the ORANGE portal already placed on the far side so just place your BLUE on your side and you're past the gap.

Now you can see the Exit on the side over another gap. This time throw your BLUE to the far side with the Exit and then walk through the ORANGE to get to the exit.

ACHIEVEMENT TIME:
Drop Box
-- 20 -- Place a cube on a button without touching the cube

As you come through the door to the next area RUN forward to the pit on the right and aim straight down and throw a BLUE portal down ASAP. As the Cube falls it will go right through your hole and onto the button getting you the achievement. If you miss it, reload and try again. This is the BEST place to get this achievement period. Then just walk out the next Exit.

Puzzle 04

 


Puzzle 04

 

First throw out a BLUE portal and walk through to get on the top small platform. Then throw a new BLUE portal to the far small platform with the Cube. Walk through the ORANGE to get over to that side. Grab the Cube and drop down and place it on one of the switches.

Now look down the far back pit. Throw a BLUE portal under the cube and it will drop through the ORANGE. Place a new BLUE on your level and walk through to get the Cube and place it on the final switch and move on.

In the Exit room drop a BLUE portal on the ground and it will drop you from the ceiling and onto the glass lowering it down. At the top of the glass ramp take a hard right to see the first of Rattmann's dens. No achievements yet but its a nice hidden area to look over. Then continue on to the next room.

Puzzle 05

 


Puzzle 05

 

Just to get into the room place a BLUE portal on the ground and you'll drop into the main room. Hit the switch and then move towards the water. Look to the far right and there is a small platform that now has a Cube on it. Place a BLUE underneath it to get it to drop back behind you in the main room. Go grab the Cube and place it on the switch.

This raises the ramp near the exit. Walk up there to the next set of switches. The left switch drops another Cube. The problem is it gets thrown into the water and destroyed immediately. So right after hitting the left switch, you need to hit the right to get the wall to raise to stop the Cube in the main area. You can do this as often as you need until you get it right. Then back down the ramp and grab the Cube and place it on the second switch to open the door.

Puzzle 06

 


Puzzle 06 - Part 1

 

Place a BLUE portal on the wall to get into the room. Then go to the edge of the pit and look down. Place a BLUE portal at the bottom and fall into it flinging you to the far exit side. Now peak into the glass enclosure and place a BLUE portal underneath it and it will fall into the pit. It may launch to you automatically. If you have to go get it just grab and fling it with you to the exit. Place it on the switch and that's the end of room.

 


Puzzle 06 - Part 2

 

In the next room place a BLUE portal on the angle wall section to the left and then jump through the pre-placed ORANGE portal that is on the bottom of the pit and fling yourself to the far side. Grab the Cube and drop down 2 levels and place it on the far platform by the door.

Now move the BLUE portal to the far top left on the opposite of the angled wall. Then drop once again through the ORANGE portal in the pit and that will fling you to the exit. Pick up the Cube and place it on the switch around the broken glass.

Drop through the ORANGE one last time to fling yourself to the high exit.

CHAPTER 4: The Surprise

Puzzle 18


Puzzle 18

When you come out into the puzzle chamber you'll be looking at a light bridge pointing to the ceiling. Put a ORANGE portal on the far back right and a BLUE underneath yourself so that you can jump over there. Now we need to place a ORANGE on the top of the Light Bridge and a BLUE on the top of the far left ceiling. This is to create a wall for when the Cube falls. Now hit the button and if you placed the portals right the Cube will hit the wall and land into the main area somewhere.

Place a ORANGE on the far wall by the cubes and a BLUE near you and travel back to the starting side. Watch out for the turret and grab one of the cubes. If its traveled too far to get safely simply put a portal underneath it and one near you to bring it you you. With the cube in hand go to the far back side near the entrance. Again, use portals to move if you have to stay away from the turret. First use the Cube to redirect the beam into the turret and destroy it and then redirect the beam through the two right relays.

Now go grab the other Cube and place it at the far end to redirect the beam one last time into the last relay. Finally put a ORANGE on the top of the bridge and a BLUE to get you over to the Exit.

Puzzle 19


Puzzle 19

So we have a LOT of relays to light up in this puzzle. Start by looking to the high right and you'll see a Cube up on a single platform with a portalable ceiling. Throw an ORANGE up there and the drop down and put a BLUE on the floor and drop through getting the Cube.

Now we need to take the the Cube to the back right from the perspective of starting the level. So place a ORANGE up there and drop through the BLUE with the Cube. Now line up the beam to the first relay across the way.

Now we have to fling the next Cube, which is located right on the ground floor, over to this first relay area. Leave the BLUE on the ground and place the ORANGE in the far straight middle above a Faith Plate. Drop the Cube into the BLUE and then look hard right and place a ORANGE so that the Cube will fling over to the first relay area. Repeat the process to get yourself over there also. Now line up the Cube with the next relay which is located in the starting area.

Drop down again and we are going to do another double move fling to get the final Cube which is high to the right of the starting area from our current point of view. So leave the BLUE and again place the ORANGE over the Faith Plate. As you come back through the BLUE place a new ORANGE on the top right corner so that it flings you into the Cube.

Put a ORANGE on the ceiling at the starting area and take the Cube with you to and redirect it to blow up all the turrets at the Exit and then aim it at the receptacle.

Now one final fling from the ORANGE above the Faith Plate to a ORANGE on the top right wall and you'll be at the Exit.

Puzzle 20


Puzzle 20

This is a small room where you need to use Redirection Cube and Portals to light up 3 receptacles from 3 beams.

Start by placing a ORANGE portal on the wall where the far left beam hits the wall. Now place the BLUE on the small column in front of the 3 receptacles and that will light up number 1.

Go grab the Cube that is currently reflecting a beam and place it in the stream of the next beam to go through the ORANGE and hit another receptacle.

Finally grab the last CUBE and redirect the stream that is going down from the ceiling to the ORANGE and that will hit the last receptacle.

After doing that follow Wheatley to a small room with some turrets. Take them out and then portal your way past the room by using a small opening on the panels to see a far portable wall. Then just follow the walkway to end the chapter.



   




CHAPTER 5: The Escape

The Turret Lines


Turret Lines

The door won't quite open all the way at the start of the area so portal on your side and portal on the far side equals moving on.

Continue along the path listening to Wheatley until you get to a turret construction line. Don't go down the stairs, instead go left and jump over the to the construction line.

Continue along the line dodging some moving panels and the lasers that are creating new turrets to shoot bullets at you.

You'll get to a series of tubes that are moving Cubes. At this point look up and there will be a portalable area behind a railing. So ORANGE and BLUE your way up there. Now you are going to be going back and forth across the gap as Wheatley shows you where the next portables walls area.

Continue around to a turret test area. Put a ORANGE at the end of the hall and then a BLUE inside the room to drop in behind the protective wall. Wait for a defective turret to come by and then place a new ORANGE on the far safe area and a BLUE on the wall the turrets are aiming at (which is why we wait for a defective one to come) and walk through to safety.

ACHIEVEMENT TIME:

CHAPTER 7: The Reunion

Beta Puzzle 1


Beta Puzzle 1

As we come into the room we want to get to the high left. So place a ORANGE on the ceiling above it and a BLUE on the ground floor and walk on trough. BEFORE hitting the button place a BLUE beneath the pipe and a ORANGE to the starting area low so that when you push the button the Propulsion Gel makes a long path. Now just drop down and run forward on the Gel to get to the far side.

Place a BLUE on the next target just around the corner to the left. Now place a ORANGE above the button area. Walk through and move the ORANGE to below the pipe again and push the button. Now the far area will be coated. Run over the both tracks of Gel.

Now place a BLUE inside with the Cube and a ORANGE on the outside and walk in and get the Cube. Now move the BLUE to the previous section and walk through with the Cube to get back there. Now one more BLUE all the way back and take the portal and place it on the switch. That will raise the ramp and now you can run to the Exit area.

Place a ORANGE so that it is across from the button. Now back to the start and run from the top of the ramp through the BLUE and hit the Button up high. Now you can exit.

ACHIEVEMENT TIME:
Portrait of a Lady -- 10 -- Find a hidden portrait

Look out and place a BLUE on the middle of the column. Then a ORANGE under where the gel will fall. Hit the button and coat the area in Propulsion Gel. Now look up and move the BLUE to the one ceiling tile, place a the ORANGE under the Repulsion and hit that button. Now run jump to the center column.

Go around the other side and place a BLUE down low and a ORANGE up high and move out onto the top catwalk. Place a BLUE as high as you can on here and then a BLUE back at the start and go through. Now move the BLUE to the center of the column so that when you hit it you will fling out the far side.

Beta Puzzle 3


Beta Puzzle 3

Move through the area until you get to the main puzzle area. ORANGE under the Blue Gel and then place the BLUE on the far top right angled piece. Now move the BLUE to the Propulsion Gel and move the ORANGE to the below the angle to coat the flat part. Now move through.

Keep the ORANGE on the flat bottom but put the BLUE on the top angled and run through from the far side to fling over to a new area.

You can just see it from here but put a ORANGE on the floor of the far left area and a BLUE under the Repulsion Gel. Pick up the Cube and drop down a level and then portal over the that left area and place the Cube on the switch to rotate the plate. Now portal back to the main area and look to the high left. Place a ORANGE portal up there behind the angled piece and then the BLUE on the Propulsion Gel to coat the ramp. Now get yourself back to the Propulsion Runway you made at the beginning. Look up to the left and replace the BLUE up by the angled piece and a ORANGE down below and run through to the Exit.

ACHIEVEMENT TIME:
Stranger Than Friction
-- 15 -- Master the Propulsion Gel

You get this achievement for finishing the puzzle.

Gamma Entrance


Gamma Entrance

Just keep moving through the areas using some very basic portals to get from your low location to some high locations until you get to a control room. Throw all 3 switches and then to keep from getting smashed throw a portal after the catwalk and one by you to get through.

So this new White Gel that is covering everything allows you to place portals on previously non-portal walls. Start by placing a BLUE on the ground in the white and the ORANGE up high on the broken catwalk. Now jump into the Repulsion Gel to get to the other side.

Now this top room is covered in Propulsion Gel is run past the smashing bits to get to the other side and move on to the Exit.

Gamma Puzzle 1


Gamma Puzzle 1

So there is a stream of White Gel spewing everywhere. Where you want to get it is past the mesh fence area on the right. Put a BLUE under the Gel and a ORANGE just everywhere until that side is covered and move your way over there. OK now that you are on the other side you need to get the White Gel to move up between the two columns by moving the ORANGE portal back and forth until it coats the right top. Then portal yourself up to the top.

Place a BLUE on the angled piece to your bottom left and then fall off the top and ORANGE beneath you to fling over to the Exit.

ACHIEVEMENT TIME:
White Out
-- 15 -- Complete the first Conversion Gel test

Elevator Shaft


Elevator Shaft

So this is a large elevator shaft filled with white walls. We want to cut off as much as we can so zoom into the highest point you can see and place your portal. Then one by you and walk on through. Keep moving up until you reach the actual elevator car. Place a BLUE inside the elevator car and then fall off to place a ORANGE before you go splat. This will fling you up  to the top point. Place a BLUE on the angled piece and drop back down to the ORANGE below to get to the Exit.

Open Spaces


Open Spaces

First off place a ORANGE up high on one of the columns and a BLUE on the floor and drop on up. Look up to the top right and fire a ORANGE on the angled piece above the door and then drop BLUE into the floor to fling over.

Now we need to keep the one on the angled piece and put a BLUE under the Repulsion Gel to coat the top angled piece and do another drop from distance to the floor and through a quickly placed BLUE to launch into the Gel and back higher.

Now place a ORANGE on the ground at this new high area and do another drop. As you come out this top ORANGE straight up, fling a BLUE into the even higher area to land in there. From here you can just walk over into the Exit.

Gamma Puzzle 2


Gamma Puzzle 2

First up a BLUE under the While (Conversion) Gel and then the ORANGE on the ceiling at the far side to cover that wall in Gel. Then put the BLUE on the bottom of the column and the ORANGE under the Propulsion Gel. Move the BLUE back to the top angled part and run, then jump into the ORANGE and up out of the BLUE.

At the back of this top area put a BLUE on the bottom and the ORANGE under the White Gel to get the top pipe coated. Then Move the ORANGE to the top and the BLUE to the Repulsion Gel to make a Blue floor and run through the runway again.

Pipes EVERYWHERE


The Pipe Area

As you come to a area with White Gel falling down throw a ORANGE put through the mesh to where the Gel is coming from and the BLUE on the ground and walk on through. Walk into the central pipe area and throw the ORANGE up on the angled piece behind the mesh. This will start coating the area with White Gel. Now that the whole place is coated throw a ORANGE up to the highest area you can and go through. The top is covered but of course there is a white area to drop a portal on so you can go through.

In this large area there is a white wall below a light high up. Then of course there is a place down below for you to go through. Go to the opening on the catwalk and look down. White flooring. Time for a fling. Look to the top right and place a BLUE there, then drop down and put a ORANGE underneath you. Hit the hatch override button and a platform will lower. Simply drop down and go up the stairs to exit the area.

Now put the Force Field across the face of the Monitor so and Fling yourself with the Cube up hitting the field so that you land on the catwalk. Now move the BLUE down into the Turret area to cover yourself. Drop down the back area with the Cube, careful not to hit the field or the Cube goes bye bye, and place it on the switch. Then portal out.

Place the field across the monitor again and Faith Plate up there and Exit.

Wheatley Puzzle 11


Puzzle 11

As always with the Wheatley puzzles you need to fire a BLUE at the stream. Now fire an ORANGE at the floor square and rise yourself to the ceiling. Look for a small square on the wall and fire the BLUE there so you drop into the ORANGE and are flung across to the Cube.

Drop down with the Cube and take it all the way to the lowest level and use the Cube to block the beam. Then portla your way back to the main level.

Now place a ORANGE on the angled piece by the Monitor and the BLUE on the angled piece in front of the Faith Plate and launch yourself through.

TV #7 - Grab the redirection Cube and take it all the way down to the lowest level with the beam. Redirect the beam to the wall and then put a BLUE portal at the beam's end. Now get back to the main floor and put the ORANGE put at the Monitor's level. You may need to tweak positioning at the lowest level until it hits the Monitor and destroys it.

Once the Monitor is destroyed move the Cube onto the square below the switch on the main floor area and then put the BLUE opposite the receptacle on the ground in the back and redirect the beam so that it hits the receptacle. Go stand on the platform below the Exit and move the BLUE so the beam doesn't hit the target anymore. Then put the BLUE under the redirect so that it falls out and the stream starts again. Then put the BLUE under the stream and the ORANGE under the Cube so it raises and hits the switch.

Move to the back platform and cut the stream to drop the Cube and raise yourself to the Exit.

Wheatley Puzzle 12


Puzzle 12

So this puzzle is all about starting and stopping the beam. Put a ORANGE at the place the beam hits the wall. Then put the BLUE on the wall in the starting area across from the receptacle. This will move the platform. When the platform is at the far left side, remove a portal so the platform stops. Then portal yourself over to the platform.

Re-establish the  link until you hit the wall and part of the platform is through. Then move the ORANGE to the top middle to hit the other receptacle that opens the wall. Now move over the the other half past the wall and connect the lower receptacle again by moving the ORANGE.

At the end drop down and move the platform all the way back to the other side and hit the button to drop a Cube. Now portal yourself over to the platform with the Cube.

TV #8 - Move the Cube and yourself back above the button. Move the ORANGE to the square that is on your level on the left so that a beam is coming at you and you can use the redirect to hit the Monitor.

Then angle the beam to the receptacle on the opening area wall. Portal over and re-establish the beam so the the Exit opens. Jump into the tunnel and Wheatley will give you a quick tour.

Wheatley Puzzle 15


Puzzle 15

Hit the button and a Cube will fall on the the glass ledge. Step on the Switch and the tunnel will start flowing. ORANGE on the top and then BLUE on the left to push the Cube to the right. Move the BLUE to under the platform on the far side so the Cube falls into the tunnel and comes back to you. Now replace yourself on the switch with the Cube.

TV #9 - Time for another fling. Put the BLUE on the ceiling and the ORANGE on the floor in front of the Monitor. When you get to the height of the ceiling, move the BLUE to across the Monitor and drop back into the ORANGE and fling across to destroy the Monitor.

Grab the Cube and move to the small hole on the back wall. Portal in and place the Cube on this new switch and then leave back to the main area.

In the main area again step on the switch to make the tunnel work. BLUE on the roof and ORANGE on the back square so that the Propulsion Gel is brought into the tunnel. Wait until it is over the entire area step off the switch so that it falls down and covers the entire path and the ramp.

Then back into the small area to get the Cube and place it back on the main outside switch. Place a ORANGE on the ceiling and then look past the ramp to the far right and place a BLUE so that the tunnel moves from right to left across the middle. Now run up the full length of the ramp and into the tunnel and to the Exit.

ACHIEVEMENT TIME:

Wheatley Puzzle 16


Puzzle 16

So Wheatley has lost it. The chamber is ripped apart in front of you but there is White Gel on your floor and the far ceiling so portal over to the entrance.

Move yourself to the far side with the button. Put a ORANGE at the end of the tunnel, then the BLUE in the back behind the pipe. Hit the button and Repulsion Gel will fill the tube. Move the BLUE right away so that the Repulsion falls on the small front area on the bottom where you are.

Redo the whole thing again only this time use the Repulsion Gel to jump into the stream ahead of the Repulsion Gel. Now drop out at the starting area and get on the Switch. This will reverse the stream. Wait for it to get back to the main section of the tunnel.

Now get off the switch and quickly move the BLUE to the back section where the turrets are. Now SAVE! You need to move the BLUE so that the Gel falls and hits 2 of the 3 turrets. We need one left to destroy the Monitor.

 TV #10 - This is a little tricky. Place the ORANGE at the end of the tunnel but do it to one side so that the tunnel doesn't actually go through. Put the BLUE on the ground and drop into the tunnel. Now look to the far right and put the BLUE over there, then move the ORANGE to the middle so that you actually move on now. Then drop out the tunnel and quickly grab the Turret. Take it out to the main area and put it down to fire on the Monitor.

ACHIEVEMENT TIME:
Smash TV
-- 75 -- Break 11 test chamber monitors

If you've done them all correctly the achievement will pop.

Now hit the button it will angle a wall piece in the main area. Put the BLUE on the end of the tunnel and a ORANGE beneath you to rise you to the ceiling. Then move the BLUE to the angled wall piece and it will fling you over to the Exit.

Continue along the path until you get to the end of the catwalk. Move a BLUE portal to the top highest wall square and then jump off and place the ORANGE on the ground to fling on over.

Wheatley will miss you with another trap so just portal around it and move on.


Turrets

 


Lots of Turrets

 

With all the damage Wheatley has done you can't even get into the next puzzle on the catwalk. So Portal in and you'll fall right into the middle of a large number of defective turrets. Just walk out the door and drop on to the catwalk below.

Continue forward and you will come to a large group of turrets. Creep forward and place a ORANGE at the end of the tunnel. Then place BLUE one after the other behind the turrets to push them out into oblivion. Then jump into the stream to take you to the far area. Jump out before going into the grinder FYI.

Place the portals in this next room so that you can ride the stream out the door. Then when Wheatley tries to smash you move the portal to the lower white to travel backwards away from the smashing.

When you get to the big area with all the turrets throw a ORANGE up to the ceiling to your left and a BLUE on the column right behind you. Stand on the switch and turn around and place a BLUE under the Gel. Then place one high on the right to coat and destroy all the turrets. Then portal over to the Faith Plate by the pipe top finish the are.

Bombs

 


Bombs

 

When you get to the room with the button and the broken glass put a BLUE portal under the pipe and a ORANGE on the room on the wall with the glass. Hit the button and bombs will fall through the BLUE, out the ORANGE, and hit the White Gel pipe. Move the ORANGE to the floor and drop out to the catwalk.

Walk out onto the conveyor belt. Wheatley will start it up going the wrong direction so jump to the next catwalk. Drop a ORANGE beneath the pipes to the right and the BLUE under the Propulsion Pipe and hit the button for some more bomb action. Now move the ORANGE to the back of the conveyor belt to coat the belt and then run the length of the conveyor to get to the far side.

In the next room simply place the ORANGE at the back of the hallway to coat the area in Propulsion Gel. Then put the BLUE under the stream and run down the hall and get propelled into the stream. Drop out of the stream at the end and it's time to end this.

Wheatley

 


Wheatley

 

This final battle is actually very easy.

STAGE 1: First off run over to the White Conversion Gel pipe and wait for Wheatley to throw a bomb and blow the pipe open. Now place a BLUE on any of the high wall pieces and a ORANGE right at your feet. Wheatley will throw a bomb and it will hit him in the head. Now move the BLUE to the right wall piece by the catwalk. Portal up and grab the new Core and drop down and insert in into Wheatley.

STAGE 2: Now place the BLUE under Wheatley and a ORANGE at your feet. You'll hit him from the bottom. You'll then need to portal back to the catwalk and jump and use the Repulsion Gel to leap up and grab the next core. Then use the small spot of Repulsion Gel on the ground to place it on Wheatley.

STAGE 3: This time to need to make sure that the high ORANGE portal is behind Wheatley as he has protected his top and bottom at the front. Some Propulsion Gel will spew out all over the floor. Place the ORANGE at the back of the wall and the BLUE on the floor right next to it. Run through the ORANGE and into the air to get the final core.

A small fence area will open. Place a ORANGE in there on the ceiling and a BLUE under Wheatley and portal through. The ceiling will fall open and place the ORANGE ON THE MOON. Yes you heard me. Then just watch and enjoy the ending.

ACHIEVEMENT TIME:
Lunacy -- 20 -- That just happened
