Course 5 %26ndash;Mobility Gels
To start, one player will need to portal up to the upper platform and press the button there to release the repulsion gel. Once it is on the ground, hop down to the button on the floor and it will lower the platform.The other player can now use the repulsion gel to bounce up to the platform and ride it up as the other player steps off the button.When the player rides the platform up, it will take them to another button that will release more repulsion gel on the far side. The one player will need to step back on the button while the other player makes their way to the platform and bounces onto it. Stepping off the button again, the player will ride the platform to the top and can then create another portal to allow both players to exit the chamber.
This was easily one of the more confusing chambers of the entire game. To start, create a portal under the repulsion gel dispenser and one on the angled plate at the top. Press the button and then have the other player jump up to the higher ledge and out through the field.While the other player is outside the filed, they will need to place a portal on the end of the funnel behind them and then one on the far platform on the floor. Now the player at the button will need to place a portal on the wall to the far left, over the energy field.
Now press the button and the repulsion gel will get caught in the funnel shooting up from the floor.The other player will need to move the funnel portal over so that the goo will fall onto the platform below.Cover the entire platform and then move the portal get some more repulsion gel in the funnel and move the portal that is at the end of the funnel to the platform down to the left, beside the closer platform below. Now the goo will fall through the portal and exit through the other coating the other platform.Now one player needs to jump across from blue platform to the other while the other player steps on the button to raise the catwalk at the far end. Once one player makes it to the far end, that player needs to fire a portal at the end of the funnel and to the wall below and to the right. The other player can now bounce across and get caught in the funnel and take the stairs up to meet at the exit.
In this test, there is a button on the right side and a light bridge on the left side.Have one player fire a portal at the end of the light bridge and then another on the far wall so it creates a bridge where they can run across to press the button.Once done, the other player needs to create a portal under the goo dispenser and another at the end of the light bridge that in front of the button on the right.Once done, press the button to drop repulsion gel on the light bridge and bounce up to the next section. Once you enter, one player will need to make a portal to the left, at the end of the light bridge and then another portal to the left on the wall.The other player will then need to run across that bridge, through the energy field to the other half of the room.
Once in there, the other player will need to create a light bridge by placing a portal at the end of the bridge and then another to the left.Once that bridge is up, the player near the button will need to press it to release repulsion gel onto the bridge allowing the other player to bounce up to the far end. Once that player is up, they will need to place a portal on the ground under the repulsion gel dispenser and another on the wall above the entrance to the chamber.The player will need to press the button again to release repulsion gel onto the bridge there, allowing both players to then reach the exit.
For this chamber, one player will need to place a portal under the repulsion gel dispenser and another on the two angled panels near the ceiling- one at a time of course.After each ceiling panel portal is created, hit the button and the sides of the walls will get coated.Once both sides are coated, portal up to the higher ledge and have the other player place a portal on the lower angled plate and on the floor. Now fall through and it will bounce the player to the top.Once at the top, repeat the portals for the other player so that they can get to the top of the bouncy wall as well.
As you enter the next section, one player will need to use a portal at the end of the light bridge- under the exit sign- and other to the left of the button so that the other player can go through the energy field on the far left side.Once through, the player there will need to make a portal under the repulsion gel dispenser and another on the angled panels above.The player controlling the light bridge will need to press the button to release the goo while the other player creates the portals to coat both sides.Once done, the player can then bounce to the top.
Once at the top, the other player will need to head towards the exit but first make a portal on the lower angled panel below while still having the other portal under the repulsion gel dispenser.Have the player still on the ground press the button to coat the wall and make sure it is full coated to the top. Once that is done, create a light bridge by placing a portal on the high up panel that is flat, facing straight down. The other player will then need to create another portal on the upper angled panel to the left of the light bridge. Press the button again and the light bridge will get covered in repulsion gel.Now the player controlling the light bridge can bounce to the top using it and the wall to reach the exit.
Head to the left side of this chamber and place a portal on the left wall and under the propulsion gel dispenser. Hit the button to drop the goo and it will coat the ramp and runway.Now one player will need to shoot across the ramp and press the button on the far side to drop a box out.When the box drops, the other player will need to run up the ramp and catch it and place it on the square button to open the door. Head down the stairs and through the next door to come to the next area.In here you will need to coat each alcove on the left wall with propulsion gel as well as the floors under the spikes.The floors under the spikes can be done using the angled platforms and the alcoves just by the walls.
Once they are all coated up good, one player will need to portal up to an alcove and create a portal on the wall in front and behind. Now the player will need to run through, and when up to speed, the other player will need to place a portal on the angled plate and on the wall that the other player is running into.Fire the portal when you hear the spike slam down and the player running will launch under the spikes.Repeat the same for the other player and when both players are through, a box will drop from the ceiling allowing both players to exit.
As you enter this chamber, place a portal on the angled lower platform to the left and one under the propulsion gel dispenser.Press the button to coat the ramp and runway and then portal over to it.The other player will now need to fire a portal across the area to the floor under the red arrow and another on the angled platform where the propulsion gel came out of before.As the player on the run way runs up the ramp, the other player will need to press the button to release the lens cube so it will fall through the portal and out the angled plate, allowing the other player to catch it in the air as they run off the ramp.
Once the cube is caught, the other player will need to create another portal on the flat plate on the ground and another again beside it once the player is in the air. Now the player with the cube can continually shoot up and down with the cube. When the player with the cube hits the laser, try and direct the beam to hit the turrets.Once they are destroyed, the player without the cube will need to create a portal on the higher up angled platform to the left.Once launched through there, the player who had the cube will need to create portals for the other player on both angled platforms.Once the other player runs off the ramp, the players will be regrouped at the exit.
To start with in this chamber, place one portal under the propulsion gel dispenser and then use the 6 panels to the left of the room -2 on the wall and 4 in the alcove- to shoot the gel out of.Once everything has been coated, one player will need to create 2 portals in the alcove on the left wall and run through at top speed. When the one player is doing that, the other player will need to place a portal on the high angled plate to the right of the alcove and then run to the far right and press the button to raise the catwalk.Immediately run back to the left and fire a portal in the alcove on the wall the other payer is running into and then quickly run back and press the other button to release the box.
The player on the catwalk will have to go all the way to the end of the catwalk and grab the box as it falls and quickly run back before the catwalk collapses. Once you have the box on the ground, take it to the button on the ground near the door and exit.
Immediately as you enter this chamber, run to the button on the left and drop the repulsion gel on the turret to take it out. Once it is down, walk to the end of the platform and bounce through the field on the right side and place two portals- one on the angled plate and one under the propulsion gel dispenser. The other player will need to place a portal on the left hand side angled plate as well as the two plates above the door so that propulsion gel can be shot out of both.Once the floor is covered, both players need to run and jump off the middle platform to reach the door on the far side. As you enter the field, go to the left and place a portal down below.Continue along the catwalk with the other player placing one portal on one side of the wreckage and another on the far side.
Go through and you will eventually come to an angled wall to the lower right.Place the other portal on there and go back to the beginning and drop off the catwalk to fall through the portal and launch out the last one that was put down. Head up the stairs and go through the door to enter the final area.Head to the right side and portal over the gap. Enter the energy field and place a portal under the propulsion gel dispenser and on all the walls where the black and yellow circles are. Fire propulsion gel through each of the portals and then place a portal on the floor in the center and one on the lower far wall.Run through the portal on the far wall and it will launch the player into the air, at the apex of your launch, fire a portal on the wall on the second floor and then use a portal below to go through.Once on the upper floor, place a portal on the wall opposite the grated floor and another under the dispenser to shoot propulsion gel through and to coat the box on the ramp.
Once the box is covered, it will slide down and will be able to be grabbed.Do so and portal over the gap and look for the opening in the wall with the orange arrow.Fire a portal through and another on a close wall and go through. To the left will be three lasers and each of these lasers when blocked will raise a catwalk in the next room. Place the box at the top of the ramp and let it slide down as both players quickly run across the catwalks as they rise.Once both players reach the other side, they will need to pull 2 switches at the same time. If done correctly, you will hear a bell and a door on the other side of where you dropped down will open.Portal over to the open door and head through. In the first room, one player will need to place a portal on the ceiling and one under the repulsion gel dispenser.
The other player will need to place a portal on the wall above the door and at the end of the funnel to the right.When done right, the funnel will be travelling down the center of the room. Now the player who put the portal under the dispenser needs to press the button to let the goo out and once it has passed the field while the other player stands on the floor button. Once the goo is past the field, shoot a portal on the wall that turns at the far end and another up on the right side wall.As the goo goes through, step back through the field when above the turrets to drop the goo on them. Now both players can bounce across using the walls to get to the other side.Once there one player will need to place a portal on the end of the funnel and step on the floor button to reveal a panel up on the wall to place another portal.
Now the other player needs to place a portal on the ground at the far end as well as one on the wall high up where the goo came out of and jump through.Now the player will be able to bounce high enough to land in the funnel and get taken to the other side.Once up there, the player simply needs to press the button and it will release propulsion gel outside in the main room.Head out there with both players and jump across to the large vault door.Make a gesture to the camera and that’s the game!
