Chamber 18 is the hardest test chamber ever yet in Portal.I hope you have your fingers(And your in-screen portal gun too!) ready!
Introduction
Chamber 18:How I explain it,Cold,a bit inhuman and a bit scary but its quite fun. Chamber 18 is the hardest chamber you may face but look on the bright side,you might get cake in the after you complete the next chamber.Or it will......
Part 1
Lethal water to take note here!To get pass the lethal gap,put a portal(I don't care what color it is anyway.)and put another near you.You may get pass it.Theres an area that has stairs,a radio and other stuff you may see in the game. Now to get pass the first 3 floors,put a portal on the ceiling where you may land on the floor and put another on the wall.Make the portal on the wall a bit lower of your level,since you can't walk just walk there,you have to jump there.Once you are on the floor that is near to the top floor,do your flinging thing.Sorry I may have to leave you in the game to find which portals to place.
Part 2
Go to the next hall and press the button to open a wall(A section at least).Some turrets are guarding this next room.Now just put a portal on the moved wall then to somewhere to get enough speed to FLING to the next room.This next room is usually a cube room + a weighted storage cube.Bring it and quickly get back by placing the portal on a platform which is really on the lethal water.Now quickly get there before you get too much damage.Release the cube on the button to take us to the next part.
Part 3
This is part is all about:
- Jump
- Portals(duh)
and
- A single fling
Now on your left,you see the floor on the bottom.Put a portal there and another on the platform you see on your straight.Now once you jump,you may see the floor of the higher platform,shoot a portal there on the platform floor and then wait for yourself to go through the portal.TAKE NOTE:Don't place the same colored portal you placed on the lower platform or things can get tricky.The last platform is slanted meaning you need to FLING to the exit.Put the portal there then you are flying.Proceed to the elevator as GlaDoS talks about blah blah blah.
You completed chamber 18!Continue on to the next chamber:Chamber 19!
