Portal Challenges: Least Time

I just want to say that after finally doing chamber 18 (by myself) i spent at least 20 minutes absolutely annihilating that one turret to the left which killed me at least 80 times until i did it.
Your way to beat this chamber is really impressive btw!

dude im just gonna say this video saved me from destroying my mouse

lmao at the turret chamber he doesnt even double portal bumb

“This could take a vary… vary… long time.”

13 seconds later

challenge 14 is not possible i tried it like 20 min but no its so hard to time it

Wanted to break my monitor on 14 holy

For anyone who's having problems with the camera in chamber 18, you can do it with the cube. Do the chamber just as he's doing it, but instead of taking the camera, shoot on the platform that lifts after you press the button, fall on the right to get the cube, then you have to fall to reach the lower level where's the another button and just use the cube as usual. It sounds like it's slower, but it's better to do this instead of trying to use the camera with those buggy physics

really useful

After 100%ing all of portal I can safely say that the challenges are android hell

18 is awful lol. But to save time, shoot a portal by the door that the big button opens, then go into the room with the camera, shoot the camera down, then put the 2nd portal right where the camera will fall. Go through that second portal, and it'll save you a good 10 seconds.

After trying chamber 18 for an hour, I just resorted to using wemod's no-clip to get pass it. The camera part is rediculous.

DUDE, I CANT EITH CHAMBER 14

Whaaat, i felt like a pro when completed chanber 13 in 36 seconds after hour of attempts

Whaat Test Chamber 13, 17 seconds, on a smartphone, i would had 15, but i stuck in the wall at the end

Well then, looks like I won't be going for these challenges 🤣

everyone here talking about the camera on level 18 I got it like in my 4th attempt guess I'm lucky I'll take that xD

HOW DID YOU GET THE POX ON 13

i did it and i got all achievements in portal and never have to do any of this again

Places a portal on the OTHER SIDE of the wall.
HAX!

Thanks a lot dude, i saw lots of walkthroughs for the chamber 18: the one taking the tiny box at the beggining, the one that glitch you at the end part, the one called saveglitch... Yours, with the camera, was the best honestly. I'm gonna try the less steps on 16, 17 and 18... I think i'm gonna cry hard xD

I guess it's easy to realize but I still haven't read any comment about how you should save after each milestone so that you can load and continue from there if you make a mistake.

my goal of chamber 13 was 14 and got 16 ‼‼

I don't get the achievements, because when I pass the level, the game shows that I cheated

Thanks a lot, the trick at the begin of 16 was a life savior.

The solution to 17 is some horseshit

Whoever designed these challenges is a sadistic POS.

idk why everyone is saying that least steps is the worst it is CLEARLY least time ffs

Chamber 14 is PAIN. WHO THOUGHT THAT IT WAS A GOOD IDEA TO PUT SEVEN SECONDS FOR GOLD?!

Even with these guides, it's still too impossible to do these challenges

A un sirve,muchas gracias

Это самая напряжная часть из 3х видов испытаний! Особенно 14 полигон! 😣

god this took me an hour but the least step one i still hate it

Chamber 15 is genuinely awful

YOU ARE THE LEGEND!!!

im feeling bad

in the 18 chamber, just go to the door and do ent remove

For anyone struggling with Chamber 14, you can make it a lot easier by jumping down the hallway, placing a blue portal next to the exit platform, placing an orange one on the ceiling to the left, jumping through and then placing another orange portal to propel you onto the exit platform.

Ok how tf are you even meant to do the first one on Xbox 360?

Finished all the challenges. Never again.

finally, i did it. thank you man

For those that can't manage to do chambers 14 and 18 with these methods I higly recommand you check out Xorven's run, they are really easy to do and will get you the gold

bro am I the only one who's struggling with chamber 14?? My game is fucking r3tard3d the portal thing isn't working

I just got 100% Portal achievements and I must say it was the biggest accomplishment of my summer holidays

in CHAMBER 13, YOU CAN JUMP TO THE BUTON INSTEAD OF THROWING THE BOX
