Portal 100% Achievement/Trophy Guide

When I tried challenge map 16 least steps before watching the guide,
It's also when I noted my laptop's mute button makes me strafe right. Somehow.

Thanks for the guide, though i only used to get the long jump achievement

how many time the terminal velocity achievement take at exact same location as him

i missed a camera, i don't know where

On the last vanilla cake map, if you get to the second highest platfor, before the jump over, you can make a portal on the jump, and one on the second highest, and jump down to start, and then use the long fall down in the start of the lvl :)

Tyvm for making the video ;) did help a lot, I sub and like for your kindness

I dont have any radios

Underrated AF!

Thank You Sooo much!!!!

Thanks dude. Not the most fun platinum, but it still counts.

no way to throw the f*in cube on the other switch WITHOUT falling down from the first in ch13

Thankyou this was a big help!

Thx bro, i need it 👍🏻👍🏻

I love you so much

Help 😖the developer mod don’t want to active help !

im missing one camera what a cancer achievement

Finally got 100% after 16 years of owning the game. I had some of the achievements from early on. The only remaining were the challenges in the advanced maps. Those were probably the most difficult. Least steps and minimum time were the hardest.

Challenge map 16 is brutal..... it says you get "52" seconds but 20 of them is GLADOS TALKING >:(

Challenge map 18 is also giving me trouble on the time portion - I just can't react quick enough to get through it.

Those are the last two things I need to gold... and I'll probably never do it sigh

great guide

For me the radio at the start area has no light when i bring it to the button it doesnt play the morse code and then there is no radio at the chamber 01 how can i fix that

I beat the game but for some reason, I didn't
get the partygoer and the heartbreak achievement

Loved the walk through up until the final minutes why not show exactly how to get through the maps

trash guide

i didnt get lab rat even though i got blue and orange portal guns? also didnt get fratricide even tho i incinerated the cube

chaimmer 4 will not drop the radio it's stuck up there

challenge map 15 is a HUGE BULLSHIT

CAN"T THROW CUBES! I SUCK AT THIS GAME!!!

I can't believe he suggested cheating as a viable method to completing all challenges. I have lost almost all respect for you.

I would say it's mostly good, there were some parts that were glossed over. i.e. The challenge maps. So parts he would say just portal over here, but it's through turrets and areas that can't be 'portaled'. Other than that great guide.

Obrigado, ajudou muito

this was hard as shit, I don't know how they expect people to do every challenge in time if there's hidden shit on the last ones.

This... was certainly an experience... I. Hate. Timed. Maps. I REALLY HATE THEM AKDHSAUBDHHU i have anxiety, they were such a pain in the ass!!! there were times where i'd just kill myself out of frustration bc- askdhsadksa uk
Honestly, i wouldn't have done it without you!! Tysm for this video, it was the only reason why i was able to fully complete the game and i'm really glad i did

I missed one radio how do i find out which one it was ???

i gave up on least steps, the 2 initial steps section is impossible

Thank you.
