Portal Bonus Maps: Chambers 16 - 18 Gold Medal Time Challenges 

THANKS TO THIS TUTORIAL CHAMBER 18 TOOK ME JUST 15MINUTES OF SUFFERING WHEN I FINALLY MADE IT JUST ON TIME! THANK YOU! This tutoeial was so easy to follow, incredibly greatly explained. This was amazing, thank you.

I know you probably aren't reading these anymore, but I still want to say that the way you demonstrated everything in this video was very unprofessional but I think that made it easier to understand in a weird way. It's almost how I would describe it to myself. Good and helpful video :)

These have been so helpful. Thank you for making them!!

This video is really good and helpful Thanks!

thanks, laST ONE WAS A LITTLE TRICKY BUT I GOT IT

you explain very well I love it thank you!!!

This is the best tutorial about bonus maps in RU-vid and if you can do the steps and portals, it will be amazing i belive in you👍👍

It's too bad I didn't find this video like 3 days ago when I was completing all the challenges, but you basically explain what I found in other videos. That trick is called portal bumping, and I honestly don't feel bad for using it. I know it's technically cheating, but it turned the time trials and least steps from frustrating agony to actually sorta fun! EDIT: I actually used the camera to block the door in chamber 18 instead of grabbing the box, and I guess you could also make it work with one of the computers from Rattman's den. Idk if it really made it any easier, I had to reload sooo many times from the camera spazzing out and rocketing away from the door, closing it again.

I got 0:26 on 16, thanks man.

I love Portal 1 but those bonus chamber are just horrible, especially the turret one because of how poor the camera is when flipping from upside down.

Does the glitch with the portals still work in 2020?
