Since there's no way to officially review Workshop content, I figured I'd just leave a comment here saying this was an enjoyable collection. Very creative and puzzles that aren't too easy or too hard in my opinion. Well done.

I really love the atmosphere of this map series. You wake up in an overgrown, rotten part of the facility. GLaDOS isn't there, and the cores are gone. You are completely alone. It's just you and your portal gun. You must escape on your own. However, sometimes, you can't help but feel like you're being watched.

Puzzle 4 had me confused for all of 10 minutes before i realised. it was immediately apparent about the second minute into that puzzle a piece was missing. anyway, i got past that without much issue, puzzle 5's bottom ramp is a little too strong or the ceiling isn't high enough up, i'm often hitting the ceiling rather than travelling through the portal unless i'm exactly precise on where i stand on the flipper.

puzzle 5 was a little more tougher than puzzle 4 though. the platform to the exit was a little sadistic. that was great! xD

puzzle 99 was fairly straight forward, although i would of liked to of been in those other chambers solving puzzles there at the end of that puzzle. :P

Even if you didn't make many more maps (TL;DR he didn't, at least in his workshop ) your name will be eternally remembered, BanJaxe!

I like the style you used and the aesthetics very much, but both in combination are just perfect!
I hope you`ll do part 4 soon.

more maps please

Thanks a lot! Thumbs up!

awesome series!! the fisrt map almost got me xD!! really great job!!

much appreciated genuine level design! You should work with valve on portal 3, dude. Great job!
Thanks for all the work you put in the details. :D

Blaise The Hawes Great

This was such an awesome series, I really enjoyed it! Great work! Loved the unique use of some things I had not seen before, like the sideways portal and the angled faith plate!

this is wow it could actually be like,portal 3!

You've really captured the spirit of Portal 2. I love you :'(

This was really unique. The level designs are very creative. You really made it feel like it's falling apart.

These environments are beautiful to look at.

Nice.

Fantastic set. The chairs on the ledge behind the last elevator were a great touch. "This thing like seeing, but NOT with my eyes!"

Great concept, well executed. Really captured the feel that the place was falling apart. Loved it!

eh, valve just needs to learn to count to 3, so as to release portal 3 :D (would say half life 3, but personally, i prefer the portal series) (inb4 incoming hate)

So...the destroyed Aperture at the beginning of Campaign, now with a storyline? This one should be fun...

you ripd that title off

It's insane how good these are. It makes me want to rip my hair out but at the same time admire you. The best chambers I've played.

Really, really excellent collection.

This is amazing

NICE JOB

Thank you

you're a genius !

Thank heaven- a Portal game with a real ending :) Great maps but they took me hours to work out... Not saying that's bad or anything...

Phenomenal maps. The best I've played so far, by far.

Part 2 was rather hard, especially at the end where I needed to watch the walkthrough. :-/
Part 3 again was amazing. Thank you! :-)

Прошел с удовольствием.Хороший дизайн карт,приятно играть.Таки трудные головоломки и это плюс этого мода.В общем отличные карты.Стоит поиграть каждому.
Nice map! Great work! Thanks!

This is truly art.

Someone please give this guy a medal

Fantastic! Felt like I was playing the game all over again. :-)

Utter brilliance.

I enjoy this collection...

Absoluately amazing. Don't say I've played Portal 2 without playing this pack!

Truly the best map set I've played on Portal. Awesome work ! The maps make you think outside the box. Part 2 and 3 drove me crazy :).

@BanJaxe thank you so much! Now hopefully I can create something amazing like you have!

@The Silent Riot
It was made in Hammer. You can get Hammer by running the Portal 2 Authoring Tools in the Steam tools section. The Valve developer wiki is a good resource:
https://developer.valvesoftware.com/
https://developer.valvesoftware.com/wiki/Level_Design_Introduction_(Portal_2)

I would like to know how to make maps like this... I've made one using the tools supplied within the basic workshop... but they don't give this level of depth... I would really like to learn how to make art like these...

Now these are maps that should have been in the story mode.

The look of the maps matches the theme extremely well. Some of the puzzles were fairly difficult. Very nicely done.

Way to raise the bar! These levels were fantastic!

Just click subscribe and then load up Portal 2.

Wonderful, beautiful, awesome. A rare combination of interesting puzzles and an environment designed with love for detail.

Brilliant maps! These must have taken several weeks to make. They're a wonderful take on the decaying theme in the beginning of Portal 2. Please make more!

I quite enjoyed it. Part 1 and 2 are excellent laser puzzles with tricks that I haven't seen before (not that I've played a lot of maps though). Part 3 makes use of gels and is interesting, if not challenging. Any chance of a part 4? Perhaps you don't escape at the end of part 3....

Terrific! I especially like the conceptual unity in parts 1 and 2. Part 3 was a bit different but still very clever. And nice puzzles!!!!

Very nice!
