Portal Pro is a set of test chambers focusing on solving puzzles locally rather than using complex fling techniques. The goal here is that the solutions are hard to come up with but easy to actually do.

Hey everybody. I just wanted to thank everybody who has taken an interest in this mod, especially those who have posted their thanks, comments, questions and suggestions! We're nearly up to 300 downloads so far, with downloaders from all over the world!

I would like those who posted concerns to rest easy, knowing that I've been reading them, and will be fixing many of your issues, as well as some ones I've found internally* in an upcoming version of Portal Pro.

Also, for those of you who are still stuck on a level, a tester and I have recorded and uploaded a walkthrough of every single level onto youtube, and they can all be found here:

And for all of you who have beaten Portal Pro, keep in mind that there are a few challenge maps that will test you even further, but only if you unlock them by finding a special items hidden throughout the game!

* Currently Secret Chamber 2 is unbeatable because you start with a blue-only portal gun. This will be fixed in the next version. In the meantime, this is how you can fix it:

  1. Start Portal Pro with the argument "-console"
  2. Once inside the level, press the ~ key to enter console mode
  3. Type "upgrade_portalgun" and press enter.

For some reason, right before the main menu loads, the game quits and says that "a Source engine game is required to run mods". What's causing this? I own Portal.

It means you got Portal when it was free and can't play mods. You need to buy another Source engine game with the same Steam account.

Мод офигительный! Очень рад что обнаружил его. Спасибо. :)

Как пройти карту где GLaDOS принуждает утопиться в жидкости? В комнату пролез, на кнопку нажал -- жидкость рассосалась, а что делать дальше? Помогите.

Best mod ever. I got to ask you how is it possible to create such difficult test chambers, I mean, how much time did it take you to think about it ?

Me have a found a quick shortcut to the #.17 Passage. Take a look :

Ok this is a REALLY good mod. I even had to noclip though 2 levels due to how hard I foud it. First one was the sewer one where GLaDOS has to drain because door broke, second one was the first fire pit. (I Actually knew what to do, I couldent do it though because I was lagging and I spent Half a hour trying to fling myself, the lag wasent letting me move my mouse fast enough though :/ You should change the fire pits to water because The smoke and flames cause extreme lag.
