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:
Youtube.com

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.

It's 2020, and no updates yet. Mevious, can you fix some bugs and...?

EDIT: There is the list of improvements I expect:

1. Improved GLaDOS voice. She must be voiced by actual human rather than text-to-speech. Voice actor must be talented enough to do this.
2. A brand-new ending, which I can't tell because of spoilers, and I don't want to ruin an surprise.
3. Upgraded test chamber design that will make it look more beautiful and pleasant to eyes.
4. More cool, atmospheric music, which surely fit the tone of the Portal 1 sourcemod.

Iunno about number 1.
15.ai is pretty good, specially for GLaDOS.
Altho I guess her voice is the Portal 2 voice instead of the Portal 1 voice, but I wouldn't personally mind.

Haven't played this yet, so iunno how bad the text-to-speech is, and considering it's from 2010, I'm pretty sure not that good; but I don't think it "must" be voiced by an actual human.

This was an absolutely awesome Portal modification. For anyone who loved Portal but found it a bit unchallenging, this is he cure. There were many moments that I just could not figure out how to get past certain levels. It really made me think about what I needed to do, well beyond the original Portal game. The only problem I had was a weighted storage cube would not drop from the dispenser and replace one I destroyed intentionally near the end of the game. I had to force a drop using console commands. The voice of GlaDoS is not the original voice from Portal, but the designer obviously didn't want to be handcuffed by the original sound files and did a good job mimicking the original voice. the script could have been a little funnier, but it seems the designer took a more serious tone with the mod. All issues aside, the designer is a mad genius who should be congratulated and rewarded for this insanely well done mod.

Nice mod but I found a mistake in the level design in the chamber where you get the dual portal gun. If you press the button 10 times or more the gun does not hit the portal surfaces anymore. I think its a bug because the gun does not rotate in 90 degree angles but more like 89 degree.

A very good and creative mod. The only thing that made me rate it 9, is the ending: very boring, you could make it better, Mevious.
And other thing: the new GLaDOS voice sucks... but the chambers... are awesomly well made, hard and beautiful.

All I can say is: download it.
