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.

I'm liking Pro so far, it is tough. I just got frustrated a lot because I may be completely DONE and I can finish the puzzle, but then I see a little button I haven't seen before. *press* *everything is messed up* And I got headaches from jumps, but that's normal.

The only thing I would change is the voice actor. I don't like her. Ironically, I don't like her because her voice is too emotionless and robot-like. It's blocky, I should say.

ANYWAYS, this is masterful. GREAT WORK!!!

I like the emotionless voice. It's eerie how she's so calm when she's explaining her evil intentions to the player.

Another question: How did you get the moving acid to render properly ?

In both instances the moving acid is a func_water_analog parented to a moving entity. The fog is mocked by an env_fog_controller which is enabled when you fall into the water and disabled when you leave.
