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.

just a small bug in the sewer level.
after dropping the box between the two doors that opens with the switch, what i did was put the box right next to the second door (the one closer to the exit) and portaled myself to the second door switch.
then i pressed the switch where the wall moves forward (used when your block gets stuck in the middle of the passage) and quickly stepped on the switch where the door opens.

what happens when you do this is that it pushes the box through the second door, but not falling into the pit thus making it impossible to continue the level.
maybe you could fix this by the pushing wall also coming out from the other side of the second door, so that the puzzle can continue even if you get your box stuck there
here's the screenshot

Nice catch. Another solution would be to add physics collision where the door is to prevent the cube from going through it in the first place. Added to my todo list along with a few other places the player can get stuck.

I just got done with this mod, and I'm giving it a 10. This did what the original Portal did but better. The puzzles where you can only shoot blue portals are very well designed as you can use multiple solutions not to mention there were lots of them too! In some of the puzzles later on where you can shoot both portals I was even sitting there thinking where the hell I was going to start. To be honest, I usually go into these portal mods/custom maps thinking I can out-smart the designer by finding massive skips and mapping issues however with this particular mod it was quite hard to come up with much. That being said, I did find some large skips that bypass whole chambers and a bunch of small skips that let you pass chambers a little quicker than intended. However I can't criticize this mod for those things as this is portal and there are too many possibilities for someone to block them all. I also burst out laughing at the joke about the corpse near the end (I think you know what I'm talking about :)).

By the way, the GlaDOS fight was epic.

Overall, it took me a little over 2 hours to complete which is quite a long time for me to pass something Portal-based. Seeing as though I can only write 2k characters, I will leave it here. Thanks for the mod!

Great mod! I played through it all in one day. It was really fun, and not really to hard.
There was a glitch at one spot where I couldn't climb on a cube. I just fell through it, so I had to cheat at that part.
Also the ending was epic! And I beat it on the 1st try, without dieing at all.

Now I've played almost all Portal mods out there on moddbm, and all I can say is that this is hugely underrated. My favorite is Portal Prelude due to its story, but this modd is without a doubt on 2nd place.

The puzzles in this modd beats the puzzles in all other modds, even Portal Prelude I think... And the new computer voice is also awsome.

There is just one thing that could be better in my opinion, and that is the ending. It just seems so abrupt and leaves the player with the questions 'Did she come out and did Glados die?'.

Anyway, really well made modd man. Recommended for people with much patience.

Is there a way to play this if Steam is not installed?

Thanks :)

Not that I know of. You need Portal to play this, and if you have Portal then you should also have Steam.
