Portal: Prelude, as its name states it, is an unofficial prequel to the game Portal. Its story revolves around the pre-GlaDOS epoch, even before she was plugged in. At this time, test subjects were monitored by real Aperture Science employees, whose work was tedious, lengthy and repetitive. This is why they decided to build a great artificial intelligence that could both replace them in these difficult tasks, and also take responsibility for many other tasks within the complex and compete with Black Mesa's superiority. All employees of the Aperture Science complex are now eagerly awaiting GlaDOS. Maybe even a little too eagerly, as the upcoming events will tell... This game is totally free. It offers a bit more gameplay hours than the original Portal, with 8 chapters, 19 test chambers, 48 challenges, 6 advanced maps, a brand new storyline and more than 400 lines of english speech with dozens of subtitles translations.

Portal:Prelude is a GREAT mod...The thing that brings it down onw star is what they used as voices. It doesent sound so great when you're using computer voices instead of real people. But the levers are fun and challenging!

Really great Mod
Very chalenging but doesn't make you feel lonely like MANY other mods, so you always want to continue. Most of the tests are well put together.
The storyline is pretty accurate, almost as if it was made by valve.
The Visuals are great, never looks bland or boring.
I love the voice acting. the dudes that guide you always fight over the stupidest things.
This mod is underated. I recommend you give it a try.

A little hard. Maybe a little too hard. But the plot deserves 9/10.

Impressive for such a small team. However the human voices sound too much like text to speech and the puzzles are non-intuitive: too hard for me. I had to give up frustrated. Also the game crashed several times eating lots of resources although the graphics were simple (I was in a corridor made out of squares) with 2 portals. I then skipped right to the ending where I was killed all the time in the finale. Sorry, I had much more fun with the original Portal.
