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!

In the first few minutes I had with Portal: Prelude, I was very interested and somewhat curious. The voice acting wasn't that good. It didn't sound like a human, it sounded robotic and it gave me the impression the people who were talking were robots. The sign textures were low quality but the rest were fine. The gameplay was good. The test chambers were a refreshing new set of tests I really enjoyed. It was interesting yet cool that you started with the an orange portal gun and not the blue one. The tests were fun and the story was really cool and interesting. All I can say is that this is a must play mod for anybody who owns Portal.
