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.

This new version is shipped with more than 115 bug fixes, improvements and additions (since 1.0.0). We know everything's still not perfect, but we believe we put enough work in this mod and thus, this version should be considered final (except if something really bad happens).

Until 2008-02-02 11:00pm (GMT+11), the 1.1.5 installer was corrupted due to some upload problems. This is now fixed. Sorry for any inconvenience it may have caused you.
The file should go back online as soon as moddb's mirrors are up to date.


That's it, the new Portal: Prelude 1.1.5 complete installer is released!
Head up to the download page, and enjoy! (the complete changelog is included below)
Please uninstall all previous versions of the mod if you already installed it.

Also, there was so much changes to the game files that it's pretty much useless to release a cumulative patch. It would be nearly as big as the complete installer itself. Please note that there's nothing worth redownloading the whole mod again if you already downloaded it, as it's mostly graphical improvements, optimizations and minor bug fixes.

A really awesome mod that was well thought through, even though some of the chambers are just impossible. I was stuck at the first part with the four turrets for a long time...

Anywho, the only real issue with this is the voice acting, or lack thereof. When you use a computer, there's no emotion. This kinda' ruined the game for me in a couple of spots. Anyway, keep on going. This is looking great.
