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.

Description

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). Please note because of steampipe there is a simple fix that you need to make to gameinfo.txt which is the same for every portal mod.

Noooo. The cake was a lie, because GLaDOS said that everyone will get cake, but what they got, was death.

First, you must go to where you downloaded it to and then use that to install the game. Then, Steam must be restarted(or just started, if it wasn't running when you installed Portal Prelude), and then it will be in the games list of Steam.

put the download under steam/steamapps/sourcemods then it will be in your steam game list as a third party mod :D

Will it replace my Portal Files if I use the installer? Or am I safe if I don't back up the Portal Files?

No, just install into the folder sourcemods, Restart Steam, and there you go the mod should be in your games library on steam.
