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

All the files needed to make Portal: Prelude run. This version is exactly the same than the "installer" version except that it works better for Mac OS since it's a simple zip file. Valve ported their Source Engine under Mac OS without telling anyone and especially not me. Now I don't have the time, motivation and knowledge to port the game to Mac myself, but I can provide you with a zipped version and instructions on how to make it work. It's a bit tricky but so far it worked when we tested it on a Macbook. Instructions on how to make it work are available when you click here:

Is it better than the previous version in anyway?

Also, will it repalce my Portal Files? Or am I not required to back up my Portal Files?

ln -s "../../sourcemods/portal prelude" portalprelude

but when opening it through steam through portal, it's not working (black screen for indefinite amt of time) because it is missing something like background.vbg. Too busy to deal, any ideas?
