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 mod do not deserve 8.6. It should be 9 at least. Also I can't understand persons who gives lower than 7. You can't give a low score for a game for its hard. If you don't know how to play, dont play any portal mod. Thats all.

Also makers of this mod first language aren't english, so you cant blame them for they are terrible at voice acting. This mod includes orginal ideas, orginal gameplay, orginal chambers, orginal story. Also difficult is not very hard for a person that he knows how to play portal. OK maybe hard, but not very hard. You should be patient. I like this mod's musics. They are relaxing me.

About this mod, you should have to play.

Probably the best portal mod I've ever played, it has all new characters, new enviornments, new tools, and an amazing story that is worthy of being part of the official half life/portal universe. The only downside is voice acting, but that is only because the creators were french, and the game wasn't originally made in english, so their voice options were quite limited. Well, at lease its a british microsoft sam...

I really can't believe that we actually had a prequel before Portal 2. I didn't even though that Portal 2 was as great as it was (I mistakenly thought it was COOP only which turned out false). This mod did a pretty good job at tiding people over. It was harder than Portal 1 and 2 combined. Particularly tests 15, 17 and 18 that I took me awhile to even solve (15 and 18 had a obscure way to get the energy balls dispensed and 17 was just to boring). Some where a little to finicky, like doing a trick shot while doing a infinite loop on more than one occasion. But it does some important things very well, first off it gets progressively more difficult without feeling like its convoluted (17 was the exception, great in theory ie inventive but boring). Great idea to use the synthetic voices to, eventhough it looks weird on real people towards the end. Its story is pretty good, not great but better than anything I could have come up with. And a nice homage.
I think that it did well with what we had to work with, and remains to me perhaps the best Portal Mod and a nice companion to Portal 2.

I was thinking about giving this 8.5, but I realized that this mod
deserves, 9. It was well made, enjoyable and great unofficial prequel.
Altought I didn't kind of... Enjoy the voice acting.

It was cool to see beginning of GLaDOS's life, and how she
took over the facility.
