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 The only downside is voice acting, but that is only because the creators were french, and the game wasn't originally made in english, so their voice options were quite limited.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 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.

Kind of disappointing. The story is not all that great and the puzzles are difficult but in the wrong way. By that I mean that it's easy to figure out what to do but actually doing it can be pretty hard.
