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.

It must be admitted that if you take nothing else from this mod, its sheer scale is quite exceptional. With new characters, voicework, puzzles and approximately double the length of the original portal (not to mention its difficulty in places) it is hard to den the dedication and hard work that has gone into this mod.
The storyline is fairly solid – although I expected the malice of on of the observers to continue – which is impressive and a testament to what can happen if a mod team sit down with a plot in mind. The plot in Prelude is simple enough, you are one of the first few test subjects at Aperture Science, and are set upon to complete the chambers in order to finally see the first run of the new GLaDOS system.
The test chambers themselves are not exceptional in terms of visual but what they do provide is an extension to the game play once you have completed the original game, the storyline ties in quite well as so as a prelude it seems to fit almost to the point where can feel Valve’s wicked sense of humour creeping through.
The puzzles themselves lead you through in much the same way as the original, giving you all the instruction you need in order to succeed in some of the trickier chambers to follow.
As you progress you will find that the difficulty ramps up rather quickly and far surpasses the original game, this is perfect for those who have just (disappointedly) finished the too-short 3 hours of portal and now want more and harder.

I have heard a lot about this game. Some call it "The Hardest Portal Mod Ever". This, it is most certainly not. I have played much harder mods. The hardest level was probably "Companion Cube Hell". I am not complaining about the difficulty. I actually think it is fine.

The biggest thing that detracts from this game are the voice overs. It was rather displeasing hearing about Abby's *** in the first few levels. That really made me stop taking the mod seriously. If anything needs work, it is the voice acting.

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.

Portal: Prelude and Blue Portals apparently have something in common: They both revolve around fling puzzles instead of puzzles that actually make you think hard. The difficulty in Portal: Prelude is mainly caused by this excessive amount of momentum-focused test chambers. However, Portal: Prelude is one of the few mods for this game to actually have an interesting story. The story is the greatest part of this mod, and is worth playing for that reason.

The mod is good but not my style. The tasks are difficult to perform but not to come up with. Still I recommend it to people I know like this kind of stuff
