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.

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.

Sure, go on and hate my rating and me but I couldn't enjoy this mod because it was anything like Portal.

After fisnishing Portal + advanced chambers in no time I was looking for more difficult challenges but Prelude is just about knowing the maps and do some tricks as fast and as timed as possible.

Thinking with Portals? Well, kinda
Thinking with the map layout? Certainly yes
Being annoyed by all kind of death traps comming closer? yeah

It's just lame that the developer had to add challenge by making the game just less comfortable instead of making challenge based on logic.

I see this mod is pretty popular but maybe it's just because people like try (save) and error (load) instead of actually using their brain how to solve difficult puzzles. Be sure to hate my review because it's the truth!
