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.

Here we are, Day One. The trailer is up and running.

Posted by NykO18 on Sep 15th, 2008

The trailer is up and running, the news is posted on forty of the most important Half-Life related websites of the world, and I'm anxious as I've never ever been. I really hope you will enjoy what we did. We worked hard during eight months to bring this game to you. If you have any question, please ask in the forums.

Looks promising so far :) If you want, I could translate the game from english to finnish. As for previous work, I did finnish subtitles for the "Get a Life" mod.

If you are interested, feel free to pm, or mail me :P

This mod won't die, in fact, it's already finished, there is only a few things to fix before the release.

Woah, now that's the way to announce a mod! :D
I think you've chosen the right time to announce your mod.
Not too early, where pre-pre-alpha screenshots and videos (or nothing at all) may deter people away from the mod, neither too late, so you're able to generate some PR/hype.

As for the mod: looking great, probably gonna be that too.
Edit: Was about to ask if this was another mappack, then I checked your site. ;)
Will you try to implement the same kind of humor as in the original Portal?
If you do, thread lightly, it's a dangerous path!

Very nice, I hope valve recognizes you for your work as well as the rest of the gaming community. However I doubt valve will since there working on their own Portal Prelude.. Of course were talking about Valve and not EA. Good thing this isn't an EA mod or you might have gotten a very angry letter!
