Portal: Prelude, the fan created prequel to the blockbuster Portal, is now being offered up from Planet Half-Life and FilePlanet.
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, but 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...The official release isn't for another day, but a 24 hour FilePlanet exclusive never hurt anybody. We'll have a mirror up once the exclusive period is up.
