Based on Portal: The Flash Version, our very own Hen Mazolski brings us all the levels and concepts back to the original Portal version, in this huge mappack!

This time, experience Aperture Science from a different perspective, before the time of the original Portal, as a different test subject.

This mappack includes ALL 40 levels from WCS's Flash version, additional bonus levels and features. All together, we've got here over three and a half hours of amazing gameplay.
