We all know the story of when Chell awoke and defeated GlaDOS, but what about the story behind Aperture Science? This fan made sequel to Portal 2 tells the story of a new test subject in the 1950's and how they changed Aperture forever.
This screenshot shows parts of the old Aperture areas at the start of the mod from the 1950s. The map is still in development but thoughts and opinions are welcome. I don't know how much I'll be able to work on the mod but I'm going to try and get enough done to make a teaser video. Thanks for checking out the mod :)
