You are an abandoned test subject... You should've woken up to a destroyed and decayed Aperture Science... But you awaken to the sound of Cave Johnson... The facility you knew no longer exists, instead you awaken two months after a Hostile Takeover... Welcome to Aperture Vault Science Network Industries. The testing has just begun.
These promotional images were created after the logo was established in paint and touching up the image in GIMP...
Enjoy
The basic concept that Aperture Science would be acquired is unheard of, but considering this occurs in a parallel timeline; this story has a group called Vault Trust INC already take over Aperture during the in-between period of Portal and Portal 2, Let me stress this enough, this is in a parallel timeline (where Cave squanders the company's money on moon rocks, lots of moon rocks...)
