@greg3.14: In Half Life 2 Part 2, we learned about Aperture’s prized ice breaker ship the Borealis, that went missing after it teleported away from Aperture. This scene showed blueprints of the Borealis that players could find in the data files. One of the documents is clearly signed by GLaDOS. The Borealis was built in the 1970’s, years before GLaDOS was, so this was actually meant to be Caroline’s signature but at the time that Half Life 2 Part 2 came out, GLaDOS backstory hadn’t been fleshed out. This was just to establish Aperture and Portal in the same universe as Half Life, later they retconned GLaDOS backstory with Portal 2. #cavejohnson #portal2 #gaming #funny #memes
