This map takes place several minutes after Portal's events. Chell wakes up at the Aperture Parking Lot, among GLaDOS' remains. She's trapped by the fences, which prevent her from going outside. However, she can't climb them and her ASHPD is missing, so she's forced to return to Aperture Science to retrieve it. But it won't be as easy as she expects... To complete this map you'll need to use your best Portal skills, and be aware of everything around you. Don't be tricked by GLaDOS! Are you ready to return to Aperture? 2020 Update: Fixed cubemaps and some other problems, deleted GLaDOS dialogue entirely due to the absence of some "nags" and language mismatch. Plus, it didn't make sense. You know, because you murdered her. Oh, and credits are shorter now. How fast can you ABH jump?
