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!

Now seriously, you'll have to be very observant if you want to escape the labs...

Are you ready to return to Aperture?

This was enjoyable, however your metal textures are quite boring. Also, it the way you needed to go wasn't very clear after the cake room. Also, those coloured buttons/cubes are painful to look at.

The start of Test Chamber 19. Still not the end of anything.

Cake. STILL not the end of anything.

Man, you need to be clearer with when the map truly "ends".
