Recreating the original Portal in Portal 2. Demo Map placed after the Portal Maps.
There are several projects aimimg to recreate the original Portal in Portal 2. This is my version of all that stuff.
What you can see in this Map is the first Map after Portal 1. I won't recreate all Maps because I want to add my own stuff in this.
To play this Map, place it in this directory: /Portal2Dir/portal2/maps
Then fire up the game and execute this command: map e3_trailer_concept
A better place to publish these maps would be

there is a huge community there who would give feedback, you would also get a lot more downloads
