You awake in a pile of broken glass, with a pounding headache and no memory of how you got there. Your only goal is to find your portal gun and escape from the building.

Note that this is my first map ever created using Hammer World Editor and it was originally created using the Alien Swarm SDK, before the Portal 2 SDK was release, so I apologize for any sloppiness in the map.

By the way, I have seen many chambers with cubes set at an angle or on thier backs. This is not a violation of portal physics. It is the evolution of a very rich platform!

Excellent map! A great logical adventure in a wonderful environment. Thanks!

Great chamber. I loved the laser puzzle. Kept getting burned, but I got there in the end :)

If you like to think outside the box and you want a real challenge, try my chamber "Misdirection" at http://steamcommunity.com/sharedfiles/filedetails/?id=140602475

Nice work, it could make the history of portal 3

On the whole, I liked it. I agree with wildgoosespeeder about it being tedious with all the crawling, and it was a little too long overall. I disagree with wildgoosespeeder and lightmare about taking advantage of the game physics. I think that is perfectly reasonable to expect the cubes to act in-game the way they would in reality. Not the same thing at all as exploiting a glitch, this is expected behavior. If players need to learn something new, so much the better!

What even happened at the end?
