It is a non-linear map which have many paths to take and reach the end. The point is, that you play a map one time and you are happy. Then you have a little break in Portal, because there aren't any new released maps for some time. But the answer is here: play the Deja-Vu again, but choose a different path with different puzzles. You can choose freely the way that is going to lead you to the end. Thats it!
This is the Trailer of the mod Déjà vu.
This is also just a test trailer, the real trailer comming soon.
I hope you guys like what you see, and I hope you want to play it when we release it!
