Year 2552... The Earth is no longer habitable since year 2401 due to the atmosphere collapse and temperature rise. Human race has been forced to live in the different colonized planets into the Solar System. This was called "The Second Exodus". After the "Enceladus Atmosphere Implementation Program" (EAIP) succeeded in year 2295, Saturn's moon Enceladus turned into the most important human colony into the Solar System altogether with Titan's. After the EAIP implementation, Aperture Laboratories developed their more ambitious testing program, The Enceladus Initiative.
And this is another view of that precipice. I really hope that you like this puzzle where you are forced to do everyting in height...
Thanks Tile! Yes, most of the textures are stock ones from the game indeed... I only like to make a custom one when is completely necessary. As for example that one we made for the laser fields sides (they're down there in those panels sides in fact... a bit hard to notice with the fog though). As mentioned in other pictures' comments, there will be also new texturing of the models (re-skinning) which I will make an article about maybe on this week.
There are great textures already in Portal2! the key is how to combine them properly to reach a personal style that can be interesting to ppl.
