You can end this game without killing any body but when you kill more and more the end of it will be worse and worse!!!!
So Rusburow's discovery (ep 1) is represented by the color blue. The disease brought forth by the rats is in red (ep 2).
And death (ep3) is made of both the color red and blue. I guess this is not hard to find or notice, but it's nice there is some extra symbolism "hidden" in the videos.
I liked Part 2 most, but this one was the most artistically playful of the three episodes. Incredible stuff.
I am hoping that this game will fit the hype I have seen over the last 2 months. I pre-ordered, nad am looking forward to this game, so be good! (crossed fingers)
