[SPOILER] Penumbra Overture Demo Secret Easter Egg

[plutomaniac]

I played the demo today and when it finished I said, how small it is? I should make it a little bit bigger. And so I edited the map script file to remove the dog so that I could explore the last area a little bit more. I succeeded and while playing I run into a secret easter egg that can be found, at least easily, without the presence of the bad dogie. Have fun and comment:
