The sixteenth video in a walkthrough requested by XanderMisfit. So that Ending, is it supposed to be bad? I mean, did I make the evil choice? It's somewhat ambiguous the way the Bird-Man leader talks, but I think he just means rule the world in a metaphorical way, not as tyrants. The drawing you see at the end is based on the Nazca Lines drawing of a deformed or stylized hummingbird. You can see the real deal here: http://gosouthamerica.about.com/od/nazcalines/ig/Nazca-Lines/Hummingbird--Nazca-Lines-2.htm

Just to clear something up, I'm not a conspiracy theorist who believes aliens did it. I think there's a rational natural explanation for everything, including things we don't know or can't explain yet. For the unexplained, I'll just answer "I don't know", instead of sticking non-answers like "aliens did it". Do I believe they might exist? Yeah sure, keyword being MIGHT here. If I get good evidence that they do or if I unambiguously see them, I'll believe it.
