Okay, before I post this, it's from I Am Alive's wikipedia page.. Yeah,not a hugely reliable source, but people go on to much about it not being reliable, it usually is.
"I Am Alive is an upcoming action and survival video game by Ubisoft to be released on PlayStation 3, Xbox 360, and ported to Microsoft Windows. The game takes place in post-apocalyptic Chicago after a major-scale earthquake, and tells the story of a man named Adam Collins. The game was announced at the end of Ubisoft's E3 2008 conference. The plot focuses on Adam's life during the aftermath of a 10.3 magnitude earthquake, which shatters his life as a citizen, while the rest of the world is under a water crisis. The rescue team fails to arrive, Adam gets caught in chaos that gets worse by the hour. Adam sets up a refugee camp in the ruins of Chicago to attract the government's attention. The player will need to find resources and organize survivors. In the midst of Chicago’s ruins, the player will have to survive seven days."
It explains about why the water is so important, and pretty much confirms the water IS what the men were trying to get from Adam.
Yeah, I had seen it too. I think "the world" simply refers to the game world, and that's Chicago. Anyways, NO other source has said this - trust me, I've seen them all.
