Now, I know the storyline is fuzzy, especially without the NPCs, but as far as I understood from Kate and Baldspot, something, probably the army, is blocking all communication in and out of the area the game is set in. Outside the game world everything keeps going on as normal, and they even mention something about showing the area on TV as "going on with their normal life", which means the rest of the world is completely unaware of what's going on inside the area. At least initially. There should, however, be some computers around. And you should be able to "play games" on them to ease boredom.
