"The war did more than crumble the United States government and its infrastructure. It left behind a reminder of man's transgressions. The effects of radiation are felt everywhere, none more strongly than in the water. Thirst and desperation are constants in Fallout 3 and you won't know the true definition of either until you drink irradiated water from a toilet to gain a few health points. Water and food can heal you, but almost everything has been poisoned by radiation. You'll have to use medicine to manage the levels of radiation you take in from eating, drinking or wandering into hot zones, creating an unending give and take that underscores the struggle for survival that everyone you meet faces. Such pressure could make even a good man do bad things. For those who are already bad, it provides the excuse to do great evil and take advantage of the weak. You will have to decide where you fit in this world. If you want to be good, there are beggars to give water to and people that need a champion. If you want to be bad, well let's just say that you won't have any problem finding places to ruin lives. If you haven't figured it out yet, this is not a game for kids or anybody with a developing moral compass. Foul language is pervasive and that is often the smallest sin on screen. Fallout 3 shies away from sexual content and giving you the option to kill little kids, but that's about it. The world is filled with twisted people who do nasty things and you yourself are often presented with the option to perform terrible, terrible acts. Several times while playing as an evil character I found the situations so extreme and wholly wicked that I had trouble taking the low road."
