Desperate times often call for desperate measures. When fresh water is a rare find and most of the food available is just as full of radiation as it is nutrition, simply making it through the night is the definition of success. And sometimes, somebody else has to die for you to do that. Such is life in Fallout 3, Bethesda's upcoming post-apocalyptic role-playing game for Xbox 360, PS3 and PC. The game may keep track of your good and evil deeds through a karma system, but even the most angelic of characters will have to get their hands dirty if they value their lives. To do that, you're going to need some weapons.
