The Karma system is an important feature in Fallout's gameplay. A player's actions, including conversation and combat choices, affects the player's status in the game world; a player who makes good decisions is received more positively by non-player characters, and a player that makes bad decisions has the opposite reaction. Crimes can also be committed by a player, and whichever faction or group that is harmed by a crime are fully aware of the player's action in most cases. Other factions that were not affected by the crime will not be aware of it, and since a town is usually its own faction, news of a crime committed in one town will not spread to another. Beware however, good or evil deeds will cause a bounty by the opposite alignment group. Talon Company (If you are good) or the Regulators (if you've been bad) will ambush you randomly, and are not bound to any particular area, they can appear anywhere in the wastes. Factions can range in size and boundaries, however, and may not be restricted to a single area. The game world itself was planned to be significantly smaller than that of Oblivion's but is now similar in size.[2]
Not actually a fat man, which would in its own way be hilarious, the Fat Man is a "shoulder-mounted tactical nuclear catapult." In layman's terms, that means it's a hand held weapon that basically shoots nuclear bombs at people. It should certainly incinerate your target, but do be warned, there's a high possibility it will also incinerate everything around it (including your mates and possibly yourself), as well as leaving residual radiation.
The name comes from the second atomic bomb that was dropped on Japan in 1945. Unsurprisingly, in the game's Japanese release, this had to be changed, with the Fat Man becoming the Nuka Launcher in the Land of the Rising Sun. In Japan, the side quest whereby you can choose to detonate the atomic bomb in the town of Megaton was also removed from the game.
