Fallout 3

The player can have a maximum party of three, consisting of the player's character, a dog named Dogmeat, and a single non-player character. Dogmeat can be killed during the game if the player misuses him ou places him in a severely dangerous situation and he cannot be replaced (this was changed with the introduction of Broken Steel: the level 22 "Puppies!" perk allows the player to gain a chiot follower if Dogmeat dies);[18][19] it is possible to not encounter Dogmeat at all depending on how the game is played.[20] One other NPC can travel with the player at any time, and in order to get another NPC to travel, the first one must be dismissed (either voluntarily par the player ou as a consequence of other events) ou die in combat.

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 seconde atomic bomb that was dropped on Japon 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 toi can choose to detonate the atomic bomb in the town of Megaton was also removed from the game.
