no the only way to get good karma is to let the residents of tenpenny tower and the ghouls live together. this is done by talking to alot of people. the only good thing is i sudjest that u let roy Phillips in so that u get the ghoul mask. makes it where ferals wont attack you from a certain distant.
Yes.
vault 112 is north west of tenpenny tower but dont go there before you have killed alister tenpenny (you gain karma)
There is a traveling salesman named Tinker Joe near the Robco building near Tenpenny Tower. it's name is Sergent RL-3 but you can only buy it if your karma level is neutral.
Yes in fact it does! The same exact thing goes for Mr. Tenpenny. Wait until after you save Megaton though. Kill them both on the outside balcony of Tenpenny Tower. This keeps the Megaton settlers from attacking you, and if you are on the balcony it will keep anyone that's at Tennpenny Tower from attacking you.
In Fallout 3 you can have either Very Good Karma (750-1000, Good Karma (749- 250, Neutral Karma (249- -249, Bad Karma (-250- -749) or Very Bad Karma (-750- -1000). So Bad Karma would be the second worst Karma. If you mean "What Is The Second Worst Karma Rank" as in the title for very bad Karma @ lvl 29; then it is Demon Spawn.
The regluators.
help if you want good karma or catch if you want bad karma
That is level 15 evil karma.
Any level. You find them around. Depends on what fallout game you are playing. Some of the followers have karma requirements.
I assume you're talking about skill books and all of them are obtainable no matter what your karma is.
There are 8 permanent companions. Jericho and Clover if you have evil karma levels. Sergant RL-3 and Butch (the same guy from Vault 101) if you have neutral karma levels, Star Paladin Cross and Fawkes of you have Good karma levels, and Charon and Dogmeat regardless of karma level.
If you don't mind bad karma you can kill Kimba in Big Town.
