As you know it takes a certan amount of karma to get certan teamates.Well i can only find 'Evil' teamates, does anyone know were i can get 'Good' teamates?

There are a few "good" followers in the game. for example one of them is star paladin cross who is a follower that you can find in the citadel. also during the garden of eden quest ,i think, is the follower fawkes who u have to unlock from a locked roon in vault 82. both these characters require good charma to have them follow you. there is also dogmeat who i believe follows you no matter what,

You can get Fawkes in Vault 87 or you can get the Mister Gutsy that is just outside of the Robco Factory and follows the guy around.

Brotherhood of steel in Citadel Raily rangers or something like that in the Underworlds hospital! XD
