Once a faction is sided with, it can still be possible to change to another faction's quest arc, only if there has not been enough infamy accrued to fail those alternative questlinesĬompleting parts of certain quests for a faction will immediately cause other factions' questlines to fail without exception.
The point at which the other factions' quests are failed varies depending on player actions and quests already completed. As the main quest arc for a single faction is followed, the quests for the other factions (with the exception of Independent/Yes Man quests) will fail as infamy is gained for siding against them when progressing through the quests for whichever faction was sided with. Main quest arcs įor these quests, one faction must be chosen to be loyal to. However, the path directly north from Goodsprings to New Vegas is highly dangerous.
Note: the entire story-line of They Went That-a-Way can be skipped by heading straight to The Tops in New Vegas to complete the quest.
