In " " , your reputation among various faction s will be tracked , and will even give you access to new areas in the game . There are many different factions in the Wasteland , and you can develop a distinct relationship with each one . As you perform actions that benefit a group , you will gain Fame . If you perform actions that harm a group , you will gain Infamy . Your reputation with any given group is a measure of the combined total of Fame and Infamy that you have earned .

Originally , any faction member could be killed without loss of reputation , though only if the player character remained [ HIDDEN ] or in [ CAUTION ] for the kill without it progressing to [ DANGER ] . This was changed in the December 14th update . Players now lose reputation for killing a faction member regardless of a successful sneak kill unless that weapon is silenced and the player remains completely hidden . However , due to an as yet unfixed bug , the faction reputation can reset at an unpredictable time . With every faction except Goodsprings , the Boomers , Novac and The Strip ( needs verifying ) your reputation will reset to neutral . However , any faction that was hostile towards you will remain so , despite the change . Support items like the NCR Emergency Radio will also become useless , and faction privileges like the McCarran monorail will be lost . There is no real way to fix this on consoles , apart from either restarting or reloading an earlier save , confirmed to happen on both casual and hardcore play modes . Some think that the reset of reputation is caused by committing an infamous act towards a faction while wearing that faction ' s clothing . For example , if killing a Powder Ganger while wearing a uniform of theirs , it might reset all faction reputations . The aforementioned bug has been confirmed on all platforms : A possible solution is to travel to the Mojave Outpost , put on non - faction clothing / armor , go to where Major Knight is located , save and then speak to Major Knight ; select the speech option asking if there is anything you can do to help . If your reputation with the NCR is above neutral , he will reply that you have done a great deal in a short time and advise you to ask around . Once the dialogue is complete , check your Pip - Boy . Your reputation will probably have reset from neutral to the proper standing . However , once you put on an NCR faction armor / clothing , there is a chance your reputation will reset back to neutral again . This tip can be useful however if you need to gain access to the NCR Ranger Safehouse , or to use the monorail , or for additional help during the You ' ll Know It When It Happens quest .
