Simple question - to obtain this quest I can't have negative karma with Gun Runners? Becouse so far Marshall don't wanna give me this quest, when I ask if they hire mercenaries he says they do but I dont look like I could handle the job and when I ask what do Gun Runners do and then if he has any job for me he says they could kick my ass out of there. My character has 3 charisma, 13 lvl and 176% SG so according to Wiki i do meet requirements. However since I joined Slavers and Brotherhood of Steel i got -100 reputation with them.
Any tips? Cuz I'd like to boost my rep with them so I could gain access to their advanced workbench.
