Well, that merchant in the bunker gets new stuff ocasionally, like when I return from a mission.
I wasn't paying so much attention, and I was bursting with everything I got, lol. And I'm not charging on super muties with an mp5. Good thing is there is plenny of 7.62, if you focus on mutant encounters you usually get more than you spend, even with three SAWs. Also after killing those laser turrets there are few thousand MF cells, so energy is no problem. Other weapons wouldn't be such a problem becouse there are so many of them, only thing is I don't have where to put them. Those lockers in the bunker are few and have souch small capacity compared to previus Fallouts. How can I store stuff in vehicles anyway?
