HELP fallout 3 megaton settlers all atacking me!!!?

you can either load a previously saved game and not go in the armory (all armories have those robots in them) or you can escape the town and come back in a few days..all will be forgiven. (make time p yourself so its quicker). just remember to SAVE SAVE SAVE. save 2 or 3 files and frequently updated them. things like this happen all the time and if you dont, you have to start the game over. think if you had no health left and couldnt escape the city. if you only had one file, you would be done for. so have a couple on the go if you ever need to load from a certain point.
