Why did the Enclave gun down those people who were coming out of the vault? they were pure human, no mutation... unarmed... surely useful to the Enclave for recruitment and breeding and any number of things, they would seem to be natural allies.
So did I just forget something, or did it never really make any sense and it was just the guys who made Fallout 2 thinking "huh huh, this'd be cool for the opening, [censored] yea! they'll just like, totally blow them away!" (sorry, I don't have the greatest respect for Fallout 2, I'm a Fallout 1 fan)
