Hahah, I found a combat shotgun last night, and my first thought was "Man, Petrarch would love this thing."
Also, not using VATS for radroaches is crazy! I mean, sure, if there's only one of them, just pop it, but if there's like four, there's nothing better than loading VATS, queuing one shot on each of them, then watching my guy blow them away in rapid succession.
