Just to clarify my understanding of the Custom Full-Bore Machine Gun:
Weapon text: "When you defeat one or more infected during this turn, gain 1 XP"
1) Do you get an XP for each infected defeated during the turn? Given the response regarding Barry's ability above, I would assume yes.
2) Does the effect of the CFBMG stretch across separate explores in the same turn?
ex. I have a hand with the CFBMG and another weapon with 2 explores. I choose to explore separately. I first explore with the CFBMG and defeat an infected, earning 2 XP (one for the explore, one for the kill). I do some other things, then explore again using the other weapon and defeat an infected. I get another XP for the explore. Do I also get an XP for this second kill?
