I know, right? There obviously isn't anything there as sophisticated as the defenses on my bunker, but that doesn't mean there mightn't be something cool. Like this one gun in Jack's office? A shotgun that shoots several bullets at once, and each of those bullets splits into even more bullets. I always wanted to try using it, but Jack was all durr durr recoil will kill you if the ricocheting bullets don't durrrrrr I'm a tool..

[ Hey look, an instance of Jack being right! ]
