Not quite, you won't be issued with anything that can't be explained. So while you won't be given gatling guns and sent off into a typical Copper Age world, you might be given gatlings, sent into a magic-heavy Copper Age world, and told to call them magic wands.Considering L.U.S.T. is a multiverse hopping organization. I assume they're going to give us dimension-appropriate gear?
Like, we're not going to be getting gattling guns and heading off to a Copper Age society...as fun as that may be
Also, L.U.S.T. tends to solve problems via dialogue or sex, rather than copious amounts of firepower (that's the Hunter's Society), so you're not likely to be given guns any more powerful then for simple self-defence... unless the situation is something like in Blood and Iron, where in order to pursue the aims of L.U.S.T you're going to have to shoot people.
