So running a d&d campaign.
Got the PCs in a heavily industrialized town, oppressive atmosphere ect. The quest demands they find out some intel, destroy a lab, erase some data and kidnap and/or murder some people .
Problem is, the PCs are terrible at infiltration. I mean, horrible. They've never really done anything similar before and I thought it might be a nice and new challenge for them. How do I get them to spy/sneak in to a place without just plain out telling them to do so?
