Aha, thank. I hadn't found him on RPG Geek before. I did search around for old Danger Patrol hacks and found some that were on storygames before it shut down. Most of what I found were for the Pocket Danger Patrol rules though. I will definitely check out his work.
I have another hack I'm about to finish tentatively called "Dungeon Patrol" (not very original, I know). That will likely be the last one I post.
I have written a complete hack for Blades in the Dark / Danger Patrol, but I haven't posted it because I was concerned it might impinge on John Harper's work too much. While DP is under the Creative Commons, BtiD isn't (to my knowledge) and given that it's his most popular game, I didn't want to infringe on his livelihood in any way.
That said, I kind of love how well the BitD classes and feel fit into Danger Patrol. I think DP is actually great for running a heist and with a few tweaks (like adding Heat, factions, and a way to track resources), it works pretty well and is mechanically much simpler than BitD.
Anyway, good luck with your hack!
