HARP Steampunk sourcebook cover art from Iron Crown Enterprises

Iron Crown Enterprises just dropped HARP Steampunk, a new sourcebook by veteran designer Phil Masters (yes, the same Phil Masters who wrote GURPS Steampunk and GURPS Castle Falkenstein, so the man clearly has a type). It hit DriveThruRPG in PDF form simultaneously with a physical premiere at Gen Con, and it’s already the top-selling Phil Masters title on the platform. The Doctor approves of this velocity.

The book bolts the HARP system onto Victorian melodrama, weird science, and Jules Verne retro-sci-fi, delivering 12 new Steampunk professions: Detective, Doctor, Engineer, Pilot, and more. You also get mechanical rules for clockwork automata, steam-driven contraptions, ornithopters, steam-powered power armour, and something called Akashic Reading, which sounds exactly as gloriously unhinged as it should. Settings are modular, scaling from grounded Victorian realism all the way up to “electrical miracles,” so your table can calibrate from Sherlock Holmes to The League of Extraordinary Gentlemen depending on how much absinthe the GM has had. Note that this is a sourcebook, not a standalone: you’ll need either the HARP Fantasy or HARP SF core rules to run it. PDF is $20.00. High-5, Iron Crown.
