A friend and I wrote up rules for turning PF2 into a superhero game. We've been running it since September, set in Manhattan, in the Marvel Universe. 6 aspiring superheroes rushed into a bank when an alarm went off, starting a series of events that led them to form a team and eventually stop a city wide catastrophe.
Lots of fun, and it works really well, so far. We are at level 6 now.
So anyway, I'm posting the player/GM guide for the rules on how to do this conversion for anyone who wants a starting point.
This isn't the adventure we are running, just the technical stuff like vehicle chase rules, superhero archetypes, backgrounds, equipment, firearms, stuff like that. The most useful (maybe?) addition are 12 archetypes, that hopefully round out the PF2 classes and archetypes so you can build any type of superhero you can think of.
I'm always interested in more archetype ideas. I think writing them is a lot of fun. If you have a superhero concept that can't be created with PF2 and this guide, post below.
