The latest issue of the Over The Wire e-zine from Darkson Designs includes rules for building your own Pulp heroes.
From their website:
We’d like to share with you the latest issue of Over the Wire, Issue # 15. In this issue we include trial rules for superheroes in your games of AE-WWII. We’re also updating the style and format of OTW. Let us know what you think about both the content and the new layout.
We have some plans to expand upon these rules in the future, but we’d like your feedback first. Enjoy! We hope you all have fun with this issue. There are many more yet to come for this year.
