Purple Duck Games acquired 4 Winds Fantasy Gaming several months ago. As part of this acquisition they inherited the Kickstarter for the Deus ex Historica product, a Mutants & Masterminds supplement.
Deus ex Historica is a 376 page book that explores the ages of the super-hero from the golden age of the 40’s to the modern age. The book is full of heroes, villains, and even adventure seeds for a superhero campaign.
Purple Duck Games just announced yesterday that this book has gone to a Pay What You Want pricing model. If you are an active supers RPG player, or curious about the genre you can get a look at the product and if you like what you see come back and pay for the product.
