This is the Core rulebook for the Marvel Superheroes roleplaying game, Saga Edition. The book scanned is in poor condition and has tons of highlights and notes everywhere, however I challenge you to find this book anywhere else. This file is meant as a backup only so your book doesnt have to get in as bad as shape as this one.
Also look for the 96 card Fate Deck that you need to play this game. Hopefully people are seeding it.
