Question! In the setting rules for Containment Breach, a rule called "Guts" is mentioned, but I can't find it explained anywhere within this book! I also can't find it in any other Savage Worlds books, but I may be missing the source. Was this rule included in SavTok but under a new name?
Sorry for the confusion! Guts is a setting rule from Deadlands but it's a pretty easy one:
You add a new Skill to the game called Guts. Instead of making a Spirit check to oppose Fear, you make a Guts check. That's all it is. Hope that helps!
