Superstring Multiverse
A supplement for superhero tabletop campaigns focused on parallel worlds and alternate versions of familiar characters. It introduces powers and Extras for traveling between dimensions, guidelines for moving characters across realities, and four alternate-world settings with rules for adventures in each. The book also includes eleven ready-to-use character stat blocks and Origin Descriptors for characters from previously published superhero support material. It supports both ongoing campaigns about dimension-hopping heroes and standalone stories exploring alternate versions of established characters.
