From publisher blurb: Throughout the history of superhero comics, the concept of a multiverse has been used by numerous publishers to allow for characters to go on non-canon adventures, explore story options that would dramatically alter the primary narrative of the heroes and ask the question, “what if...?” Superstring Multiverse is an attempt to recreate that freedom in your M&M tabletop game. Utilizing the characters from our Superhero Support line of products as a base starting point, we have decided to craft a vast and complicated multiverse of parallel worlds and infinite options to integrate into your game. Within the Superstring Multiverse core supplement we will explore basic ideas and theories on the operation of the Multiverse. We will also introduce a few new powers that facilitate travel between worlds and provide some guidelines on different ways to integrate characters from one world to another. Whether you would like to play a band of dimension- hopping heroes chasing down cosmic threats from reality to reality, or simply run the occasional one-shot session looking at your regular characters through the lens of another world, we’ve got you covered. Superstring Multiverse includes: New Powers and Extras for traveling to parallel worlds along the Superstring. Eleven new character stat blocks, ready for inclusion in your M&M campaign. Four alternate world descriptions with detailed rules for stories within those settings. Detailed Origin Descriptors for all characters in previously published Superhero Support materials
