From publisher blurb: What if there were parallel universes endlessly stacked upon each other like pages in a book? What if there were millions of versions of you, spread out through the multiverse? What if someone figured out how to make you more powerful... by eliminating those parallel “yous”? Welcome to QUANTUM COLLAPSE, a new table-top roleplaying setting built on the Mutants & Masterminds 3rd Edition rules system. In QUANTUM COLLAPSE players will be portraying super-powered heroes in a world just discovering the ability to explore and manipulate the power of the multiverse. QUANTUM COLLAPSE brings the power of the multiverse to your gaming table, but be careful! Somwhere in the multiverse, your hero is on someone's hit list... maybe even his own!
