From the publisher's website:
How much trouble can a bunch of kids be? Quite a lot, when those kids were once the members of the world-famous Freedom League and they still have their amazing array of super-powers! Even more when the "kid" in question is the extradimensional imp known as Quirk, who's looking to play a dangerous new game with the heroes of Freedom City.
Little League is a Freedom City adventure for Mutants & Masterminds, intended for four to six power level 10 heroes.
M&M Capers provide GMs with affordable adventures suitable for playing in one gaming session.
