From publisher blurb:
Back with a vengeance! The Algernon Files brings you threats, potential allies, and other complications to liven up your Mutants & Masterminds games.
Learn to hate Abraxas, to fear The Alchemist, and to just avoid Apex as if your life depends on it – because it probably does! Fight Alpha Mech to earn macho cred, prove to Amalgam that copying your powers does not make him better at using them.
The Algernon Files 3.0 is a sourcebook for Mutants & Masterminds 3rd Edition. You’ll revisit classic characters from earlier editions, and meet new heroes, villains, and “others” as you go.
