Green Ronin is preparing to release the second supplement for its Mutants & Masterminds superhero role-playing game.  Lockdown, a 128-page perfect-bound, full color sourcebook, has a suggested retail price of $26.95 and it presents a complete prison for supervillains, detailing all four levels of the Buckner Ridge Superhuman Penitentiary, the first privately run super prison.  Lockdown provides profiles on various inmates and factions within the prison itself as well as the nearby town of Buckner Ridge.

There are many ways to use Lockdown in conjunction with a Mutants & Masterminds campaign.  It can be the focus of an entire game or it can be a background element, and it also contains a conspiracy scenario that could result in the end of the prison and unleash its powerful prisoners on an unsuspecting world.
