The Marvel Universe is being torn apart. You and your team of Marvel Super Heroes help Nick Fury launch a secret pre-emptive strike against Latveria and Lucia Von Bardas only to have to thwart her retaliatory attack on New York City.

Coupled with other Super Hero incidents, public sentiment turns against Super Heroes. The Superhuman Registration Act becomes law and Super Heroes must register as weapons of mass destruction and become licensed government agents with the United States government.

Lines are drawn as Iron Man leads the Pro-Registration side while Captain America leads the Anti-Registration side. You must pick a side and fight to determine the fate of the Marvel Universe and humankind.

Whose side are you on?
