Issue description
Avengers Disassembled tie-in. "FOURTITUDE" Part 1 (of 3)
The FF goes "widescreen" in a tale of epic scope and proportion as Manhattan is cut off from the rest of the world by a fleet of miles-high alien spacecraft--and that's just the beginning! With the Avengers in disarray, New York reluctantly turns to the disenfranchised Fantastic Four, the only heroes in town, to save them--but where to even start?
