The cover by John Romita Jr. and Al Williamson captures the sheer scale of the threat, with Spidey swinging hard against a sky scattered with debris, conveying the sense that the city itself is coming apart. With Howard Mackie writing and a "Must-Read" badge on the cover, Spider-Man #72 is a vivid snapshot of just how high the stakes climbed during "Onslaught Impact 2.
