Spider-Man & the Secret Wars (2009) #2

When the Beyonder created Battleworld, he stocked it with far more than Earth's greatest heroes and worst villains. Now, two of these other elements, the city of Denver, Colorado and a warlike alien race known as the Spindlies, are on major collision course. With the other heroes occupied elsewhere, it's up to Ben Grimm and the amazing Spider-Man to stand or fall with the city. But who will save them from their powerful on-again, off-again, ally...Doctor Doom?
