Astonishing X-Men #4

In "Unaufhaltsam," the Astonishing X-Men race against time as a seemingly unstoppable projectile hurtles toward Earth—only to discover it’s no missile, but a massive bullet with Shadowcat trapped inside. With Cyclops and the team split between confronting Powerlord Kruun and trying to stop the launch, the true nature of the threat unfolds in terrifying silence. As Colossus prepares to sacrifice himself in the Breakworld’s core and Shadowcat fights through a metal labyrinth, the line between weapon and victim blurs.

In "Fort," the X-Men and a team of Earth's heroes are summoned to S.W.O.R.D.'s orbiting base to confront the Breakworld's unstoppable bullet, a threat that demands every hero’s last effort. As Colossus battles Aghanne inside the reactor and Spider-Man grapples with the illusion of victory, the line between sacrifice and salvation blurs—especially when Shadowcat makes a desperate choice that may alter reality itself.
