ALIEN VS. X-MEN #4

The crossover reaches its last stand. Facing a full-scale Xenomorph invasion, S.W.O.R.D. decides there is only one option left to guarantee humanity's survival, and time is running out for the surviving X-Men to protect themselves and the planet.

As mutants clash with the new Alien Queen, something unprecedented and horrifying comes into being.

The issue also concludes Chris Claremont's backup tale pitting Kitty Pryde and Rachel Summers against the Xenomorphs. Kieron Gillen and Geraldo Borges deliver the finale. Parental advisory.
