X-Wing Rogue Squadron #18 represents the eighteenth installment of the Star Wars: X-Wing Rogue Squadron comic book series. Dark Horse Comics published it on May 7, 1997.
The assignment given to the members of Rogue Squadron seemed straightforward: locate and retrieve a group of Bothan survivors who crash-landed on Malrev IV. However, upon arriving at the remote planet, the Rogues were initially ambushed by the Irrukiine, a native species resembling canines, and subsequently by the very Bothans they were sent to rescue. A peculiar and unsettling phenomenon is occurring on Malrev 4—the environment fosters insanity and treachery, affecting even the Rogues themselves!
