Ship of the Doomed!

From Introduction: A luxury cruise-liner is hijacked (and if anyone asks why terrorists would hijack a cruise liner, shoot them), the captain has been shot, the radio has been shot, and the hijackers aren’t done shooting. No one understands what they’re saying, and they don’t speak any language anyone else does, so no one even knows if they have demands. Now the terrorists are executing a hostage every 15 minutes until, presumably, their unintelligible demands are met; the ship is heading into a violent tropical storm; and no one is steering. Can the characters survive this terrible DISASTER?!
