The Ship - Complete Pack (PC) Steam Key Global

The Ship is primarily a multiplayer, online murder game with a unique set of game rules.

The Ship is owned by the mysterious Mr X and as one of many "lucky" recipients of a free ticket you arrive on board The Ship to find there's a catch to your luxury cruise. 
You are coerced into a brutal Hunt to indulge Mr. X's fantasies, under threat of death for not only yourself, but also your family. Your only chance to save yourself and your family is to play the Hunt and win.

This single player mission based campaign provides a good introduction to the world of The Ship.
