"The Ship", also known as "The Ship: Murder Party", is described as being "[...] primarily a multiplayer, online murder game with a unique set of game rules." This is "The Ship - Complete Pack", meaning it is the complete experience, including both "The Ship" (can't be bought separately on Steam, it seems), which is the multiplayer and online portion of the game, and "The Ship Single Player", which you can actually enjoy alone. A tutorial also comes with the game so that you can learn how to play this particular game.

***This being my first giveaway, I made a mistake earlier saying one person would get 2 initial copies of the game. I've since learned that "2 copies" means I will send a copy to 2 separate winners. Sorry for the misunderstanding! The following text was corrected.

As indicated, there will be 2 winners, each getting their own copy of the game. From what I understand, a copy of this game will give you an additional gift copy once activated so both winners can actually send another copy for free to one of their friends or something (this being primarily a multiplayer, online game after all). At least, that's what it claims in the Steam description, but don't hold me to it... I can only guarantee you both get your initial copy!
