Titanic: Adventure Out of Time is an open-ended first-person adventure game set on the doomed maiden voyage of the HMS Titanic. The player takes the role of Frank Carlson, a disgraced British secret service agent. His career having ended after he failed in a mission on board the HMS Titanic, he now lives in a small apartment, surrounded by mementos of his past. Somehow, however, Carlson is thrown backward into his past to April of 1912, giving the player an opportunity to change the events on board the doomed ship. While the player is not able to avert the sinking of the Titanic, they are able to influence not only Frank's timeline but that of the other passengers on board the ship and, indeed, the progression of subsequent human history. As a result, details of the game's plot are affected by the player's actions, which can result in one of any number of significant or minutely different endings.
