I was thinking that it could be a puzzle/stealth game but there would be some fighting mixed in at various points of the game. Here's a summary of the story I have in mind:


The player plays as a young boy. The boy lives with his mother in a bad area of Southampton. His dad is absent from his life since he knocked up his mother then left soon after. The boy is a bad seed. He robs people, burglarizes homes, etc. One nite, he robs a man who has two third-class tickets to Titanic. He brings it home to his mother, who is American, and tells her that he bought her the tickets so she and him can go to America. He continues his antics on board Titanic and is soon recruited by members of the mafia to do work for them. Over the course of the game, he realizes the horror of true crime. During the sinking he has to get his mother and him off of the ship whilst avoiding the mafia.
