Play the modern Roblox Titanic https://www.roblox.com/games/294790062/Roblox-Titanic This game ran its course August 2009 to December 2015. Thanks to everyone who played it. Roblox was just in its infancy and this game has grown along with Roblox. It was made without a security feature, due to being built before that feature even existed, and Roblox has made it mandatory as of July 2018. You can actually get to a barebones version of this game by playing Roblox Titanic 2.0 (link above) and finding the option in the lobby gallery hallway. You will see an option to play Roblox Titanic Classic. It will not be the same, but you can explore the ship and experience the sinking.
