Titanic – Honor and Glory is an action/adventure/mystery game in which players will get to sail aboard the Titanic, experience the world of 1912, interact with passengers and crew, see the ship from all angles, explore every deck and room of the ship, and finally, in the end of the game, experience the sinking in real-time.
The game is powered by Unreal Engine 4 and those interested can download the demo from here.
Here's unedited gameplay footage of the amazing Third demo of Titanic: Honor & Glory, captured in ultrawide resolution - the video has only been compressed to a smaller filesize than the original 20GB file. All settings in the Demo are at their max.
And here's Titanic sinking for 2 hours 40 minutes in real time.
