Walk Through The Titanic At Unbelievable Full Scale and Detail!
This is actually a preview walkthrough of the Titanic which will feature as part of a game still to be released (all rendered using Unreal Engine 4). It is such mindblowing detail that with a 3D view you'd easily think you are really walking through the ship. Have a close look at the finer details like the heat waves emanating from the boilers at around 8:11.
The game is titled Titanic: Honor and Glory with the release date still to be announced. Many would probably just buy this without the gameplay to enjoy walking through the ship!
