Britannic: Patroness of the Mediterranean recently left the port on Steam, offering a recreation of this sister ship of the legendarily ill-fated Titanic. This offers a virtual tour of the ship along "with gaming elements." This supports virtual reality, but this is not required, so it can be experienced on a traditional monitor. Here's the official trailer and here's more on what to expect:

HMHS Britannic can now be explored in authentic onboard environments in a wonderous VR and non-VR version. Produced using Unreal® technology you can experience key areas of the fantastic vessel and witness a real-time sinking animation, as well. See if you can escape the ship before she sinks!?! You can roam the decks or use a free-for-all camera to fly around enjoying the rich details. Emphasis has been on historical accuracy and the title has been produced by a talented team of historians in a collaboration with wreck divers, archivists, and other experts to ensure history is brought to life in the most impressive way possible.
