Hi there and thank you for your kind words. Some background info about Führerbunker VR (FBVR): The documentary experience was created in co-operation with renowned historians (some were also historic advisors on the movie “The Downfall”) and have published many books about the Third Reich and the last days in the bunker.
We are a German team and the development was in part funded by the federal states of Bremen and Lower Saxony. Some footage of the documentary is used in the TV documentary “The Fall of Adolf Hitler” (which is not yet published). So, you could say that part of the work was commissioned.
Please note that only the VR experiences “Füherbunker VR” and “Arctic Meltdown” on Time & History are developed by NORD XR. The other experiences on that site were developed by the devs mentioned in the info boxes (including links to where to get them).
We believe that VR will change the way we learn about history in the future. This time might not be here already, but it will become a reality sooner or later.
