The Blautopf cave system is one of the most spectacular natural phenomena of Southern Germany. It is only accessible to scientists. With BlautopfVR - The Secrets of Lau you can now explore these hidden places in a Mystery Adventure Game for HTC Vive. Every year, over half a million tourist are drawn to the Blautopf in Blaubeuren. What attracts them is a broad and branched cave system with meter-high stalactites, underground lakes and huge rock halls, which hides behind the karst-spring. Yet none of the tourist have ever been underground, inside the cave. For over hundreds of thousands of years, this has been uncharted territory. Only about 30 years ago, the cave system was discovered and has been successively explored ever since. Blautopf VR makes it possible for a broad audience to interactively discover the fascinating inner life of the cave system via Virtual Reality. With the technique of Photogrammetry, big parts of the cave were scanned and then digitally rebuilt. The creators designed the VR-Adventure Game BLAUTOPF VR – THE SECRETS OF LAU based on these virtual 3D-spaces. The player himself becomes a cave explorer, who is out on the search for his disappeared research colleague. On his tour, the player is accompanied by his missions chief Karl, who gives him directions via radio signal. Deep inside the cave, the player meets the mysterious figure of the Beautiful Lau, a personification of the cave itself, who depending on the players’ decisions, appears to him as an enemy or as a helpful ghost. This VR-Game is produced for the high-end VR headset HTC Vive System. A TELLUX NEXT/ SWR production in coproduction with KOHELET3 and IT MEDIA financed by MFG BADEN-WÜRTTEMBERG and FFF BAYERN.

A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.
