"Stage 0," the first level in Vertigo Games' Oculus Rift-compatible World of Diving, is available for download to those who've pre-ordered the game from its official site.
The level released today supports both the Oculus Rift virtual reality headset and traditional monitors. "Stage 0" is designed to give players a sense of what to expect from the full game and allows up to four players to share the water.
"Launching an early, scalable build in this fashion allows a small studio such as ours to stagger the release in manageable chunks, while at the same time giving our ever-growing community the chance to get involved in a transparent and open development process from very early on," said creative director Richard Stitselaar.
Linux and Mac support "is expected in the next weeks" according to a press release from the developer.
