Vive-exclusive sci-fi shooter Raw Data has become the first virtual reality game to hit $1 million in sales in the space of a month.

Developer Survios made the claim in an interview with Fast Company, and said at least 20 percent of HTC Vive owners have purchased the action title.

Earlier this year, Raw Data also became the first VR release to top the overall Steam charts, although its stay at the summit was brief.

The game currently retails for $39.99 on Steam -- though it was launched at a discounted $31.99 -- and Survios believes the game's success is rooted in the VR market's "need" for a true triple-A experience.

"It's more expensive than anything for the Vive, and more people wanted that. By putting more money in [and] having a higher price point, we’re signaling to users that this is a triple-A title," explained studio CEO, Nathan Burba

"There's an opportunity to own a significant part of the marketplace if you’re willing to spend capital up front. There haven’t been too many big swings [at high-quality content]. I'd love to see another venture capitalist take a big swing or two."
