Prague-based independent developer Keen Software House says that its space-based sandbox game Space Engineers has sold more than 500,000 copies on Steam Early Access. That's not too shabby for an indie game that has been on the market since Oct 23, 2013.
Space Engineers is an open-ended sandbox game that features the application of real world science, physics, and engineering mixed with a dash of science fiction. The developers attribute the success of the game on Steam to good old fashioned community-driven word of mouth, an incredibly passionate fan base, and the creativity of its players.
The development team is now focusing on optimizing and improving the multiplayer performance and implementing new features and fixes that will make the gameplay experience better. Since the game is an "Early Access" title, it will be in development for the foreseeable future.
"We are very excited to celebrate this milestone with our fans, whose encouragement and active participation made this possible," said Marek Rosa, CEO and Founder, Keen Software House. "As an independent developer, finding an audience of this size, with this kind of support for our game – even while the product is still in development – is incredibly inspiring. The fans, with their limitless ideas and passion, continue to push us to improve, add features, and develop innovations that our community deserves."
