RedLynx announced today that Trials HD has sold over one million units on Xbox Live Arcade. The game’s second expansion, Trials HD Big Thrills, is set to release later in 2010.

“Only a handful of downloadable console games have reached this plateau,” said Tero Virtala, CEO of RedLynx. “For a company of about thirty-five people, it’s a significant achievement, and it validates our strategy of focusing on online and downloadable games that have the potential to evolve into long-term, successful game franchises.”

“Congratulations to RedLynx for creating such a beloved, fun game that powerfully showcases the Arcade experience,” said Scott Austin, director of digitally distributed games at Microsoft. “We look forward to bringing more Trials HD content to the Xbox Live community with the upcoming release of Big Thrills.”

“This is a satisfying milestone,” said Antti Ilvessuo, creative director and co-founder of RedLynx, as well as the lead designer on Trials HD. “But it’s just the beginning. With the Big Thrills DLC, we are including ten of the very best user-created tracks right alongside our own.”
