Austin indie video game studio Certain Affinity -- the company behind a successful reboot of "DOOM" and a player on the "Halo" and "Call of Duty" franchises -- said Monday that it has landed a new investor.

Hong Kong-based Leyou Technologies Holdings Limited said it has acquired a 20 percent stake by investing $10 million in Certain Affinity, which has more than 125 full-time employees.

Leyou Technologies plans to loan Certain Affinity up to $15 million for development of a new game based on licensed intellectual property. Leyou has the option to buy all remaining shares of the company in 2021 on a valuation not to exceed $150 million. Certain Affinity had a previous $5 million investment from a private investment firm, Austin’s Capstar Partners.

Certain Affinity was founded in December 2006 by Austin native Max Hoberman, who was a veteran of Bungie Inc., the company behind "Halo." Its bread and butter for years has been contributing to mega-blockbuster game franchises. This year, as the company was preparing move to a new headquarters on North Guadalupe Street, Hoberman said Certain Affinity was working on two original, self-funded games as well as some virtual-reality projects.

"This agreement launches a partnership to create an ambitious and exciting new game together, while the additional investment allows us to continue developing our own original IPs," Hoberman, the company’s president, said in a written statement. "Certain Affinity has a history of co-development on some of the biggest action franchises in the industry, and we will continue this work in parallel. Our commitment to growing the company and expanding our presence in Austin has never been stronger."

Alex Xu, CEO of Leyou Technologies, said: "With its proven track record producing high-quality video games, Certain Affinity possesses the technical capability and talent to create highly successful titles, which in turn will assist Leyou in further diversifying its video game portfolio and enhancing its revenue streams.,"

Certain Affinity said games its worked on have sold more than 75 million copies and the company has generated more than $100 million in combined revenue for the Austin area. Leyou Technologies has published free-to-play online multiplayer games including "Warframe" and "Dirty Bomb."
