Unity Technologies, which makes the engine of Pokemon Go and other video games, has agreed to receive $400 million in a new funding round led by the investment firm Silver Lake.

If the round closes, it will be a big show of support for the company as it focuses more on offerings to help develop virtual reality and augmented reality apps, two areas that Silicon Valley has been keen to dive into.

Founded in 2004, Unity's software powers some of the world's most popular games, including Niantic's Pokemon Go and Tencent's Honour of Kings. Games and apps developed using Unity reach 2.4 billion devices, the company said.

Silver Lake is one of the most prominent investors in technology companies around the world, whose portfolio companies run from Dell to the chip maker Broadcom to Ultimate Fighting Championship, the mixed martial arts organization. The firm announced last month that it had raised $15 billion for its latest fund, one of the biggest devoted to technology deals.
