Nekki, the Moscow-based free-to-play developer and publisher, has announced that its games have surpassed 250 million installs across mobile, social, and browser-based platforms.

This, acording to AppAnnie, makes Nekki the second biggest games publisher in Russia.

This is more impressive when you consider that the firm's focus is on action games - Shadow Fight 2 and Vector being its flagship titles, each boasting more than 80 million worldwide installs - meaning that its products are more niche in style than broad-appeal casual games.

Saying no to UA

Furthermore, Nekki prides itself on the fact that it has spent barely any money on user acquisition, thus attributing its success to the quality of its games and word-of-mouth discovery.

"We have always strived to create games that make players feel strong emotions - from achievement and triumph to the right amount of disappointment and determination," says Nekki CEO Dmitry Terekhin.

"The fact that our games could attract a quarter of a billion people from all over the world just by word-of-mouth is a testament to the whole team and all the hard work they have put in over the years."

Buoyed by this milestone, Nekki has also taken the opportunity to announce that Vector 2 - a sequel to 2013's parkour-inspired runner - is set for a launch on the App Store and Google Play before 2015 is out.

In the meantime, if you're not one of the 80 million who already downloaded it, you can grab the original Vector on the App Store and Google Play.
