Riot Games is using the Unity games engine for two of its forthcoming current projects.
Both card title Legends of Runeterra and mobile MOBA League of Legends: Wild Rift are being built on the third-party engine. Riot wants to bring its games to more platforms than before - unity is optimised for over 20 platforms.
"Unity's technology enables us to focus on delivering the beloved League of Legends experience to as many players across as many platforms as possible," said Riot Games head of corporate and business development Brian Cho.
"We want to meet our players where they are, and Unity's world-class tools and platform optimisation help us achieve that. With the expert support provided by Unity, we've been able to unlock the power of Unity's technology like never before," said Brian Cho, Riot's corporate and biz dev chief.
Unity vice president of research and development Ralph Hauwert added: "We are focused on providing the solutions and technology that allows creators to immerse their players in fantastic worlds and experiences.
"Riot Games has woven such a rich tapestry with the world of League of Legends, and our technology now gives them the power to share the same consistent experience with more players, across more platforms, than ever before."
Legends of Runeterra is currently in open beta on PC, it will come to both iOS and Android devices later this year. Meanwhile, League of Legends: Wild Rift will hit mobile devices first, it will come to consoles at a later date.
"From the beginning, we wanted Legends of Runeterra to be available on both PC and mobile, so Unity was the obvious choice," said Legends of Runeterra engineering lead Dann Webster.
"We relied heavily on Unity's professional services team for ongoing support and performance advice; they've been absolutely integral to the ongoing development of our game."
League of Legends: Wild Rift and Legends of Runeterra were two of the six games announced by Riot Games in an anniversary live stream. Last month, League of Legends comms lead Ryan Rigney revealed the company was scared of potential backlash over the announcements.
Reportedly, a new survey by a Reddit user has shown that 79 per cent of League of Legends players have been harassed.
Riot Games is currently in a legal battle of gender discrimination. The firm has claimed a $10 million settlement was "fair and adequate." However, the new lawyers representing the plaintiffs have withdrawn the $10m as it is seeking a bigger compensation.
In January, California's Department of Fair Employment and Housing claimed that Riot should pay $400 million.
