Epic Games has acquired a firm specialising in security and player management for an undisclosed sum.
Kamu is based in Helsinki and offers developers and publishers a range of services, including multiplayer game management, game security, game telemetry and anti-cheat technology that is used by over 100 million PC players around the world.
The firm has already been working with Epic on Fortnite, ensuring that the multiplayer is "fair for all players", according to the latter's CEO Tim Sweeney.
And Kamu will continue to serve other customers after the acquisition, regardless of the engine they use.
Meanwhile, Epic will use Kamu to establish a new presence for itself in Helsinki, enabling the firm to recruit more talent for developing its engine, online services and other technology.
"Building and launching games today is incredibly challenging, and only half the battle," said Sweeney. "Kamu's tools for managing live games help developers grow and sustain their games successfully after launch."
Kamu CEO Simon Allaeys added: "Joining the Epic family is not only a childhood dream come true, but a huge boost for our mission to help developers create beautiful gaming experiences. Battling cheating in games was just the start; today our products also help developers stay competitive by identifying player needs as quickly as they emerge."
Epic has taken a firm stance on cheating in Fortnite, even taking a 14-year-old player to court earlier this year.
