Sony has invested $250 million in Epic Games.
The gaming giant has taken its relationship with the company to the next level with a "strategic" investment to give it a minority interest in the 'Fortnite' studio.
In a statement, Sony said: "The investment cements an already close relationship between the two companies and reinforces the shared mission to advance the state of the art in technology, entertainment, and socially-connected online services.
"The investment allows Sony and Epic to aim to broaden their collaboration across Sony's leading portfolio of entertainment assets and technology, and Epic's social entertainment platform and digital ecosystem to create unique experiences for consumers and creators."
Meanwhile, Sony boss Kenichiro Yoshida has said the investment allows the firm to "explore opportunities for further collaboration with Epic to delight and bring value to consumers and the industry at large, not only in games, but also across the rapidly evolving digital entertainment landscape".
As it stands, Sony now has a 1.4% minority stake in Epic, with the company valued at $17.86 billion.
Tencent has a 40% stake after making a $330 million investment in June 2012, while Epic founder Tim Sweeney is still the majority stakeholder.
