Sony Secures Patent for NPC System Mirroring Player’s Gaming Style

Sony is venturing into the world of artificial intelligence with an innovative twist on multiplayer gaming. In a newly surfaced patent, the tech giant is developing a groundbreaking AI software that crafts NPC allies based on how players interact and play. This inventive system aims to revolutionize co-op gaming by allowing solo players to harness AI companions tailored to their unique gameplay styles, thus removing the barrier to multiplayer gaming.

The patent outlines a system where data from two players is gathered, with consent being imperative, to mirror their skills and personal style in NPCs. This not only makes the NPCs more realistic and personalized but also ensures that solo gamers can partake in multiplayer experiences without feeling left out or subpar.

Interestingly, artificial intelligence has often sparked debates in the creative industry, yet it’s been a staple in enhancing video games for decades. AI’s role in non-playable characters (NPCs) has evolved, and Sony’s latest software seeks to further deepen this evolution by offering a personalized touch to the typical NPC dynamics. With this patent, Sony could be preparing the groundwork for a major shift in how we experience multiplayer games.

Originally filed in August 2023 but only recently made public in March 2025, the patent describes a “generative nonplayer character” system powered by AI. This system lets players opt-in to have their gameplay style analyzed, enabling the creation of NPC teammates that could stand alongside—or even replace—human gamers. The potential here is massive, allowing gamers who shy away from playing with strangers to team up with virtual copies of their friends’ gaming styles. While this sounds promising, there’s currently no definitive word on whether Sony plans to bring this particular software to market.

The core idea detailed in the patent involves collecting gameplay data from at least two players to create NPCs that mirror their approach to gaming. By integrating this data with specific weighted metrics, the AI can generate companions that effectively replicate the skill sets and playstyles of actual players. For a solo gamer, this means no longer waiting around for friends to join a game. Instead, they could enjoy the thrill of co-op gaming with AI-trained partners that feel genuinely aligned with their own playstyle. And when human friends are available, they can seamlessly replace or join forces with these NPCs, creating dynamic multiplayer experiences. It’s still uncertain if Sony will push this or similar concepts to consumers, but this development offers a peek into their ongoing AI research.

Despite some skepticism around using AI in gaming, there’s no denying its potential benefits, especially in making games more accessible to everyone. Fans of the gaming world should keep an eye on Sony’s progress with its generative NPC technology and any other exciting AI projects on the horizon.
