A patent application titled “AI-Adapted Non-Player Character for Video Game Systems”was published on October 1, 2026.

Applications for conversations with NPCs and role changes are also envisioned

The published patent describes a system that uses AI to modify the behavior of NPCs—including bosses—based on the player’s combat style and in-game actions. It explains a mechanism that adjusts an opponent’s combat strategies, movements, and dialogue based on factors such as the weapons used and the player’s evasion tendencies.

Specifically, the system first collects data regarding encounters between the player and NPCs from the game console or similar devices. This data is then fed into a machine learning model, which generates information regarding NPC behavior, which is subsequently implemented in the game.

Examples of the information collected include weapons and techniques used; the frequency and timing of attacks; movement patterns such as dodging and positioning; the frequency and success rates of dodging, guarding, and parrying; damage dealt and received; and the outcome of battles, as well as the number of retries required to succeed.

Furthermore, the scope of application extends beyond combat; the document also presents examples where NPCs respond by fleeing, engaging in combat, or negotiating, depending on the player’s aggressiveness or in-game reputation. Dialogue options and NPC roles are also subject to change, and the document mentions the addition of NPCs to assist with solving puzzles.

However, this document does not specify which titles will actually adopt this patent or when it will be implemented.

On the international forum Reddit, some users expressed concern about this patent, questioning whether it’s appropriate for the difficulty to increase every time a player improves. On the other hand, others pointed out that some users might seek a higher difficulty level if the game becomes too easy, and suggested that the feature should be optional.

In addition, some users pointed out that “such mechanisms already exist,” citing titles like *Resident Evil* and *Left 4 Dead*.
