Take-Two Interactive have applied for a patient with USPTO that has started to stir up some rumors involving Grand Theft Auto VI. This is due to the patient being related to software code that would involve NPCs and navigation between multiple islands.
What adds credit to it being related to Grand Theft Auto VI is that the investors are current employees at Rockstar Games. The two inventors are David Hynd (Associate Director of Tech. at Rockstar) and Simon Parr (Lead AI Programmer at Rockstar).
